Overview

 

In today’s fast-paced software development landscape, security must be integrated at every stage of the SDLC to proactively identify misconfigurations, vulnerabilities, secrets, and other risks, minimizing potential threats early in the process. This article demonstrates how Prisma Cloud seamlessly integrates into the entire SDLC (from early development in the IDE (Visual Studio Code), through version control (GitHub) and PR scanning, to CI/CD pipelines (GitHub Actions) and securing code post-commit). By adopting a shift-left approach, Prisma Cloud empowers developers to catch security risks early, ensuring robust, secure code without slowing down development.


Key Phases:
  1. Early Security Awareness: IDE Integration with Prisma Cloud in VS Code.

  2. Securing Version Control: PR/MR Scanning in GitHub.

  3. Continuous Security Validation: CI/CD Integration with GitHub Actions.

  4. Securing Code Post-Commit: Automated Fixes and Ongoing Monitoring with Prisma Cloud in the SDLC.

 

With Prisma Cloud’s seamless integration into core development tools, security is embedded directly into your workflow—catching misconfigurations, vulnerabilities, secrets, and other risks early, all while maintaining fast, agile development practices.

 

1. Early Security Awareness: IDE Integration with Prisma Cloud in VS Code

 

The journey to secure code begins with IDE (VS Code), where developers write and test their code. At this stage, Prisma Cloud integrates directly into VS Code to provide real-time security scanning and analysis.

 

Key Actions:

  • Static Code Analysis: Prisma Cloud scans the code for vulnerabilities, misconfigurations, and security risks directly within the VS Code IDE.

  • Real-Time Alerts: As developers write code, they receive immediate feedback on potential vulnerabilities, enabling quick remediation.

  • Seamless IDE Integration: Prisma Cloud integrates with VS Code, maintaining an uninterrupted development experience while ensuring that security is embedded from the very first line of code.

 

By identifying and addressing security issues early, developers can ensure the codebase is secure before committing changes.

Demonstration Workflow:

 

Install Prisma Cloud Extension:

  • Open VS Code and go to the Extensions view (Ctrl+Shift+X) - Windows, (Cmd+Shift+X) - Mac.

  • Search for Prisma Cloud and click Install.

2. Securing Version Control: PR/MR Scanning in GitHub

 

Once code changes are committed to GitHub (with the repository named secure-shift-left), it enters the Pull Request (PR) or Merge Request (MR) phase. At this point, Prisma Cloud automatically scans the PR/MR submissions to detect vulnerabilities before merging the code into the main branch.

 

Key Actions:

  • Comprehensive Code Review: Prisma Cloud scans the changes in pull requests and merge requests, checking for security issues that might have been missed earlier.

  • Security Gatekeeping: Just like a quality assurance checkpoint, Prisma Cloud prevents insecure or flawed code from being merged into the main codebase. (Enforcement Rules)

  • Enforcing Secure Development Practices: Prisma Cloud helps reinforce a security-first mindset across the development team by ensuring that security checks are automated during the PR/MR process.

 

This step ensures that only secure code progresses into the shared codebase, minimizing risks in the project.

 

Demonstration Workflow:

  • Resource: aws_instance.fic-02-org-broccoli.

  • Misconfiguration Detected: Same IMDSv1 enabled instead of IMDSv2 (Instance Metadata Service Version 2) (not fixed in the IDE).

  • Action: Prisma Cloud detects this misconfiguration during the PR scan in GitHub and blocks the merge to the main branch. The developer is prompted to fix the misconfiguration before merging the code.

 

Configure Branch Protection Rules:

  • Set up branch protection rules in GitHub to fail builds if a scan step fails.

Figure 12: Prisma-Cloud-DevSecOps_PaloAltoNetworks

 

  • Set Severity Threshold - Enforcement Rules

    • To set the desired severity level (e.g., Critical, High), drag the Comments Bot threshold rule.  

    • The "hard-fail level" defines the threshold for failing a pull request (PR) scan conducted by Prisma Cloud.

Figure 13: Enforcement-Rules_PaloAltoNetworks

 

Trigger PR Scan:

  • When a pull request (PR) is created or updated, Prisma Cloud automatically scans. 

 

 
unnamed.jpg

Figure 14: Prisma-Cloud-analysis_PaloAltoNetworks

 

View PR Scan Results:

  • Errors found by the scan will be displayed as PR comments within the pull request.

Figure 16: How-to-fix_PaloAltoNetworks

 

  • If any findings or issues meet or exceed the defined threshold, the PR scan will fail. With branch protection rules enabled, the Prisma Cloud DevSecOps status check will fail, preventing the merge into the default branch. This serves as the first line of defense in a Shift-Left strategy, ensuring that security issues are identified and addressed before code is merged.

3. Continuous Security Validation: CI/CD with GitHub Actions

 

In the CI/CD pipeline powered by GitHub Actions, Prisma Cloud performs security scans at each stage of the automated build and deployment process. These scans help ensure that only secure code is deployed to production, following the shift-left philosophy of proactive security.

 

Key Actions:

  • Automated Security Validation: Every new code build triggered in GitHub Actions is automatically scanned for vulnerabilities, ensuring only secure code is deployed.

  • Preventing Vulnerable Code from Reaching Production: Prisma Cloud integrates into the CI/CD pipeline to enforce security policies that prevent insecure code from being deployed to production.

  • Pipeline Hardening: GitHub Actions configurations are hardened with security best practices, helping ensure that the pipeline itself remains secure from potential vulnerabilities or attacks.

 

By incorporating Prisma Cloud into the GitHub Actions workflow, security is continuously enforced, and vulnerabilities are caught early, preventing the deployment of insecure code.

 

Demonstration Workflow:

  • Resource: aws_instance.fic-org-broccoli.

  • Misconfiguration Detected: Same IMDSv1 vulnerability (not fixed in the PR).

  • Action: Prisma Cloud detects the issue during the CI/CD pipeline run. The deployment is blocked.

4. Securing Code Post-Commit: Automated Fixes and Ongoing Monitoring with Prisma Cloud in the SDLC

 

Prisma Cloud automates security scans on the default branch of code repositories to detect vulnerabilities, misconfigurations, and compliance issues throughout the SDLC. With Auto Fix and automated Pull Request (PR) creation, Prisma Cloud streamlines the identification and resolution of security risks, reducing time and effort while ensuring code remains secure at every stage.

 

Demonstration Workflow:

  • Resources: aws_instance.fic-org-broccoli, aws_instance.fic-02-org-broccoli.

  • Misconfiguration Detected: Same  IMDSv1 enabled instead of IMDSv2 (Instance Metadata Service Version 2) (not fixed in the PR).

  • Action: Prisma Cloud opens a pull request to apply the required fixes (e.g., setting http_endpoint = "required") to the affected resources. This ensures that misconfigurations are remediated, even after code is already live.

 

Access Scan Results in Prisma Cloud Projects:

  • Suggested fix: Prisma Cloud will often provide an automated fix recommendation for common issues.
