What problem does it solve?

This Skill addresses the critical need to secure Linux server environments by implementing robust security configurations and hardening measures, reducing vulnerability to attacks.

Core Features & Use Cases

• SSH Hardening: Configures SSH for secure remote access, disabling root login and password authentication.
• User Security: Enforces strong password policies and audits sudo usage.
• Firewall Configuration: Sets up UFW or iptables to restrict network access.
• Kernel Hardening: Applies security-focused kernel parameters.
• File Permissions: Ensures critical system files have restrictive permissions.
• Audit Configuration: Sets up auditd for system event logging.
• Use Case: When deploying a new web server, use this skill to ensure it meets baseline security standards before going into production.
