kernel: crypto api unprivileged arbitrary module load via request_module()

A flaw was found in the way the Linux kernel's Crypto subsystem handled automatic loading of kernel modules. A local user could use this flaw to load any installed kernel module, and thus increase the attack surface of the running kernel...

Windows Sandbox Attack Surface Analysis

Posted by James Forshaw, Quartermaster of Tools Analysing the attack surface of user-mode sandboxed applications is a good way to hunt for elevation of privilege vulnerabilities. Much of the task of enumerating the attack surface could be done manually, but that’s a very tedious and error prone...

System Hardening Guide

The purpose of system hardening is to eliminate as many security risks as possible. Hardening is the process of securing a system by reducing its attack surface. A system has a larger vulnerability surface the more functions it fulfills; in principle a single-function system is more secure than a...
