# 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
```
