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 single runc bug (CVE-2024-21626) enabled full container escapes in early 2024 — proof that provenance and network defaults matter as much as image scanning.
The Morris Worm hit ~6,000 machines in 1988 via one unsafe gets() call. We build and hijack a stack overflow in C++ to teach why canaries and ASLR exist.
Microsoft has said for years that ~70% of the CVEs it patches trace to memory-safety bugs — here's how modern C++ actually closes that gap.
A CVSS 9.8 flaw in Apache Commons Configuration 2.4–2.7 let default interpolators run script-engine expressions from untrusted config strings.
Drupal 7's 2025 end-of-life left unsupported sites exposed; here's a concrete checklist for module vetting, access control, and patch cadence on Drupal 10/11.
Terraform's own drift check can return an ambiguous exit code — here's how declared IaC state quietly diverges from live cloud resources, and how to catch it.
Falco graduated CNCF in February 2024, Tetragon enforces in-kernel, and Tracee ships 330+ prebuilt eBPF detections — here's when each one actually wins.
Linters flag every eval() call; SAST tools flag the two an attacker can reach. Here's how taint tracking works, and what it costs in precision and compute.
