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.

When looking at the broad landscape of IT automation tools, you’ll find dozens (if not hundreds) of tools that seem like viable solutions to your automation needs. Almost all of those tools can be broken down into two categories: Open source automation tools and commercial automation tools. (Open source automation tools with a commercial offering are still considered open source, even if the commercial edition has a price tag.)

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.
