Crafting security-focused Bash scripts for DevSecOps
In this section, we’ll review the code for a Bash scanner script that we’ll integrate into the CI/CD pipeline. First, I’ll create and review the scanner script. Then I’ll demonstrate how to integrate it into the pipeline for automated scanning.
Creating the scan script
Creating secure and maintainable Bash scripts requires careful attention to defensive coding practices, proper error handling, and thorough logging. Let’s build a security scanning script that leverages our DevSecOps environment to demonstrate these principles.
This script can be found in GitHub as ch16_devsecops_scanner.sh. Let’s break down this script into its core components and examine each section.
First, we’ll look at the script initialization and safety measures. The purpose of this section is as follows:
- Enables strict error handling
- Prevents word splitting issues with filenames containing...
