Rule: Deprecation - Guidelines

These guidelines serve as a reminder set of considerations when recommending the deprecation of a rule.

Documentation and Context

• Description of the reason for deprecation.
• Include any context or historical data supporting the deprecation decision.

Rule Metadata Checks

• deprecated = true added to the rule metadata.
• updated_date should be the date of the PR.

Testing and Validation

• A prior rule tuning occurred for the rule where Deprecated - is prepended to the rule name, and the rule has already been released.
• Rule has be moved to the _deprecated directory.
• Double check gaps potentially or inadvertently introduced.
• Provide evidence that the rule is no longer needed or has been replaced (e.g., alternative rules, updated detection methods).
