General Security Audit

This skill provides a comprehensive workflow for identifying security vulnerabilities in the codebase using industry-standard tools.

Prerequisites

Before starting the audit, ensure the following tools are installed:

• trivy (Container and filesystem vulnerability scanner)
• osv-scanner (Google's vulnerability scanner for open-source dependencies)
• trunk (Integrated security and linting platform)

Tool Installation

If any tools are missing, install them using the following commands. If Homebrew (brew) is available, it is the recommended method.

Using Homebrew (macOS/Linux):

brew install trivy osv-scanner trunk

Manual Installation:

• osv-scanner: Installation Guide
• trunk: Installation Guide

Workflow Steps

1. Broad Filesystem Scan (trivy)

Run a filesystem scan to catch vulnerabilities and hard-coded secrets in configuration files, source code, and project structure. By default, trivy fs scans for both vulnerabilities and secrets.

# Scan for vulnerabilities and secrets
trivy fs .

# (Optional) Scan for misconfigurations in IaC and config files
trivy config .

2. Dependency Vulnerability Scan (osv-scanner)

Perform a deep scan of your project's dependencies against the OSV database using the scan source command.

osv-scanner scan source -r .

3. Integrated Security Check (trunk)

Run integrated security checks. trunk check executes all enabled linters. You may need to enable specific security scanners like trivy first.

# Enable trivy if not already enabled
trunk check enable trivy

# Run security checks on modified files
trunk check

# Run on all files
trunk check --all --scope security

Report Format

After running the tools, compile a report in the following structure:

1. Immediate Actions: Fixes for Critical and High vulnerabilities.
2. Follow-up: Mitigation strategies for lower-severity issues.
3. Prevention: Configuration changes to prevent reintroduction.
