Linux log files are text-based records that capture system events, application activities, and user actions. They're stored primarily in the /var/log directory and provide essential information for debugging issues, monitoring system health, and maintaining security. This guide covers the most important Linux log files and a few detailed techniques for reading and analyzing them.

The Cybersecurity Maturity Model Certification, or CMMC for short, is a security framework for protecting Controlled Unclassified Information (CUI) in non-federal systems and organizations. The CMMC compliance requirements map to the set of controls laid out in the NIST SP 800-171 Rev 2 and NIST SP 800-172 families.

Explore how Docker and Cloudsmith help secure the software supply chain with SBOMs, signatures, provenance, and hardened images - enabling end-to-end visibility and trust without slowing development.

Pulling Docker images from private registries for containerised applications presents a security challenge. It requires authentication management, network access, and trust across distributed systems. Credentials must be securely handled and rotated, and image pulls can break due to network restrictions or expired tokens. All of this makes deployment and security harder.

One of the more overlooked yet critical vulnerabilities highlighted in the OWASP Top 10 for CI/CD Security Risks is Insufficient PBAC (Pipeline-Based Access Controls). Let’s unpack what PBAC is, why it's essential, and how you can leverage modern access control tools like Open Policy Agent (OPA) and Rego to mitigate these risks effectively.

MinIO is a high-performance, S3-compatible object storage server built for cloud-native applications. It’s open-source, lightweight, and incredibly fast which makes it a solution for developers who need to store and serve unstructured data like images, logs, or backups. Whether you’re building a self-hosted alternative to Amazon S3 or running MinIO as part of a local development pipeline, it fits into modern containerized environments.
