EBPF Behavioral Detection Hero Esm H350
How to Learn Tips and TricksPrice Tag%201security framework process monitoring

Building effective behavioral detections starts with understanding how processes behave at runtime, rather than simply collecting more logs. eBPF gives Linux security teams the visibility needed to correlate those behaviors into meaningful detections, moving away from static signatures and toward real-time analysis. . The first surprise for most people coming from auditd or legacy log collectors is how much context suddenly becomes available. Instead of just seeing that a shell executed, you...

How to Learn Tips and TricksPrice Tag%201incident response linux

When a security alert fires, the panic often sets in before the analysis. Many administrators instinctively reach for /var/log/auth.log or journalctl , but those logs tell only a partial story. They document successful logins and authentication attempts, but they rarely capture the granular "how" of a post-compromise environment. To truly reconstruct an attack, you need to master audit logs . Unlike standard authentication logs, Linux audit logs (managed by auditd ) record system-level...

SELinux troubleshooting is a necessary skill for any system administrator. When a service fails despite correct file permissions and ownership, the immediate instinct is often to disable SELinux to confirm if the security policy is the bottleneck. While turning off enforcement frequently "fixes" the immediate symptom, it hides the underlying configuration flaw—such as an incorrect context or a policy violation—that could leave your system exposed. This guide outlines a systematic approach to...

How to Secure My NetworkPrice Tag%201incident response open-source

When a production server spikes at 99% CPU or the disk starts grinding, the knee-jerk reaction is usually to blame a bad code push or a runaway backup job. But if you’ve spent enough time in security incident response, you know that "performance issues" are often the first sign that you’re dealing with Linux malware. . If you don't have a systematic way to look past the performance graphs, you’re just guessing. Here is how you use Linux commands to peel back the layers when a system starts...

How to Secure My NetworkPrice Tag%201network security Linux administration

Open ports have a way of accumulating over time. A test environment gets deployed and never removed. An administrative interface is exposed for troubleshooting and left in place. A database that was supposed to listen internally ends up reachable from the internet. . Attackers look for these mistakes constantly. Redis, Elasticsearch, MongoDB, Jenkins, and similar services still show up on internet-facing systems where they were never meant to be exposed. Sometimes it's a temporary change that...
