As AI moves from the lab into the core of critical systems, security has become inseparable from the technology itself. A practical look at the threats facing AI in 2026—adversarial attacks, data poisoning, prompt injection—and how to defend against them.

Every modern application relies on secrets. Database passwords, API keys, SSH keys, TLS certificates, cloud credentials, Kubernetes tokens—these sensitive pieces of information enable applications and engineers to access critical systems. Yet despite their importance, secrets are often managed poorly. They end up scattered across source code repositories, CI/CD pipelines, engineers' laptops, configuration files, and internal documentation pages. This phenomenon is known as Secret Sprawl, and it is one of the most common security risks in modern software development. This is exactly the problem that HashiCorp Vault was designed to solve.
A low-cost smart car security system that uses face recognition (PCA/eigenfaces) on an Android board, combined with GSM and GPS, to detect unauthorized drivers, alert the owner, locate the vehicle, and remotely stop the engine.
