A Curated Collection of Writings, Research, and Solutions
Learn what a Common Vulnerabilities and Exposures is, what qualifies, how CVE IDs are assigned by CNAs, why some are rejected, where to find new CVEs, and how CVSS and CWE relate via NVD enrichment for vulnerability management.
Learn what immutable infrastructure is, how it differs from mutable servers, key benefits, real-world examples, tools, challenges, and a practical migration path for modern DevOps teams.
Learn what CI CD is, how CI/CD pipelines work in DevOps, and how teams automate build, testing, delivery, and deployment. See common tools, cloud best practices, security checks, and workflow examples.
Understand environment variables with clear explanations of syntax, OS differences, examples, pseudo-variables, development tool usage, and troubleshooting practices to configure applications reliably across environments.
Learn how to reduce supply chain risk using SBOMs, signed releases, build provenance, policy gates, and secure CI CD practices. Includes practical controls for container images and Kubernetes.
Learn what DevSecOps is, how it differs from DevOps, and how it secures CI/CD, cloud native workloads, and AI driven workflows with principles, best practices, tools, and future trends.
OCI image format guide covering OCI specs, manifest, config, and layer digests. Learn how OCI compares to Docker images, how registries distribute artifacts, and how OCI standardization makes container packaging portable, verifiable, and consistent across environments.
Learn what vulnerability scanning is, how it works, the main types, tools, internal vs external approaches, cloud and CI/CD support, best practices, challenges, and FAQs to strengthen your security posture and reduce cyber risk.
Learn what Linux containers are, how LXC, LXD and Docker work, and why they improve deployment, portability and security. Covers core concepts, runtimes, isolation methods and real-world use cases.
Learn what an image repository is, how it works, how to configure ImageRepository specs, choose the right registry, interpret status fields, and understand key security risks in container image management.
Learn container monitoring for Docker and Kubernetes, including key metrics, logs, tracing, dashboards, alerting, best practices, common challenges, and tool choices for reliable production observability.
Learn how container scanning works, prevents vulnerable images, and how to use tools, best practices, and continuous checks to secure DevSecOps pipelines.
Learn the complete container lifecycle, from image creation to termination. Explore stages, platform differences, monitoring, updates, hooks, and best practices.
Learn what container image security is, how it works, why it matters, the risks involved, how to scan images for vulnerabilities, and the best practices and tools teams use to secure containerized workloads.
Learn what distroless container images are, how they differ from regular images, their key components, security benefits, limitations, and best practices for building, debugging, and running them in production and Kubernetes environments.
Learn how Docker image layers work, how container image layering differs from containers, how caching and base images affect size and performance, and which tools help you inspect, optimise and manage images.
