Policy Management

Overview

The Policy Management feature provides a Policy as Code approach to security governance. Define your security requirements in YAML or JSON, and CybeDefend will automatically evaluate every scan against your policies.

Hierarchical Policies

Organization → Team → Project hierarchy ensures policies cascade appropriately

Policy as Code

Version-controlled YAML/JSON policies that integrate with your GitOps workflow

Async Evaluation

Non-blocking BullMQ-based worker for fast policy evaluation

Compliance Tracking

Full audit trail and compliance history for governance reporting

Key Features

Policy Hierarchy

Policies are applied in a hierarchical manner, ensuring organizational standards cannot be bypassed:

Organization Policy (highest priority)
    ↓
Team Policy
    ↓
Project Policy (lowest priority)

A policy at a higher level cannot be disabled by a policy at a lower level. Lower-level policies can only add stricter rules.

Automatic Vulnerability Filtering

During policy evaluation, certain vulnerabilities are automatically ignored to focus on active security risks:

Status	Description
`not_exploitable`	Manually reviewed and marked as not posing a security risk
`resolved` / `fixed`	Already fixed in the source code
`ignored` / `accepted_risk`	Risks that have been formally accepted by the organization

Policy Configuration

Policies are defined in YAML format with complete metadata. Here’s a full example:

version: '1.0'
name: 'Production Security Policy'
description: 'Strict security policy for production deployments'
scope: PROJECT  # ORGANIZATION | TEAM | PROJECT
priority: 10    # 1-100 (lower = higher priority)
enabled: true

# For PROJECT scope - specify target projects
projectIds:
  - 550e8400-e29b-41d4-a716-446655440001

rules:
  - name: 'Block critical vulnerabilities'
    type: severity
    operator: eq
    value: CRITICAL
    action: block

  - name: 'Warn on high vulnerabilities'
    type: severity
    operator: eq
    value: HIGH
    action: warn

  - name: 'Block high CVSS scores'
    type: cvss_score
    operator: gt
    value: 9.0
    action: block

# Optional exclusions (max 30)
exclusions:
  - pattern: 'test/**'
    reason: 'Test files are not deployed to production'
  
  - pattern: '**/vendor/**'
    reason: 'Third-party code - tracked separately'
    expirationDate: '2026-06-30T00:00:00Z'

Policies require 1-15 rules and support a maximum of 30 exclusions.

Rule Types

Type	Description	Valid Values
`severity`	Vulnerability severity level	`critical`, `high`, `medium`, `low`, `info`
`cvss_score`	CVSS score (0-10)	Numeric value (e.g., `7.5`, `9.0`)
`cwe_check`	CWE identifier	String (e.g., `CWE-89`, `CWE-79`)
`owasp_category`	OWASP Top 10 category	String (e.g., `A01:2021`, `A03:2021`)
`scanner_type`	Type of scanner	`sast`, `secret`, `sca`, `container`, `iac`, `cicd`
`vulnerability_age_days`	Days since detection	Numeric value
`is_new_vulnerability`	Whether vulnerability is new	Boolean (`true`/`false`)
`branch`	Git branch name (supports glob)	String (e.g., `main`, `feature/*`)
`composite_and`	Combine rules with AND logic	Array of sub-rules
`composite_or`	Combine rules with OR logic	Array of sub-rules

Operators

Operator	Description	Example
`eq`	Equals (exact match)	`severity eq critical`
`neq`	Not equals	`severity neq info`
`gt`	Greater than	`cvss_score gt 7.0`
`lt`	Less than	`vulnerability_age_days lt 30`
`gte`	Greater than or equal	`cvss_score gte 9.0`
`lte`	Less than or equal	`vulnerability_age_days lte 7`
`in`	In list	`severity in [critical, high]`
`not_in`	Not in list	`cwe_check not_in [CWE-1, CWE-2]`

Actions

Action	Description	CI/CD Exit Code
`block`	Blocks the pipeline, creates violation record	`1`
`warn`	Creates violation record, doesn’t block	`0`

Composite Rules

Use composite rules to combine multiple conditions:

AND Logic (All conditions must match)

- name: 'Block Critical on Main Branch'
  type: composite_and
  action: block
  criteria:
    - type: severity
      operator: eq
      value: CRITICAL
    - type: branch
      operator: eq
      value: main

OR Logic (Any condition can match)

- name: 'Block dangerous patterns'
  type: composite_or
  action: block
  criteria:
    - type: cvss_score
      operator: gt
      value: 9.0
    - type: cwe_check
      operator: in
      value: ['CWE-89', 'CWE-78', 'CWE-94']

Exclusions

Exclusions allow you to skip policy evaluation for specific files or patterns:

exclusions:
  - pattern: 'test/**'
    reason: 'Test files are not deployed'  # Required

  - pattern: '**/node_modules/**'
    reason: 'Dependencies tracked via SCA'
    expirationDate: '2026-12-31T00:00:00Z'  # Optional expiration

Pattern matching uses glob patterns:

** matches any number of directories
* matches any characters except /
? matches a single character

Always set expiration dates on exclusions to prevent permanent security gaps.

CI/CD Integration

GitHub Actions

Use the official CybeDefend GitHub Action with policy evaluation enabled:

name: CybeDefend Security Scan with Policy Enforcement

on:
  push:
    branches:
      - main
  pull_request:
    branches:
      - main

jobs:
  scan:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout code
        uses: actions/checkout@v3

      - name: Run CybeDefend Security Scan
        uses: CybeDefend/cybedefend-action@v1
        with:
          token: ${{ secrets.CYBEDEFEND_PAT }}
          project_id: ${{ secrets.CYBEDEFEND_PROJECT_ID }}
          branch: ${{ github.head_ref || github.ref_name }}
          # Policy evaluation options
          policy_check: true
          policy_timeout: 300
          show_policy_vulns: true
          show_all_policy_vulns: false

Policy Evaluation Options

Option	Default	Description
`policy_check`	`true`	Enable/disable policy evaluation after scan
`policy_timeout`	`300`	Timeout in seconds for policy evaluation
`show_policy_vulns`	`true`	Show affected vulnerabilities in output
`show_all_policy_vulns`	`false`	Show all vulnerabilities (no limit)

GitLab CI

Use the CybeDefend CLI directly with policy evaluation:

stages:
  - security

cybedefend-scan:
  stage: security
  image: ghcr.io/cybedefend/cybedefend-cli:v1.0.9
  variables:
    CYBEDEFEND_PAT: $CYBEDEFEND_PAT
    CYBEDEFEND_PROJECT_ID: $CYBEDEFEND_PROJECT_ID
  script:
    # Run scan with policy evaluation (enabled by default)
    - cybedefend scan --dir . --branch $CI_COMMIT_REF_NAME --ci
  rules:
    - if: $CI_PIPELINE_SOURCE == "merge_request_event"
    - if: $CI_COMMIT_BRANCH == "main"

CLI Policy Flags

Flag	Default	Description
`--policy-check`	`true`	Enable/disable policy evaluation
`--policy-timeout`	`300`	Timeout in seconds for evaluation
`--show-policy-vulns`	`true`	Show affected vulnerabilities
`--show-all-policy-vulns`	`false`	Show all vulnerabilities without limit

Example Output

✓ Scan completed successfully
ℹ Checking policy evaluation status...
✓ Policy evaluation completed
ℹ Policy violations found: 2 BLOCK, 1 WARN

⛔ BLOCK Actions:
  ✗ No Critical Vulnerabilities (BLOCK)
    Affected: 3 vulnerabilities
      → [CRITICAL] SQL Injection - src/api/users.ts (L45-48)
        https://us.cybedefend.com/project/xxx/sast/issue/yyy
      → [CRITICAL] Path Traversal - src/utils/file.ts (L12)
        https://us.cybedefend.com/project/xxx/sast/issue/zzz

⚠️ WARN Actions:
  ⚠ Dependency Check (WARN)
    Affected: 1 vulnerability
      → [HIGH] Prototype Pollution - lodash@4.17.15
        https://us.cybedefend.com/project/xxx/sca/issue/aaa

✓ Acknowledged Violations (not blocking):
  ⚠ No High Vulnerabilities (BLOCK)
    ✓ Acknowledged: Risk accepted for legacy code

If any policy has a BLOCK action with violations, the CLI exits with code 1, failing the pipeline. WARN actions are informational only and don’t affect the exit code.

Managing Violations

When a policy violation occurs, you have two options to resolve it:

Change Vulnerability Status

Change the vulnerability status from “open” to “ignored” with a justification. The vulnerability will be excluded from future policy evaluations.

Fix the Vulnerability

Resolve the security issue directly in your source code and re-run the scan. The vulnerability will be marked as “resolved” and excluded from policy evaluations.

Both approaches create an audit trail. Changing status to “ignored” requires a comment explaining the risk acceptance decision.

Best Practices

Start with Warning-Only Mode

When rolling out policies, start with action: warn to understand the impact before switching to action: block.

Use Expiring Exclusions

Always set expiration dates on exclusions to prevent permanent security gaps:

exclusions:
  - pattern: 'src/legacy/**'
    reason: 'Technical debt - scheduled for Q2 refactor'
    expirationDate: '2026-06-30T00:00:00Z'

Layer Policies Appropriately

Organization level: Global security requirements (e.g., no exposed secrets)
Team level: Team-specific standards (e.g., frontend vs backend rules)
Project level: Project-specific exclusions only

Version Control Your Policies

Store policy YAML files in your repository:

repo/
├── .cybedefend/
│   ├── policies/
│   │   ├── sast-policy.yaml
│   │   ├── sca-policy.yaml
│   │   └── secret-policy.yaml
