Discover WhimSE (What Have I Modified in SELinux), a new tool designed to simplify SELinux policy management in this 14-minute conference talk from DevConf.CZ 2025. Learn how this innovative utility addresses the common challenge of tracking modifications in complex SELinux environments where multiple modules, rules, and packages make it difficult to monitor policy changes. Explore how WhimSE scans your current policy and compares it against clean policies from installed packages to identify all modifications, including changed, removed, or added policy modules, alterations made through userspace tools like semanage and setsebool, and manual configuration file changes. Understand the tool's capabilities for handling Distributed SELinux Policy and see how it can help system administrators troubleshoot policy issues, whether they made the changes themselves or inherited a modified system from others.
