[New Rule] Potential Defense Evasion via Doas

Rule: New - Guidelines

These guidelines serve as a reminder set of considerations when proposing a new rule.

[ ] creation_date matches the date of creation PR initially merged.
[ ] min_stack_version should support the widest stack versions.
[ ] name and description should be descriptive and not include typos.
[ ] query should be inclusive, not overly exclusive, considering performance for diverse environments. Non ecs fields should be added to non-ecs-schema.json if not available in an integration.
[ ] min_stack_comments and min_stack_version should be included if the rule is only compatible starting from a specific stack version.
[ ] index pattern should be neither too specific nor too vague, ensuring it accurately matches the relevant data stream (e.g., use logs-endpoint.process-* for process data).
[ ] integration should align with the index. If the integration is newly introduced, ensure the manifest, schemas, and new_rule.yaml template are updated.
[ ] setup should include the necessary steps to configure the integration.
[ ] note should include any additional information (e.g. Triage and analysis investigation guides, timeline templates).
[ ] tags should be relevant to the threat and align/added to the EXPECTED_RULE_TAGS in the definitions.py file.
[ ] threat, techniques, and subtechniques should map to ATT&CK always if possible.

[ ] building_block_type should be included if the rule is a building block and the rule should be located in the rules_building_block folder.
[ ] bypass_bbr_timing should be included if adding custom lookback timing to the rule.
