Secure AI agents against prompt injection, tool abuse, and data exfiltration with defense-in-depth controls.
Run structured AI red team exercises for jailbreak resistance, data exfiltration risk, harmful output controls, and agent tool abuse resilience.
Searches and explores Burp Suite project files (.burp) from the command line. Use when searching response headers or bodies with regex patterns, extracting security audit findings, dumping proxy history or site map data, or analyzing HTTP traffic captured in a Burp project.
Use when assessing security for Python FastAPI applications. Focuses on Pydantic exploitation, dependency injection gaps, OpenAPI exposure, ASGI middleware security, and Python-specific vulnerabilities like template injection and SSRF.
Security assessment methodology for Google Firebase applications, covering Firestore, Realtime Database, Cloud Storage, and Cloud Functions.
Use when testing GraphQL APIs for common vulnerabilities including introspection exploitation, authorization bypasses, batching abuse, and denial of service. Covers endpoint discovery, schema analysis, and exploitation of GraphQL-specific features like federation and directives.

GitHub Advanced Security (GHAS) integrates CodeQL-powered static application security testing directly into the GitHub development workflow. CodeQL treats code as data, enabling semantic analysis that identifies security vulnerabilities such as SQL injection, cross-site scripting, buffer overflows, and authentication flaws with significantly fewer false positives than traditional pattern-matching scanners. GHAS encompasses code scanning, secret scanning, dependency review, and Dependabot alerts to provide a comprehensive security posture for repositories.
CodeQL compiles source code into a queryable database, then executes security-focused queries against that database. The query suites ship with hundreds of checks mapped to CWE identifiers and cover OWASP Top 10, SANS Top 25, and language-specific vulnerability patterns. Custom queries can be authored using the CodeQL query language (QL) to detect organization-specific anti-patterns.
Default Setup enables code scanning with a single click from the repository's Code Security settings. GitHub automatically determines the languages present, selects appropriate query suites, and configures scanning triggers. This approach requires no workflow file and is ideal for rapid onboarding.
Advanced Setup generates a .github/workflows/codeql.yml workflow file that can be customized. Teams control scheduling, language matrices, build commands for compiled languages, additional query packs, and integration with third-party SARIF producers. Advanced setup is required when custom build steps, monorepo configurations, or private query packs are needed.
For enterprises managing hundreds of repositories, GHAS supports configuring code scanning at scale using the organization-level security overview. Administrators can enable default setup across all eligible repositories, define custom security configurations, and monitor adoption through the security coverage dashboard.
Create .github/workflows/codeql-analysis.yml:

Install organization-specific query packs by referencing them in the workflow:
- name: Initialize CodeQL

.github/dependabot.yml for automated dependency version updates| Suite | Description | Use Case |
|---|---|---|
default | High-confidence security queries | Production scanning with minimal false positives |
security-extended | Broader security queries including lower-severity findings | Comprehensive security coverage |
security-and-quality | Security plus code quality queries | Teams wanting both security and maintainability checks |
| Custom packs | Organization-authored queries | Detecting internal anti-patterns and compliance violations |
GHAS accepts SARIF (Static Analysis Results Interchange Format) uploads from external tools:
