Below is the list of blog posts with the “linux security” tag.

From years of supporting NXLog Agent deployments across many environments, we’ve learned that while Linux generates a wealth of security logging, much of it remains underutilized. Critical security events are buried across multiple log files and subsystems, making it more complicated than it should be to spot suspicious activity. Efficient Linux security logging requires knowledge of which events matter and where to get them. Authentication attempts, privilege changes, package installations, audit events, and system shutdown events can all tell a story when viewed together.

Timely visibility into system activity is what separates effective defense from reactive analysis. Every operating system, application, and device logs a trail of evidence. However, transforming that trail into actionable intelligence requires the right tools. In our previous posts, we’ve walked you through: Visualizing VPN connection logs, Monitoring Windows security events, and Analyzing web server activity logs. In this final installment in our series on log visualization, we’re turning our attention to Linux security monitoring.
