+# Security Solutions
+
+This section documents my solutions to security-related scenarios, including SELinux, firewall configuration, and security hardening.
+
+## Scenario: SELinux Configuration
+
+### Original Problem
+[To be filled with actual scenario]
+
+### Environment
+- OS Version: RHEL/Rocky Linux
+- Initial State: [Initial security configuration]
+- Required Outcome: [Desired security setup]
+
+### Solution Steps
+1. Check Current SELinux Status
+   ```bash
+   # Check SELinux status
+   getenforce
+   
+   # Check SELinux contexts
+   ls -Z /var/www/html
+   ```
+   [Explanation of current state]
+
+2. Configure SELinux Policies
+   ```bash
+   # Set SELinux boolean
+   setsebool -P httpd_can_network_connect on
+   
+   # Modify context
+   semanage fcontext -a -t httpd_sys_content_t "/custom/path(/.*)?"
+   ```
+   [Explanation of configuration]
+
+3. Apply Changes
+   ```bash
+   # Restore contexts
+   restorecon -Rv /custom/path
+   ```
+   [Explanation of changes]
+
+### Verification
+```bash
+# Verify SELinux status
+sestatus
+
+# Check audit logs
+ausearch -m AVC -ts recent
+
+# Test functionality
+curl localhost/custom/path
+```
+
