   • Review Logs and Reports: Analyze security logs, incident reports, and previous audit findings.

3. Vulnerability Assessment:

   • Automated Scanning: Use tools like Nessus, OpenVAS, or Qualys to scan for vulnerabilities in systems and networks.
   • Manual Testing: Perform manual checks to identify misconfigurations, weak passwords, and unpatched systems.
   • Risk Analysis: Evaluate the potential impact and likelihood of identified vulnerabilities.

4. Configuration Review:

   • System Configuration: Check systems against security benchmarks (e.g., CIS Benchmarks) to ensure proper configuration.
   • Access Controls: Verify that access controls are properly implemented, limiting access to authorized users only.
   • Patch Management: Review the process for applying security patches and updates.

5. Access Control Review:

   • User Accounts: Audit user accounts to ensure they are necessary, active, and have appropriate permissions.

   • Recommendations: Provide actionable recommendations to address the identified issues.
   • Executive Summary: Include a high-level summary for stakeholders outlining the key findings and suggested actions.

7. Follow-Up:

   • Action Plan: Develop an action plan based on the audit recommendations and assign responsibilities.
