PCI DSS compliance is often seen as a one-off task, that is, you do the audit, implement controls, and then move on. But then there comes the problem - systems aren’t static, meaning that files, scripts, and configurations change constantly, and even small untracked changes can create gaps that lead to non-compliance or security issues. This is where File Integrity Monitoring (FIM) comes in. It tracks critical files, system binaries, scripts, and configs in real time, alerting when anything changes unexpectedly. For PCI DSS, this is exactly what’s required, from preventing unauthorized changes...

Remote work is no longer a contingency – it’s the operating norm. Yet the security posture for that work often leans on virtual desktops as a default, even when the workforce is dominated by bring‑your‑own‑device (BYOD) users and short‑term contractors. Virtual desktop infrastructure (VDI) can centralize risk, but it can also centralize failure, expand the admin plane, and add latency that users will work around. This piece examines when VDI stops being the safest choice and what to use instead. I’ll compare concrete control patterns, such as secure local enclaves, strong identity guardrails...
