Main tasks

• Use the latest CIS benchmark PDF from https://downloads.cisecurity.org/#/
• Verify IDs numbers.
• Verify texts are correct: Title, Description, Rationale and Remediation.
• Verify Compliance: CIS, CIS_CSC.
• Verify condtion and rules:
  • To Pass.
  • To Fail.

Checks

Syntax and semantic

• a) ID of each policy must be contiguous.
• b) The order and format set in Documentation must be respected.
• c) YML must be valid to avoid errors.

Content

• a) Compare each check with its analogue from CIS Benchmark.
• b) Try to maintain each rule as similar as possible with the Audit section from the CIS check.
• c) Check that the commands provide the expected output.
• d) When a failure is discovered, check similar policies to avoid repetition of the issue.

Unit testing

• a) Output from ossec.log after the SCA scan and a raw output of the result of the checks.
