What is the most effective way to ensure your database security audits cover all relevant risks and threats?

1 Define your scope and objectives

Before you start your audit, you need to define what you want to achieve and what you want to examine. Your scope and objectives should be aligned with your business goals, compliance requirements, and risk appetite. For example, you may want to audit your database performance, availability, backup and recovery, encryption, authentication, authorization, or logging. You may also want to focus on specific databases that handle sensitive or critical data, or that have been recently changed or migrated. Your scope and objectives should be clear, realistic, and measurable.

2 Choose your audit tools and methods

Depending on your scope and objectives, you may need to use different tools and methods to conduct your audit. These could include database scanners, queries, audits, and reviews. Database scanners can help you automate and standardize your audit process, while queries can verify and validate security settings. Audits can monitor activity and analyze behavior, while reviews can assess design or architecture. However, each of these tools and methods may have limitations or drawbacks. Thus, you may need to use a combination of them to achieve an accurate audit. Additionally, consider the compatibility, scalability, and reliability of your tools and methods.

3 Follow a standard framework or guideline

To ensure that your audit is consistent, systematic, and complete, you should follow a standard framework or guideline that covers the key aspects of database security. Examples of such frameworks or guidelines include ISO/IEC 27001, which is an international standard that provides a comprehensive and risk-based approach to managing information security, including database security. NIST SP 800-53 is a publication by the National Institute of Standards and Technology (NIST) that provides a catalog of security and privacy controls for federal information systems and organizations. Additionally, CIS Benchmarks provide detailed and actionable recommendations for configuring and hardening databases. It is important to choose a framework or guideline that suits your needs, context, and compliance obligations, and customize it to your specific database environment and requirements.

4 Document and report your findings and recommendations

Once you've conducted your audit, it's important to document and report your findings and recommendations. Your documentation and report should be clear, concise, and consistent. It should include the scope and objectives of your audit, the tools and methods used, the framework or guideline followed, the data and evidence collected, the risks and threats identified, the gaps and issues found, the recommendations and actions proposed, as well as the prioritization and categorization of your findings. Be sure to communicate and share your documentation and report with relevant stakeholders such as management, team members, or clients.

5 Implement and monitor your recommendations and actions

The final step of your audit is to implement and monitor your recommendations and actions. You should assign roles and responsibilities, define timelines and milestones, track and measure progress, evaluate and review effectiveness and efficiency, and update and revise your recommendations as needed. Additionally, it's important to conduct periodic or continuous database security audits to ensure that your databases remain secure and compliant.
