[Security Solution] Users can Customize Prebuilt Detection Rules: Milestone 3

[banderror]

Epic: https://github.com/elastic/security-team/issues/1974 (internal)
Milestones: << • >>

Status: In development.

Summary

Milestone 3: Add support for customizing prebuilt rules. Extend the rule upgrade workflow with full support for 3-way diffs and conflict resolution.

This meta ticket is created to simplify tracking of various tickets related to the epic, and to make this public information so our users can track the progress.

User-facing outcomes:

• Users can click “edit” button for prebuilt rules and customise any field in the same editing interface as the custom rules
• User can filter rules in the rule management page by custom/customised/Elastic
• User can see if the rule was customised on the rule details page
• If the prebuilt rule is customised and update comes in:
  • User can see the current version and update and compare per field
  • They are able to edit the final field versions before finalising the update
  • If the rule type changes - they can only accept the incoming changes
• Prebuilt rules can be exported and imported

Useful info:

• RFC: Prebuilt Rules Customization - a new technical design document describing in detail how prebuilt rule customization should work and affect other existing features.
• Prebuilt Rules Customization Technical Design - an older document from Milestone 1.

  • API endpoint for the package with prebuilt rules #187647
  • Smart limits for the package with prebuilt rules #187645
  • Splitting the package with prebuilt rules #187648
  • Alternative mechanism for distributing prebuilt rules #187649
  • Detection rule migration mechanism #187651
  • DetectionRulesClient refactoring. Part 3 #187656
  • Implement query fields diff algorithm #187658
  • Implement data source fields diff algorithm #187659
  • Implement MITRE ATT&CK® field diff algorithm #187660
  • Calculate and save ruleSource.isCustomized in bulk edit API #187706

  • Implement UI for updating prebuilt rule to a new rule type #180395
  • Replace PATCH logic with PUT when upgrading rules #180195
• Assigned 8.16 candidate and 8.17 candidate labels to all the tickets in Milestone 3.
• Moved the tickets that we can postpone until later to Milestone 4.
