What is the best way to secure SSH access on a remote server?

Securing SSH access on a remote server involves identifying insecure configurations and applying automated hardening fixes. This includes remediating common misconfigurations to prevent unauthorized access and bolstering overall server security.

Can I run a security audit on my server without applying fixes immediately?

Yes, you can run a standalone security audit on your server to check for outdated packages, insecure SSH configurations, and firewall status without applying fixes, allowing you to review vulnerabilities before executing automated hardening.

Does automated server hardening configure firewalls and intrusion prevention systems?

Automated server hardening does configure firewalls and enables intrusion prevention systems. It applies safe fixes to ensure your VPS is protected against common vulnerabilities and network threats immediately after deployment.

When do I need to run emergency hardening on my VPS?

Emergency hardening on a VPS is needed when you must instantly secure a server against active threats or critical misconfigurations. It provides immediate remediation for vulnerabilities related to SSH access, system updates, and firewalls.

Can I generate a security report after auditing my remote server?

Yes, you can generate a security report after auditing your remote server. The functionality supports report generation to document identified misconfigurations and the status of your system updates, SSH access, and firewalls.
