On-Premises API Security on Kubernetes: What It Actually Looks Like in Practice

Let’s Talk About Where Your APIs Actually Run Quick answer: On-premises API security keeps API discovery, detection, and enforcement inside your own perimeter instead of a third-party cloud—the model regulated industries need. Deploying it natively on Kubernetes sidecar sensors → a discovery...

kernel: selinux: fix overlayfs mmap() and mprotect() access checks

A flaw was found in the Linux kernel's SELinux security module when handling overlayfs. The existing security model for overlayfs does not properly enforce access controls for mmap and mprotect operations. This oversight could allow a local attacker to bypass intended security policies, potential...
