A utility helping developers to explorer SELinux policies

SELinux Explorer

SELinux Explorer is a utility designed to help developers explore and visualize SELinux policies, with a focus on Android SELinux at present. The project initially started as a command-line tool but has since evolved to include a graphical user interface (GUI) for better usability and to provide additional features such as filtering, generating custom output, and reusing data.

The tool supports the following file types:

• file_contexts
• service_contexts
• vndservice_contexts
• hwservice_contexts
• property_contexts
• seapp_contexts
• *.te

Please note: The tool is a work in progress and might have some issues or require performance improvements. We welcome any bug reports, suggestions, or contributions.

Use cases

• Threat assessment and cybersecurity analysis
  • Identify potential vulnerabilities in policies
  • Detect possible privilege escalation paths
• Android app development
  • Debug and optimize SELinux policies for custom apps
  • Verify proper policy configuration
• System administration
  • Audit and review SELinux policies
  • Improve system security and compliance
• Security research
  • Analyze and understand complex policy structures
  • Develop new security solutions and enhancements
• Documentation
