FAQPage Schema

How do I audit and harden the operating system running ErnOS?▼

To audit and harden an ErnOS host, you need a security tool that performs deep system checks and applies configurations based on your risk tolerance. This Skill executes those security audits and generates remediation plans with exact commands.

What's the best way to configure a firewall and restrict SSH access on my ErnOS server?▼

Configuring a firewall and restricting SSH access on an ErnOS server requires a structured hardening plan. This Skill generates step-by-step remediation commands for firewall and SSH hardening, aligning settings with your chosen security profile.

Can I apply different security profiles based on my risk tolerance for system hardening?▼

System hardening can be aligned with your risk tolerance by selecting predefined security profiles. This Skill guides you through choosing and implementing profiles like Home/Workstation Balanced or VPS Hardened to match your specific environment.

How does a security audit handle state-changing actions like system updates?▼

A security audit handles state-changing actions by requiring explicit user approval before execution. This Skill prioritizes reversible changes and provides executable commands for update hardening, ensuring you maintain control over system modifications.

Does this hardening process check the current ErnOS version status during a security audit?▼

Checking the ErnOS version status is a core part of the security audit process. This Skill verifies your current version status alongside deep operating system checks to ensure your host configuration is secure and up to date.
