Performing Container Security Scanning with Trivy

Overview

Trivy is an open-source security scanner by Aqua Security that detects vulnerabilities in OS packages and language-specific dependencies, infrastructure-as-code misconfigurations, exposed secrets, and software license issues across container images, filesystems, Git repositories, and Kubernetes clusters. Trivy generates Software Bill of Materials (SBOM) in CycloneDX and SPDX formats for supply chain transparency. This skill covers comprehensive container image scanning, CI/CD pipeline integration, Kubernetes operator deployment, and scan result triage for security operations.

When to Use

Trigger phrases:

• "performing container security scanning with trivy"

• "Scan container images, filesystems, and Kubernetes manifests for vulnerabilities"

• When conducting security assessments that involve performing container security scanning with trivy

• When following incident response procedures for related security events

• When performing scheduled security testing or auditing activities

• When validating security controls through hands-on testing

Prerequisites

• Trivy v0.50+ installed (binary, Docker, or Homebrew)
• Docker daemon access for local image scanning
• Container registry credentials for remote image scanning
• CI/CD platform (GitHub Actions, GitLab CI, Jenkins) for pipeline integration
• Kubernetes cluster for Trivy Operator deployment (optional)

Steps

# Example: IOC detection
import re

IOC_PATTERNS = {
    "ip": r"\b(?:\d{1,3}\.){3}\d{1,3}\b",
    "domain": r"\b[a-z0-9-]+\.[a-z]{2,}\b",
    "hash_md5": r"\b[a-f0-9]{32}\b",
    "hash_sha256": r"\b[a-f0-9]{64}\b",
}

def extract_iocs(text: str) -> dict:
    return {k: re.findall(v, text) for k, v in IOC_PATTERNS.items()}
