🤔 Secure SDLC DevSecOps framework
Salute,
I think today we will look at the concept of technical implementation of DevSecOps. Thus, we will collect the picture from previous posts and go further into the interesting things 🙃
SSDLC - Secure Software Development Lifecycle: a development methodology where security is not a separate testing phase, but is built into every stage of development. Well, we’ve gathered here for this reason - that’s why we’re discussing it head on.
I think it's cool to look at the complex technical structure of the process. The type of process itself describes precisely automated control of operations. You and I are so focused on Shift-Left Security and Continuous Security Validation. Look at the diagram and then compare it with the description so that you can understand more clearly how to do it according to the canon 🥶
Quality Gate
• Pre-merge: Code Review
• Post-merge: Security Checks
• Pre-deploy: Quality Gate Decision
• Post-deploy: Runtime Monitoring
Steps
1 - Request to change functionality
• Threat Modeling for new features
• Security Requirements Gathering and Definition
• Risk Analyzes at the feature level
2 - Merge Request to Reviewers Approve (Diamond)
• Security-focused code review checklist
• Stack-specific patterns
• Pre-commit hooks
• Linting security rules
• License compliance
3 - Tracking issues, subsequent AppSec profiling
• Library versions
• Compliance requirements
• Vulnerability baseline
•Security exceptions
• Criticality level
• ENV
4 - Results from analyzers and sending mapping
• Vulnerabilities
• Business logic
•Hardcoded secrets
• Transitive dependencies
• License compliance
• Outdated libraries
• Misconfigurations
5 - Vulnerability Management System/ Platform (integration with RFC - delivery attributes)
• Deduplication
• Summary Base Score
• Business Impact Assessment
• Exploitability Score
6 - Making a decision on delivery (Decision point)

})

10 - Functional Acceptance Testing
11 - User Acceptance Testing
12 - Post Actions CI/CD
Overall: the diagram represents a mature DevSecOps process with good security integration
• Shift-Left Security implemented through early scanning
• Quality Gate as a central control point
• Defense in Depth through multiple security layers
• Process automation
