DevSecOps explained


DevSecOps, or Development, Security, and Operations, is a practice that aims to integrate security and compliance into the software development and delivery process. The goal of DevSecOps is to build, test, and deploy secure software faster and more reliably.

DevSecOps involves adopting a culture of collaboration and communication between developers, security professionals, and operations teams. It also involves using automation and continuous integration/continuous delivery (CI/CD) tools to streamline the software development process and improve the security of the final product.

Some key practices and tools used in DevSecOps include:

  • Version control: Using version control systems such as Git to track and manage code changes.
  • Code review: Conducting peer review of code changes to ensure that they meet security and quality standards.
  • Static analysis: Using static analysis tools to scan source code for vulnerabilities and security issues.
  • Testing: Using automated testing tools to validate the security and functionality of code changes.
  • Deployment automation: Using CI/CD tools to automate the build, test, and deployment process.
  • Monitoring: Using monitoring tools to track the performance and security of the software in production.

By adopting a DevSecOps approach, organizations can improve the security and compliance of their software, while also speeding up the development and delivery process.

Here is an example of a Jenkinsfile that defines a Jenkins job to build and publish a website:

pipeline { agent { docker { image ‘node:8’ } } stages { stage(‘Checkout’) { steps { checkout scm } } stage(‘Install dependencies’) { steps { sh ‘npm install’ } } stage(‘Build’) { steps { sh ‘npm run build’ } } stage(‘Test’) { steps { sh ‘npm test’ } } stage(‘Scan for vulnerabilities’) { steps { script { def scanner = containers.create( ‘aquasec/trivy:latest’, ‘trivy –exit-code 1 –severity CRITICAL,HIGH –no-progress –format json package.json’, envVars: [ ‘CI’: ‘true’, ‘GITHUB_TOKEN’: credentials(‘GITHUB_TOKEN’) ] ) scanner.start() def vulnerabilities = readJSON(text: scanner.getLog()) if (vulnerabilities.size() > 0) { error “Vulnerabilities found: ${vulnerabilities}” } } } } stage(‘Deploy’) { steps { sh ‘npm run deploy’ } } } }
