SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Host security hardening and risk-tolerance configuration for UAGENT deployments. Use when a user asks for security audits, firewall/SSH/update hardening, risk posture, exposure review, UAGENT cron scheduling for periodic checks, or version status checks on a machine running UAGENT (laptop, workstation, Pi, VPS).

Core Features & Use Cases

  • Read-only discovery and context establishment: infer OS, privilege level, deployment context, backups status, and exposure surface without altering the host.
  • Reversible hardening guidance: provide structured steps to reduce attack surface while preserving access to UAGENT.
  • Audit readiness and governance: generate remediation plans with clear rollbacks and documentation for security reviews, including scheduling.

Quick Start

Run healthcheck to assess your host and apply risk-aware hardening steps for UAGENT deployments.

Frequently Asked Questions about healthcheck

FAQPage Schema
How do I perform a security audit and harden SSH on a host running an autonomous agent?

Run a security audit to identify gaps on your UAGENT host, which then guides OS hardening by providing reversible steps for SSH, firewall, and update configurations to reduce exposure while preserving agent access.

Can I automate periodic compliance checks and risk assessments for my deployment?

Yes, you can schedule periodic audits and compliance checks for your UAGENT deployment, automating risk-management tasks and generating governance documentation to maintain audit readiness over time.

Does the host hardening process require manual rollback steps if access is lost?

No, the hardening process generates a formal remediation plan that includes explicit rollbacks and requires confirmations before applying changes, ensuring you can safely reverse configurations without losing access.

What is read-only context collection during a server security review?

Read-only context collection infers the OS, privilege level, deployment context, backups status, and exposure surface of your host without altering the system, establishing a safe baseline for security analysis.

Can I use this hardening approach on edge gateways and workstations or is it only for servers?

You can use this hardening approach on local workstations, servers, and edge gateways alike, as it adapts risk-management and audit readiness tasks to any machine running a UAGENT deployment.

What's the best way to ensure model self-checks before executing hardening tasks?

The process enforces model self-checks before executing any host modifications, ensuring the autonomous agent verifies its own operational state and context prior to applying remediation plans.
