[Security Solution] Rule domain definition

[xcrzx]

Summary

Currently, we have the rule schema defined in multiple places and contexts, such as rule response, diffable rule, rule upgrade specifiers, etc. This fragmented approach leads to a sub-optimal developer experience and is prone to errors. When a new rule field is added, developers must manually update all locations where rule schemas are defined, which is time-consuming and error-prone.

Proposal:

Explore the possibility of creating a single source of truth for rule schemas.

Key Points:

• Single Configuration File:

  • Create a configuration file that contains comprehensive information about all rule types and their fields.
  • This schema should include details about each field, such as whether it is defaultable, required, diffable, part of rule params or attributes, and so on.

• Code Generation:

  • From this unified rule schema, we could derive or automatically generate various structures, such as rule responses, diffable rules, upgrade payloads, and other necessary structures.

Verify that the approach allows us to achieve

• [ ] Improved Developer Experience: Simplified process of adding new fields by updating a single source of truth.
• [ ] Reduced Errors: Minimized the chances of missing updates in multiple locations by centralizing schema definitions.
• [ ] Enhanced Maintainability: The rule schema is more maintainable and consistent across the entire codebase.
