SCA Operating System Specific Policies - Phase 3

[TomasTurina]

Description

This issue tracks the development of initial security compliance policies tailored for specific operating systems. The objective is to ensure that the Security Compliance Assessment (SCA) module is equipped with policies that align with the security benchmarks and compliance requirements of each supported OS. This phase will involve writing, validating, and refining policies for various operating systems.

Functional Requirements

• Develop initial security compliance policies for the following operating systems:
  • Amazon Linux 2023
  • Ubuntu 24.04
  • macOS 15 Sequoia
  • Windows 11
• Ensure that each policy aligns with industry best practices and relevant security benchmarks.
• Policies must be compatible with the new agent architecture and execution logic.
• Policies must be validated for accuracy and effectiveness.

Non-Functional Requirements

• Policies must be structured in a way that allows easy maintenance and future expansion.
• The implementation should ensure efficient execution without excessive resource consumption.
• The policies should be documented clearly, including rationale and expected outcomes.

Implementation Restrictions

• Policies should follow the format used in the existing 4.x framework to ensure compatibility.
• Policies must be designed to work within the new agent’s policy execution flow.
• The policies should not introduce breaking changes to existing compliance checks.

Plan

Develop Initial Policies

• Research and define security benchmarks and compliance requirements for each OS.
• Write initial policies based on established security guidelines.
• Validate policies against sample system environments.

Policy Testing and Validation

• Execute policies in test environments for each OS to verify expected behavior.
• Compare results with industry benchmarks to ensure compliance accuracy.
• Optimize policies to minimize false positives and false negatives.

Policy Documentation

• Provide detailed documentation for each policy, including:
  • Purpose and compliance standards addressed.
  • Expected outcomes of each check.
  • Configuration and customization options.
• Ensure policies are properly structured for future updates and expansion.

Final Review and Refinement

• Gather feedback from security experts and stakeholders.
• Make necessary adjustments to improve accuracy and effectiveness.
• Prepare policies for deployment within the new agent framework.
