About
aartool audits a Linux host and shows which attack chains are complete end to end, instead of only listing separate findings. It produces an ordered plan of what to fix first and what each fix costs, applies changes only when the user types apply, then verifies that only the intended changes occurred. It includes 109 CIS checks, 52 Ansible roles, and SARIF and Prometheus output.
At a glance
aartool audits Linux hosts and turns findings into a prioritized hardening plan. It is worth evaluating when you already have audit results but need to see what a proposed fix would change before applying it.
Good fit
Linux operators who can test changes on a representative host and compare before-and-after findings.
Consider something else when
Use a separate compliance process if you need formal certification, or defer remediation if you cannot test connectivity and roll back changes.
Start here
Read the synthetic demo and inspect one finding, such as an SSH policy. Review the proposed change on a disposable host before considering a targeted apply.
Cost and requirements
GPL 3.0 or later. The project documents a standalone audit script and Ansible-based remediation for supported Linux distributions.
Limits to know
Applying hardening changes host configuration and can affect access. Check platform coverage and review each target and change. A clean audit cannot establish that every service remains healthy.
