Key Validation Points and Continuous Security Validation

In modern DevOps pipelines, integrating validation checks and continuous security validation is crucial for maintaining code quality and reducing risks. By embracing a shift-left strategy, teams can detect issues early—saving time and costs while enhancing overall security posture.

Key Validation Points Across the DevOps Lifecycle

At every phase of the DevOps lifecycle, targeted validation steps provide rapid feedback. Early detection through IDE plugins or CI scans prevents defects from propagating downstream.

The image outlines key validation points in a software development process, highlighting stages like feedback, CI, development, and testing, with associated tasks such as code review, vulnerability scanning, and performance testing.

Stage	Validation Checks	Examples
IDE & Pull Requests	Static analysis, peer code review	ESLint, SonarQube, GitHub/GitLab merge requests
Continuous Integration	Automated builds, unit & integration tests	Jenkins, Azure Pipelines, GitLab CI
Development Phase	Security scans, performance testing	OWASP ZAP, SonarCloud, JMeter
Testing Stage	Penetration testing, infrastructure validation	Metasploit, Terraform `validate`, Chef InSpec

Note

Shifting validation left means catching issues in IDEs or CI—before they reach QA or production.

The True Cost of Defects at Each Stage

Defect remediation cost escalates dramatically the later you catch it. Below are industry averages:

The image illustrates the cost of defects at different stages of software development: Coding ($80/defect), Build ($240/defect), QA & Security ($960/defect), and Production ($7,600/defect). It highlights the increasing cost of defects as they progress through the development lifecycle.

Phase	Average Cost per Defect
Coding	$80
Build	$240
QA & Security	$960
Production	$7,600

Note

Fixing a bug during development can cost up to 90% less than patching it in production.

Shifting Security Left

Embedding security early in your DevOps pipeline empowers developers to remediate vulnerabilities before they become critical.

The image illustrates a process of continuous security validation, emphasizing the need to integrate security early in the development cycle to avoid issues before deployment to production. It shows a flow from coding to production with a focus on shifting security left.

Key benefits of shift-left security include:

Early detection of vulnerabilities in code and dependencies
Faster, automated remediation workflows
Significant cost savings per defect

Warning

Delaying security tests until the end of the pipeline can lead to critical vulnerabilities slipping into production.

Continuous Security Validation and Automation

Automating security checks at every commit, build, and release ensures that security keeps pace with rapid deployments.

The image is about "Continuous Security Validation" and highlights the importance of shifting Secure DevOps practices earlier in the development process to reduce costs, and implementing automated tooling to identify issues.

Incorporate these automated security tools:

Static Application Security Testing (SAST)
Dynamic Application Security Testing (DAST)
Software Composition Analysis (SCA)
Runtime Application Self-Protection (RASP)

Note

Combine multiple tools in your CI/CD pipeline to cover code flaws, third-party risks, and runtime threats.
