When it comes to database security, one of the fundamental aspects is the importance of employing strong passwords and multi-factor authentication. These measures provide an additional layer of defense against unauthorized access, making it more challenging for malicious actors to breach your database. Understanding and implementing multi-factor authentication can significantly enhance the security of database access and prevent potential data breaches.

Furthermore, it’s crucial to be proactive in recognizing and mitigating insider threats, as well as implementing physical security measures to protect the servers where your data is stored. By incorporating these strategies, alongside other essential security measures, you can effectively safeguard your database from potential breaches and security risks. Let’s delve into the 10 tips for keeping your data safe and secure in the digital landscape.

Importance of Strong Passwords

Implementing strong passwords is the first and most fundamental line of defense in database security. Verizon’s research underscores that many cybercrimes are facilitated by compromised passwords. Hence, robust password protection is not just recommended but essential to thwart unauthorized changes to databases and safeguard sensitive data from potential attacks.

A well-crafted strong password serves as a sturdy barrier, making it exceedingly difficult for cyber attackers to utilize brute force methods to gain entry. However, the strength of a password also rests on its ability to be memorable without being predictable. It’s this balance that ensures both security and usability.

Furthermore, integrating Multi-factor authentication (MFA) supplements password security by necessitating additional verification steps. This security measure significantly diminishes the risks associated with password theft, firmly securing database access against external threats and safeguarding valuable information such as credit card details, trade secrets, and more.

Considering the security risks, it’s clear that both individual users and security teams must prioritize the creation of strong passwords and enforce a strong password policy to effectively protect against unauthorized access and ensure the integrity of database systems.

Multi-factor Authentication

Multi-factor Authentication (MFA) acts as a crucial bastion in the face of rising cyber threats, ensuring that database security remains robust and reliable. MFA is not just an optional extra; it’s an essential component of modern cybersecurity protocols. By requiring two or more forms of identification to validate user access, MFA creates a multilayered defense that significantly complicates unauthorized attempts to infiltrate sensitive database systems. Even if a password falls into the wrong hands, MFA stands as a formidable barrier, safeguarding against unauthorized access and preventing potential breaches that could compromise critical data.

Understanding Multi-factor Authentication

Multi-factor Authentication is a security process that bolsters login procedures by demanding additional verification from the user—a second layer of proof to further confirm their identity. At its core, MFA integrates two or more independent credentials: something you know (like a password or PIN), something you have (such as a mobile device or security token), and sometimes, something you are (including biometrics like fingerprints or facial recognition). The power of MFA lies in the premise that even if one element is breached, attackers still face additional hurdles before gaining access, thus drastically reducing the likelihood of unauthorized entry.

MFA Component

Examples Purpose
Knowledge (What you know) Passwords, PINs Verifies user identity through memorized information
Possession (What you have) Security tokens, mobile phones Uses the user’s devices as proof of identity
Inherence (What you are) Biometrics such as fingerprints Leverages biological traits unique to the individual

Implementing Multi-factor Authentication for Database Access

To weave MFA into the fabric of database security, organizations must follow a strategic implementation process. First, conduct a thorough analysis to identify which databases hold sensitive information or are particularly vulnerable to security threats. Once identified, these databases should be prioritized for MFA integration. Additionally, a robust cybersecurity awareness program should be put in place, training employees about the critical nature of MFA and how it protects against social engineering attacks like phishing.

Adopting MFA can appear daunting, but the process can be broken down into manageable steps:

  • Choose an MFA method that aligns with your organization’s needs and infrastructure.
  • Distribute physical authentication devices or set up digital app-based tokens if required.
  • Schedule regular training sessions to ensure all users are comfortable with the MFA process.
  • Regularly review and update MFA settings to adjust to new security threats or changes in personnel.

Given that Microsoft research indicates MFA can prevent 99% of automated cyberattacks, integrating MFA not only drastically bolsters database security against unauthorized access but also demonstrates a company’s commitment to protecting its assets and users’ data. Combining MFA with other security practices like strong passwords and regular monitoring of suspicious activity transforms database security into a formidable structure, resistant to both brute-force assaults and more sophisticated cyber threats.

Unauthorized Access Prevention

Securing database environments against unauthorized access is pivotal to safeguarding sensitive data assets. Comprehensive measures, integrating both physical and digital defenses, aim to prevent intrusions that could lead to data breaches or malicious activity. One principal component in this security strategy is real-time monitoring, which alerts administrators to any anomalous behavior or potential security threats, allowing for swift intervention. Moreover, a systematic approach to managing and controlling database access rights is crucial, comprising both preventative measures like encryption and detective controls such as robust activity monitoring systems.

Monitoring and Controlling Database Access Rights

Maintaining stringent control over who has entry to a database is key to a robust security posture. Administrators must implement administrative controls to oversee installation, change, and configuration, while also harnessing encryption and data masking as proactive safeguards. Detective controls, like database activity monitoring tools, play a vital role by pinpointing and notifying of atypical or dubious activities connected to database access. To ensure security measures align with overarching organizational objectives, database security policies should reflect the imperative of defending vital intellectual property and comply with strict data protection regulations. Audit logs serve as crucial security elements, acting as vigilant overseers that protect the database landscape from threats and offer valuable insights during post-incident analyses.

Implementing Access Control Measures

Access control measures are necessary to limit exposure to sensitive information. This includes creating and enforcing granular permissions, so that only authorized users or procedures can handle critical data. Role-based access control (RBAC) systems streamline user permissions management, assigning roles with specific privileges tailored to individual job functions. Access control lists (ACLs) are deployed to meticulously prescribe who can access certain resources and at which levels of authorization— whitelists and blacklists can each play a part in this delineation. To reaffirm the integrity of these measures, regular audits are mandatory to validate that security patches have been correctly applied and that databases operate as anticipated. Furthermore, detailed records of patching activities—specifying the patches applied, timings, and any technical issues encountered—are an essential documentary practice, reinforcing the overall security structure around database systems.

Insider Threats

Insider threats loom large in the world of database security, often commanding the center stage when it comes to network attacks. With over 60 percent of these incursions attributed to those within an organization, the risk they present cannot be overstated. Not only do these threats arise from malicious or negligent authorized insiders who may exploit their access for deleterious purposes, but also from unauthorized insiders who have skillfully sidestepped external defenses to infiltrate the system. The threat spectrum ranges from employees to contractors and partners, all of whom have varying degrees of access to databases and the potent secrets they hold. Nearly 400,000 exposed databases noted between the first quarters of 2021 and 2022 shine a stark light on the magnitude of this problem. The fact that more than half of cybersecurity experts pinpoint insider threats as a prime concern underscores the urgency of addressing these risks with effective countermeasures.

Recognizing and Mitigating Insider Threats

Given their prevalence and potential for damage, identifying and counteracting insider threats is crucial for database security. Insider incidents often lead to severe repercussions, including the theft of sensitive data, file destruction or modification, data loss, and the introduction of malicious backdoors into database systems. Recognizing these threats involves a two-pronged approach: understanding the behavior that signals a possible threat and limiting access to ensure that even trusted insiders can only reach data essential for their roles.

One practical strategy is to deploy strict access controls, such as the principle of least privilege, ensuring users receive no more access than is necessary to perform their job functions. Enforcing a strong password policy, employing robust encryption, and consistently applying security patches further strengthen the line of defense. Awareness training for staff plays a complementary role in reducing the risk of accidental insider caused breaches.

Establishing Insider Threat Detection Protocols

Establishing detection protocols to identify potential insider threats is a fundamental step in safeguarding database systems. These protocols comprise both technical solutions and procedural safeguards designed to detect suspicious or anomalous activity indicative of an insider threat. Security professionals emphasize the importance of having a comprehensive detection system that includes:

  • Real-time monitoring of user activities to detect unusual patterns or deviations from typical behavior.
  • Analyzing network traffic for irregularities that could signify an insider at work.
  • Implementing robust authentication methods, such as multi-factor or two-factor authentication, to impede unauthorized access.
  • Regular audits of user access rights and privileges to maintain a clear view of who has access to what data.

To operationalize these detection protocols, organizations often form specialized security teams tasked with monitoring, analysis, and incident response. Training these teams to recognize and react to the tell-tale signs of insider threats, coupled with the deployment of automated threat detection tools, can significantly enhance the overall security framework, and reduce the likelihood of a successful insider attack.

Physical Security Measures

Physical database security is a cornerstone of robust data protection strategies, extending beyond virtual threats to encompass tangible, real-world considerations. Meticulous attention to safeguarding the physical components that house critical data is as essential as defending against cyber threats. Recognizing this, modern data centers adopt rigorous physical security measures, leveraging technology and best practices to thwart unauthorized access to servers and related hardware.

These actions, in conjunction with maintaining rigorous standards and compliance with ISO 27001, NIST SPs (like SP 800-53), and SSAE 18, among others, help protect the integrity of the physical servers and the invaluable data they store.

Controlling Access to Server Room

Controlling server room access is a paramount practice for ensuring the safety of sensitive database systems. Measures include:

  • Access Logging: Every entry and exit from the server room should be accurately logged, enabling traceability.
  • Alert Generation: Automated systems should be in place to trigger alerts for any unusual access patterns.
  • Restricted Entry: Access should be limited strictly to essential personnel, typically vetted systems administrators, network engineers, and authorized members of the security team.
  • Server Room Standards: Adhering to recognized standards such as ISO 20000-1, SOC 1 Type II, and SOC 3 reaffirms an organization’s commitment to industry best practices in server room management.

Moreover, keeping hardware in locked, dedicated rooms controlled by stringent access protocols is vitally important. For a wider reach of database security measures, it may also involve hosting services with high reputations for security or ensuring strict access and security measures for self-hosted server environments. These steps are fundamental in constructing a defensive barrier against unauthorized entries and the ensuing security risks.

Suspicious and Malicious Activity Detection

In the realm of database security, vigilance against potentially harmful actions is nonnegotiable. Comprehensive audit logs are the backbone of this proactive stance, meticulously recording every action within the database, be it a mere login or a complex data alteration. These logs serve as a critical tool for pinpointing any unusual or unauthorized activities that deviate from the norm. For instance, spotting multiple failed login attempts could signal a brute-force attack, whereas unexpected data modifications may indicate an insider threat or a security breach in progress.

Real-time monitoring complements these audit logs by offering immediate insights into the database’s health and operations. This dynamic surveillance goes beyond passive observation; it is a strategic implementation of alerts triggered by suspicious activities, functioning as an early warning system for security personnel. Alongside performance benefits, this real-time vigilance ensures that any operational hiccup — potentially symptomatic of a deeper security issue — is promptly addressed.

Implementing Security Measures to Detect Suspicious and Malicious Activity

To fortify databases against nefarious deeds, a robust security infrastructure must be in place. This includes the integration of Database Activity Monitoring (DAM) along with file integrity monitoring software. These specialized tools augment standard logging and auditing by providing security alerts that are independent of the database’s native functions. Furthermore, dynamic profiling forms a formidable barrier, identifying and blocking dubious queries that could precede or constitute a Denial-of-Service attack.

For a strategic approach to database security, consider the following measures:

  • Two-factor Authentication: An indispensable layer that adds depth to the defense, ensuring that even if passwords are compromised, unauthorized access is still hindered.
  • Strong Password Policies: A simple yet effective measure obliging users to create passwords that are as resistant as possible to being cracked.
  • Regular Updates & Patches: Ensuring that all security management software is current and fortified against recent threats.

Establishing Protocols for Responding to Detected Threats

Proactively detecting threats is only half the battle; an organized response to these threats is equally crucial. Upon the identification of suspicious or malicious activity, escalation protocols must be prompt and decisive. To facilitate this, an actionable playbook should be devised, detailing steps from an initial alert to the resolution of an incident. This ensures that when an audit log flags a potential breach, the security team can spring into action without hesitation, securing the database against the compromise.

Regular training sessions sharpen the security team’s ability to recognize and respond to security threats, an endeavor that should be supplemented with continuous education on the ever-evolving landscape of cybersecurity. Together with reliable software solutions and stringent monitoring, these response protocols embody a holistic approach to database security that significantly heightens its resilience against undetected compromises and data exposure.

Proxy Servers and Remote Access

Proxy servers are an integral component of an organization’s security framework, especially when it comes to managing remote access to database servers. These servers act as intermediaries by evaluating and filtering every incoming request, thereby functioning as a gatekeeper that only allows authorized traffic to pass through to the database servers. This mechanism helps to mitigate security risks associated with malicious actors trying to gain unauthorized access to sensitive information.

Utilizing Proxy Servers for Secure Remote Access

In an age where data breaches are increasingly common, proxy servers provide a critical layer of defense. HTTPS proxy servers are particularly advantageous for handling sensitive information. The use of encryption that comes with HTTPS helps protect data as it travels through the server, which is especially important when the data in question involves trade secrets or credit card information.

Proxy servers can effectively act as a firewall between internal systems and the public internet, preventing direct access to database servers and thereby securing network assets. By vetting the users and traffic that seek to interact with the database, proxy servers play an essential role in protecting against potential attacks, including injection attacks and denial of service.

Here is a tabulated summary of how proxy servers enhance security:

Importance of Two-factor Authentication

In today’s digital age, databases hold an immense volume of sensitive information, from personal details to financial records. With cyber threats growing more advanced and frequent, securing these databases has never been more critical. A cornerstone of this security is two-factor authentication (2FA), which elevates the defenses against unauthorized access and potential data breaches. Unlike the conventional username and password, 2FA introduces a second layer of verification, such as a one-time code sent to a mobile device or biometric data like a fingerprint scan. This dual-step verification process means that compromising a password alone is not enough for intruders to gain entry, thereby significantly reducing the likelihood of security breaches.

2FA not only thwarts unauthorized login attempts by adding this extra hurdle but also serves as an effective deterrent against various security threats, including phishing attacks and identity theft. For industries handling critical data, such as finance and healthcare, implementing 2FA isn’t just a recommendation—it’s often a required security measure to ensure compliance with regulatory standards. It becomes an essential tool in the arsenal of a security team, protecting everything from credit card details to trade secrets. By requiring this second proof of identity, 2FA offers a fortified gatekeeping mechanism, safeguarding sensitive information and providing peace of mind for users and organizations alike.

Implementing Two-factor Authentication for Enhanced Security

Implementing two-factor authentication across online platforms and databases is a proactive step towards fortifying security measures. This can be as simple as setting up a system where users receive a text message with a verification code or as sophisticated as using biometric authentication methods. For instance, major online services like Google enforce 2FA, sending users a verification code to complete the login process and ensuring that even if a password falls into the wrong hands, unauthorized access is still barred.

Moreover, 2FA serves as a critical defense layer against common attack vectors, including phishing and injection attacks. By establishing strong password policies along with two factor authentication, organizations can considerably diminish the likelihood of malicious actors successfully hacking into user accounts or database servers. Adapting to this security measure ensures that both physical servers and remote access points are shielded against potential attacks, making it a top priority for any security-conscious business.

Educating Users on the Benefits of Two-factor Authentication

Education is a pivotal component in the effective implementation of two-factor authentication. Users must understand not only how to set up and use 2FA but also the substantial security benefits it provides. By raising awareness about the dangers of phishing scams—where attackers impersonate trustworthy contacts to harvest personal information—organizations can encourage vigilant and informed behavior.

It’s essential to inform users about dynamic profiling and its role in detecting unauthorized queries and potential denial of service attacks. This context highlights the invaluable nature of 2FA in database protection. Regular security training can help familiarize users with proactive security habits, such as employing a password manager and recognizing suspicious activity. When users comprehend how 2FA works as a security measure and its role in safeguarding their personal information, they are more likely to embrace and correctly use it.

Merging two-factor authentication with an organization’s overall security protocol, and involving both the security team and users in its adoption, is a decisive step toward mitigating security risks and ensuring a robust defensive posture against the evolving landscape of cyber threats.

Protection of Trade Secrets and Sensitive Information

In the business realm, trade secrets and sensitive information represent the cornerstone of competitive advantage. The unauthorized disclosure of such data can lead to catastrophic consequences, including financial loss, legal liabilities, and erosion of customer trust. To mitigate these risks, it is imperative to implement robust database security practices.

One of the most effective measures to protect these vital assets is to deploy HTTPS servers. These servers ensure that all data in transit is encrypted, creating a secure tunnel for information exchange. This encryption serves as a safeguard against eavesdropping and man-in-the-middle attacks, which are common on the internet.

Additionally, understanding why trade secrets and sensitive information are prime targets for cyber threats provides insight into defense strategies. Awareness of attack vectors and motives leads to stronger security protocols that anticipate and neutralize threats.

By classifying data into categories—public, private, confidential, and restricted—and assigning the appropriate access controls, organizations limit exposure to potential breaches. This data-centric approach to security ensures that only authorized personnel have access to sensitive data, effectively minimizing the risk of unauthorized access due to insider threats or external attacks.

Employing Additional Security Measures for Trade Secrets and Sensitive Data

To further bolster the security of trade secrets and sensitive information, additional layers of protection must be put in place. A critical step is the adoption of multi-factor authentication (MFA) and strong password policies. MFA adds an extra verification step, ensuring that even if one credential is compromised, unauthorized entry is still blocked. Strong password policies, on the other hand, discourage the use of easily guessable passwords, thwarting potential attacks.

A zero-trust approach to data security is another essential practice, where trust is never assumed, and verification is always required. This methodology assumes that every user, even those within the network, could potentially pose a security risk and therefore, must be authenticated and authorized to access specific data or systems.

Moreover, leveraging an HTTPS proxy server enhances security by encrypting sensitive data such as credit card information and personal details before they travel through the network. This ensures that even if data is intercepted, it cannot be read without the proper decryption keys.

The principles of data security and privacy laws, such as General Data Protection Regulation (GDPR), must also be adhered to meticulously. Regular database backups are crucial for maintaining data integrity and ensuring business continuity in the face of cyber threats such as ransomware or data corruption.

Establishing Data Encryption Protocols

Establishing robust data encryption protocols is a non-negotiable aspect of comprehensive database security strategy. Whether it is personal information, intellectual property, or financial records, encryption ensures that data is transformed into a format that is unreadable without the corresponding decryption key. This practice secures data both at rest and in transit—guarding it against unauthorized access.

To maintain effective encryption standards, it is vital to implement the latest encryption algorithms and update them regularly. This proactive approach stays ahead of cybercriminals’ evolving techniques and leverages advanced technology to secure data.

Using solutions like the Encrypting File System (EFS) on Windows platforms allows organizations to specify which users can access encrypted files. It’s a potent defense against both external cyber threats and malicious insider activity.

Summarily, these encryption measures provide a solid defense, ensuring that, in the event of a security breach, the data remains inaccessible to unauthorized individuals— protecting not only organizational assets but also preserving customer trust and compliance with data protection laws. Implementing and rigorously maintaining data encryption protocols is imperative in today’s cyber landscape to safeguard valuable and sensitive information from sophisticated threats.

SQL Server Consulting Services: Maximizing Your Database Performance and Security

As your company becomes increasingly data-driven and you initiate more database projects, your Microsoft SQL Server environment inevitably increases in size and complexity—and so does the trouble a faltering, crashed or insecure database can potentially cause. 

Degraded performance, malfunctioning SQL processes, corrupted data sets, and other SQL Server challenges demand immediate, expert attention. Having a SQL Server consulting team on speed-dial can get your database back on track in short order. Besides emergency services, other SQL Server consulting services that growing companies often eventually need include database health checks, database performance tuning, and database security vulnerability assessments. 

When it comes to your mission-critical SQL Server infrastructure, you can’t afford to waste time or take chances. You need an SQL Server consulting partner whose DBAs can go beyond routine database management to quickly identify and fix the root causes of problems, as well as proactively optimize and enhance your SQL Server environment to prevent future issues. This approach often leads to the best cost/performance equation, especially when your business runs on data.

Securing Your Database: The Importance of SQL Server Audit to Safeguard CUI

Securing Your Database: The Importance of SQL Server Audit to Safeguard CUI

Businesses that handle Controlled Unclassified Information (CUI) or other sensitive data need to comply with applicable information security and privacy regulations to minimize the risk of a data breach, data loss, and other threats to data confidentiality, integrity, and availability. This generally includes regularly or continuously monitoring and auditing all the activities taking place in your Microsoft SQL Server environment. 

To help automate this critical monitoring process, Microsoft provides SQL Server Audit, a tool built into SQL Server that can read database transaction logs to provide information about data and object changes affecting the database. By keeping tabs on how a database is being used, DBAs or security teams can spot suspicious actions that could indicate a potential incident, such as a data breach or cyber attack. 

How SQL Server Audit Works

SQL Server Audit lets you track and analyze events taking place on Microsoft SQL servers to reveal potential vulnerabilities and threats to CUI. It enables you to log all changes to the server settings, as well as record all server activities, in a special database table.

For example, you can check SQL Server Audit data for suspicious log events that point to unauthorized network access. Other activities you can log with SQL Server Audit include:

  • Insert, update, and delete attempts to the server table
  • Connection and login attempts, including both, failed and successful logins
  • Database object access attempts
  • Database management activities
  • Admins and other users who connected to the database engine
  • Creating new logins and databases

You can choose from among several levels of auditing with the SQL Server Audit tool, depending on your specific compliance requirements (e.g., compliance with CMMC Level 2 versus CMMC Level 3). You can create server audits to log server-level events, and/or database audits for database-level events. 

SQL Server Audit Benefits

The overall goal of SQL Server audits is to track how database records are used, who accessed them, and when. This data can help you comply with data protection and privacy regulations, including those governing CUI on non-government systems. It can also improve your information security and incident response—the ability to prevent, detect and contain an attack or data breach impacting your database.

Database auditing also improves your confidence in the accuracy, consistency, and completeness of your data for analytics purposes. Finally, it helps you chart a path of continuous improvement by uncovering problems with your database security, administration, and/or monitoring.

Most common SQL Server Audit levels to protect CUI

Guidance on safeguarding CUI generally recommends implementing either of two SQL Server Audit levels as part of your SQL database audit program: C2 Audit or Common Criteria Compliance. These are the most widely used international standards for SQL auditing.

C2 Audit records data beyond the SQL Server, such as who triggered what events in which database, the event type, the server name, and the event outcome. To get started, you assign an audit ID to each group of related processes starting at login. System calls that these processes perform are thereafter logged with that audit ID. Examples include calls to open or close files, calls to change directories, and failed or successful login attempts.

Common Criteria Compliance replaces C2 Audit processes in many compliance frameworks. This approach uses Extended Events (superseding SQL Trace) to gather audit event details. To residually protect CUI, you can filter specific events out of the trace and subsequently use them in applications that manage SQL Server. Note that Common Criteria Compliance can impact SQL Server performance and should ordinarily be enabled only if your guidance on safeguarding CUI mandates it.

Key SQL Server Audit actions to protect CUI

These are some of the most critical SQL Server events to log for most organizations:

  1. Failed login attempts. This data is vital to identify attempted or successful attacks on your database.
  2. Role member changes. This tells you when a login is added or removed from a server or database role, so you can track your privileged users. and know if an unauthorized user was added.
  3. Database user changes. Like with role member changes, this event tells you when users are created, changed, or deleted from a database so you know who has access within a SQL Server instance.
  4. Database object adds/deletions/changes. While this can create bulky audit logs, guidance on safeguarding CUI frequently mandates it.
  5. AUDIT_CHANGE_GROUP. Logging this event lets you identify when a user is altering or disabling your audit logs to “cover their tracks,” and is often required in audit guidance on safeguarding CUI. Or, this event may just alert you if a DBA disables auditing to temporarily improve SQL Server performance and forgets to re-enable it. 

It’s important to carefully choose the SQL Server events you want to audit based on compliance requirements, so you don’t need to filter unnecessary data. However, it’s important to log unsuccessful as well as successful events, as failures are a top way to spot attacks in progress and identify abuse of privileges.

Guidance on Safeguarding CUI Data: Next steps

Most orgs that handle CUI or other sensitive data are subject to one or more regulations like NIST 800-171, the Cybersecurity Maturity Model Certification (CMMC), HIPAA, Sarbanes-Oxley (SOX), PCI-DSS, etc. The inability to pass a compliance audit puts you at significant risk of fines, legal sanctions, or potentially even criminal prosecution under the US Department of Justice’s False Claims Act.

A database vulnerability assessment performed by Buda Consulting experts will identify any compliance issues with your database environment. This will provide the guidance on safeguarding CUI and other sensitive data that you need to achieve—and demonstrate—compliance to regulators and other stakeholders.

Oracle SQL Firewall: A New Feature That Blocks Top Database Attacks in Real-Time

Oracle SQL Firewall: A New Feature That Blocks Top Database Attacks in Real-Time

Oracle 23c introduces a very powerful and easy-to-use database security feature that many users will want to try, especially for web application workloads. Called Oracle SQL Firewall, it offers real-time protection from within the database kernel against both external and insider SQL injection attacks, credential attacks, and other top threats. 

Oracle SQL Firewall should be a huge help in reducing the risk of successful cyber-attacks on sensitive databases. For example, vulnerability to SQL injection due to improperly sanitized inputs is currently ranked as the #3 most common web application security weakness overall in the latest OWASP Top 10. This tool effectively eliminates SQL injection as a threat wherever it is deployed.

SQL Firewall is intended for use in any Oracle Database deployment, including on-premises, cloud-based, multitenant, clustered, etc. It is compatible with other Oracle security features like Transparent Data Encryption (TDE), Oracle Database Vault, and database auditing.

How Oracle SQL Firewall works

SQL Firewall provides rock-solid, real-time protection against some of the most common database attacks by restricting database access to only authorized SQL statements or connections. Because SQL Firewall is embedded in the Oracle database, hackers cannot bypass it. It inspects all SQL statements, whether local or network-based, and whether encrypted or unencrypted. It analyzes the SQL, any stored procedures, and related database objects. 

The new tool works by monitoring and blocking unauthorized SQL statements before they can execute. To use it, you first capture, review, and build a list of permitted or approved SQL statements that a typical application user would run. These form the basis of an allow-list of permitted actions, akin to a whitelist. 

You can also specify session context data like client IP address, operating system user, or program type on the allow-list to preemptively block database connections associated with credential-based attacks. This includes mitigating the risk of stolen or misused credentials for application service accounts.

Once enabled, Oracle SQL Firewall inspects all incoming SQL statements. Any unexpected SQL can be logged to a violations list and/or blocked from executing. Though the names are similar, Oracle SQL Firewall is much simpler architecturally than the longstanding Oracle Database Firewall (Audit Vault and Database Firewall or AVDF) system. You can configure the new SQL firewall at the root level or the pluggable database (PDB) level.

Is there a downside to using Oracle SQL Firewall?

In part because it is still so new, Oracle SQL Firewall performance data is not widely reported online. Transaction throughput is vitally important for many applications, so it’s possible that SQL Firewall would create unacceptable overhead even if it were minimal. The good news is that “before and after” performance testing in your environment should be straightforward using best-practice testing techniques.

Oracle SQL Firewall administrative security is robust and logically integrated with other Oracle Database admin security, so it does not introduce new security risks. For example, only the SQL_FIREWALL_ADMIN role can administer the tool or query the views associated with it. SQL Firewall metadata is stored in dictionary tables in the SYS schema, which rely on dictionary protection like other such tables in SYS.

Who should use Oracle SQL Firewall?

For any business that needs to improve application security, such as for compliance with US government supply chain regulations or as part of a Zero Trust initiative, Oracle SQL Firewall could be a good choice. It could prove especially useful in DevOps environments due to its minimal impact on application development and testing timelines

What’s next?

A goal for this blog post is to encourage organizations using Oracle 23c to implement SQL Firewall. It is a low-effort way to improve application and database security and significantly reduce information security risk associated with the sensitive data it protects.

The Ultimate Oracle Database Security Assessment Checklist for 2023

The Ultimate Oracle Database Security Assessment Checklist for 2023

They are two simple words, but they are two of the most feared words in business: Data Breach! When companies lose their data, they also lose stakeholder trust and the ability to conduct “business as usual.”

One common security gap is that many companies focus on network security while falling short on database security. Your network is important and should be secured, but it exists to move your data—the lifeblood of your business. 

To help you focus on safeguarding your database in 2023, here is an Oracle database security assessment checklist. These are some of the best practices and controls you can put in place to secure and protect your data.

Key Oracle Database Security Assessment Questions

When many people think about security, it is usually in a general way. They want security, but don’t really define what security looks like. Here are some Oracle database security assessment questions to help you focus your attention on database security.

Are You Using Built-in Oracle Security Features?

Your Oracle database has many security features built in. These can be the first line of defense for your entire database. Many of these features are free and don’t require subscriptions, but are part of your database package.

Do You Have a Current User List?

A database should have a list of privileged users and over-privileged users. This list should show who can do what with the database. This list must stay current as a level of protection and accountability for your company.

Who Is Overseeing Oracle Security Updates?

Oracle often releases security updates, patches, and fixes to help ensure your data stays protected. With the speed of business today, these can be overlooked. You should have someone who makes sure these fixes are implemented immediately. 

Are You Conducting Regular Database Audits?

Database auditing is how administrators review their users’ actions. They do this to see who is accessing the database. This helps ensure that only people who are supposed to access the database are doing so. Database auditing tools can also automatically identify and report on a wide spectrum of vulnerabilities including misconfigurations, missed security patches, use of default or weak passwords, and much more.

What Is Your Password Policy?

Passwords must be actively maintained in accordance with current best practices, or they can become an easy entryway into databases. You must make sure that there aren’t any default, weak, easily guessable, compromised, or non-expiring passwords with access to the system.

Are You Using the CIS Benchmark for Oracle?

The Center for Internet Security (CIS) is a nonprofit that provides “benchmarks”—configuration guides—to help businesses assess and improve the security of specific applications or systems. CIS has an Oracle database benchmark that specifies Oracle-specific configuration settings to mitigate known vulnerabilities and harden your database against attacks. CIS benchmarks also offer a prescriptive, proven approach to compliance with cybersecurity frameworks like NIST 800-171, ISO 27001, and CMMC. 

Using the Oracle Database Security Assessment Tool

To help users have safer databases, Oracle developed the Database Security Assessment Tool (DBSAT). The DBSAT is a free tool that Oracle users can implement, which acts as a database security guide.

DBSAT will scan a database and give you a profile in different formats that helps you see the state of your security. The formats you can choose from include HTML, SLS, TEXT, or JSON. This makes the information quick and easy to digest.

The tool will show you some of the security risks that you currently have in the system. It will then recommend relevant products and features of the system you can use to help stop the risks.

The DBSAT focuses on three specific core areas with its security assessment:

1. The General Security Configuration of Your Database 

The DBSAT can perform a scan to make sure you are minimizing database risk. It will look for missing security patches that you can implement. It will also check to see if you are using encryption auditing within your system.

2. Users and Their Entitlements

One of the main features of the DBSAT is its focus on your users and how they are accessing your system. It will identify your privileged users and show you what areas they can access, plus any areas they are accessing but shouldn’t be.

3. Identifying Sensitive Data in Your Database

The DBSAT will help you stay in compliance with regulations from PCI-DSS to HIPAA to GLBA to GDPR by focusing on your sensitive data. It will help you identify your sensitive data and recognize how it should be treated. This also helps you develop healthy database auditing processes.

Using DBSAT Guidance

DBSAT can help you with your security practices by giving you the information you need to implement and enforce strong security for your database. With the many reports it can generate, your database security doesn’t have to be forgotten.

DBSAT helps you understand your user accounts, along with the roles and privileges of each user. This helps you find and fix short-term risks. Plus, it can give you enough information to have a long-term security strategy.

Get a Database Health Check

Just like a person should have a check-up every year, you want to make sure your database gets a regular health check. The recommended approach is to have an unbiased third-party expert come in and review your database configuration and policies.

A trusted database security assessment partner can review your parameters, database maintenance procedures, alert logs, and trace files. They can also help with many other things, like finding your data blocks and identifying invalid objects.

Look for a health check protocol that includes a focused report so you can take action where it is needed most. The report should show you possible problem areas, help prioritize them, and recommend how to address the problems.

Your Oracle Database Partners

As this Oracle database security assessment checklist shows, there is a lot to think about when it comes to database safety. Too often IT staff are so focused on protecting the network, while the database environment is overlooked.
