A NEMO host security audit performs deep checks on your operating system, network configuration, and NEMO's security settings. It evaluates your current posture against common vulnerabilities and generates an actionable remediation plan to close identified gaps.

Hardening SSH and firewalls for a NEMO deployment involves configuring deny-by-default network rules and restricting access to key-based authentication. The process aligns configurations with your defined risk tolerance to ensure host protection while preserving necessary access.

Aligning NEMO's security posture with a risk tolerance level like VPS Hardened is supported by configuring firewalls, access controls, and update policies. This guides the host machine's security settings to match your desired level of protection against vulnerabilities.

Generating a remediation plan for vulnerabilities found during a host security check produces a clear, step-by-step list of commands to fix the issues. This plan prioritizes reversibility and access preservation to safely resolve security gaps on your NEMO host.

Security hardening for NEMO deployments works across various operating systems by performing OS-level checks and integrating NEMO's security tooling. This ensures host security audits, firewall configurations, and update policies are applicable to your specific environment.

Running a security hardening audit before deploying NEMO to a new server ensures the environment is protected against common vulnerabilities. It checks the operating system and network configuration, allowing you to apply a deny-by-default firewall and restrict SSH access beforehand.
