Teams often scan images for vulnerabilities at every commit for every microservice (e.g., 50 services * 100 commits = 5,000 scans/day). Use image caching and base image rebasing . Do not rebuild the entire Python base image for a code change. Scan the base image weekly; scan the application layer only on code change.
The core objective is to reduce risk without slowing down development teams, providing security teams with visibility, and offering developers an easy, secure path to production. 2. Key Pillars of Tanzu DevSecOps To implement DevSecOps, Tanzu focuses on three main areas: A. Securing the Software Supply Chain DevSecOps in Practice with VMware Tanzu: A Comprehensive
A secure software supply chain ensures that only trusted code reaches your production environment. Tanzu automates this verification process from source to deployment. Container Image Security
Security inside a Tanzu ecosystem extends beyond the build phase into the active runtime environment. Declarative Policy-as-Code
When an operating system or runtime vulnerability is discovered, TBS automatically updates the underlying base image layers without interrupting application code. Use image caching and base image rebasing
A practical Tanzu DevSecOps workflow spans from the developer desktop to live production traffic. Step 1: Code and Source Governance
When an operating system vulnerability (CVE) is discovered in a base image, TBS can "rebase" the application layer onto a patched base layer in seconds, without triggering a full application recompile. III. Declarative Policy Enforcement
The authors do an excellent job of delineating tasks for different roles—developers, architects, and operators—ensuring that the content is relevant regardless of where you sit in the SDLC.
: Access a library of pre-packaged, verified open-source components that are continuously monitored and updated for security. 2. Automating the Secure Supply Chain
Instead of running rigid, sequential CI/CD scripts, Tanzu choreographs independent tools (git repositories, scanners, builders) into a cohesive, reusable pipeline.
