Good security metrics create clarity and drive action. Bad metrics create noise, blame, and workarounds. The goal is to measure outcomes that engineering teams can influence, then use those signals...

Auditd provides reliable, tamper-resistant logging for sensitive system activity. A focused ruleset can highlight privilege escalation attempts without flooding your logs. This post covers a minim...

Secrets in repos are a reliability problem and a security risk. A simple secrets manager plus a minimal CI integration eliminates most of the pain without adding heavy process. This post shows a s...

Email spoofing is still one of the easiest ways to bypass defenses. SPF, DKIM, and DMARC are the baseline controls that let receivers verify who is allowed to send mail on behalf of your domain. Th...

A scanner run is not a vulnerability management program. The difference is cadence, prioritization, and verification. Even in a home lab, a light but consistent workflow keeps systems patched, redu...

Software supply chain attacks target the build pipeline, not just the code. Defending against them requires visibility into dependencies, trusted build provenance, and artifact signing. SBOMs, SLSA...

When logs are noisy, clustering is more useful than reading line by line. A small clustering pipeline can group similar messages, let you triage the rare clusters, and then use a local LLM to summa...

Ransomware response is mostly about recovery. If your backups are slow, mutable, or untested, you do not have a recovery plan. A home lab is the perfect place to practice immutable backups, snapsho...

A reverse proxy WAF is a practical defense layer for web apps in a lab. Nginx gives you stability and performance, while ModSecurity provides a rule engine that can inspect HTTP requests for malici...

Binary hardening is one of the most reliable ways to reduce exploitability. Modern Linux toolchains can add protections like RELRO, PIE, NX, and CET with simple build flags. In a lab, you can compi...
