Container-handling security fundamentals: immutability, signing, and privilege drops
Two runc CVEs, five years apart, both turned root-in-container into root-on-host — proof that container isolation needs backup, not blind trust.
Deep dives, practical guides, and incident analyses from engineers who build Safeguard. No fluff, no vendor FUD — just what you need to ship secure software.
Two runc CVEs, five years apart, both turned root-in-container into root-on-host — proof that container isolation needs backup, not blind trust.
A typical java:17 image ships a full OS and root shell; distroless plus JVM container-awareness flags cut that attack surface to almost nothing.
BuildKit's --secret flag shipped in Docker 18.09 in 2018, yet ENV and --build-arg leaks into image layers remain the most common way containers ship credentials.
Standard Docker Hub images ship 50-60 known CVEs on average. Here's the checklist that gets containers from base image to runtime without carrying them along.
Multi-stage builds are pitched as a way to shrink images. Their bigger payoff is security: build secrets, compilers, and toolchains that never reach production. Here is how to use them right.
A service mesh can give you mutual TLS between every service, identity-based authorization, and encrypted traffic without touching application code — or it can become an over-privileged proxy layer you never locked down. Here is how to do it right.
eBPF lets you observe and enforce security at the kernel level — every syscall, network connection, and process exec — without kernel modules or instrumenting your apps. Here is how tools like Falco, Tetragon, and Cilium use it to catch what image scanning cannot.
Layer caching makes builds fast — and quietly bakes secrets into layers, hides unpatched base images, and poisons shared CI caches. Here is how to keep caching without the exposure.
Scanning tells you what could go wrong before deploy. Runtime monitoring tells you what is going wrong right now. Here is how to detect container attacks as they happen.
