How to Automate Vulnerability Scanning in Jenkins/GitHub Actions

Manual security checks are not enough in modern DevOps environments. Applications are deployed frequently, and vulnerabilities can slip through easily.

Automation is the solution.

In this guide, you’ll learn how to automate vulnerability scanning using Jenkins and GitHub Actions.

---

Why Automate Vulnerability Scanning?

• Faster detection
• Continuous monitoring
• Reduced human error

---

Types of Vulnerability Scanning

• SAST
• DAST
• Dependency scanning
• Container scanning

---

Jenkins Setup

Install Jenkins and required plugins.

---

Jenkins Pipeline Example

pipeline {
    agent any

    stages {
        stage('Scan Code') {
            steps {
                echo 'Running SAST scan'
            }
        }
        stage('Scan Dependencies') {
            steps {
                echo 'Scanning dependencies'
            }
        }
    }
}

GitHub Actions Setup

Create workflow:

name: Security Scan

on: [push]

jobs:
  scan:
    runs-on: ubuntu-latest

    steps:
      - uses: actions/checkout@v3
      - name: Run Scan
        run: echo "Scanning"
