Automated Testing The IRS Office of Safeguards utilizes Tenable's industry standard compliance and vulnerability assessment tool, Nessus, to evaluate the security of systems (e.g., Windows, *NIX, Cisco) that store, process, transmit or receive federal tax information. We use Nessus to conduct configuration compliance checks using Center for Internet Security (CIS) benchmarks supplemented with some IRS-specific requirements. This process has been developed to provide agencies with enhanced information regarding the security controls in place to protect FTI. NESSUS Audit Files — 2022
