Demystifying the complexities of system security. We provide deep technical analysis, practical engineering guides, and threat research for the modern stack.
In an era where digital infrastructure underpins critical services, understanding the layers beneath the application code is not optional—it is a necessity. Udero exists to bridge the gap between high-level security policies and low-level system implementation.
We move beyond the buzzwords to explore the mechanics of vulnerabilities and the engineering behind defense. Whether it is dissecting a Linux kernel exploit, implementing post-quantum cryptography, or tracing malicious syscalls with eBPF, our goal is to empower engineers with actionable, deep technical knowledge.
The Linux kernel is the foundation of the cloud. Securing it requires more than just applying updates. We delve into Linux Security Modules (LSMs) like SELinux and AppArmor to enforce mandatory access control. We explore namespace isolation and cgroup resource limiting to understand container security at the root. From securing the boot chain with UEFI Secure Boot to runtime kernel protection, our research ensures your foundation is solid.
Cryptography is the mathematics of trust. We advocate for modern, misuse-resistant primitives like ChaCha20-Poly1305 and Curve25519. Our research extends to the frontier of cryptographic engineering, including Zero-Knowledge Proofs (ZKPs) for privacy-preserving computation and the urgent transition to Post-Quantum Cryptography (PQC) to protect data against future quantum threats.
As workloads move to Kubernetes and microservices, traditional perimeter defenses fail. Extended Berkeley Packet Filter (eBPF) represents a paradigm shift, allowing for programmable, sandboxed execution within the kernel. We explore how eBPF powers next-generation observability and security enforcement tools like Cilium and Tetragon, providing visibility into ephemeral cloud workloads that was previously impossible.
Security is an engineering discipline. It requires rigorous testing, formal verification, and a defensive mindset. Udero is committed to open-source security. We analyze supply chain risks, advocate for Software Bill of Materials (SBOMs), and support initiatives like Sigstore to ensure software integrity from commit to deployment.
