Lesson 1advanced

Secure C Coding: CWE, CERT & Undefined Behaviour

Eliminate classes of vulnerabilities: buffer overflows, integer wrap, use-after-free, format strings, and TOCTOU races.

Lesson 2advanced

Sandboxing with seccomp-bpf & Landlock

Design a syscall policy, build a seccomp filter with libseccomp, and use Landlock for filesystem sandboxing on modern kernels.

Lesson 3advanced

Capabilities, SELinux & AppArmor

Drop root privileges with capability bounding sets, write SELinux policy modules, and confine applications with AppArmor profiles.

Supply Chain Integrity: SBOM, Reproducible Builds & Signing

Generate SBOMs with CycloneDX, achieve bit-for-bit reproducible builds, sign artifacts with cosign/sigstore, and verify in CI/CD.
