Announcing the release of Oracle Linux 7 Security Technical Implementation Guide (STIG) OpenSCAP profile

Avi Miller
Senior Manager

On February 28 2020, the Defence Information Systems Agency (DISA) released the Oracle Linux 7 Security Technical Implementation Guide (STIG) Release 1 Version 1 (R1V1). Oracle has implemented the published STIG in Security Content Automation Protocol (SCAP) format and included it in the latest release of the scap-security-guide package for Oracle Linux 7. This can be used in conjunction with the OpenSCAP tool shipped with Oracle Linux to validate a server against the published implementation guide. The validation process can also suggest and in some cases automatically apply remediation in cases where compliance is not met.

Running a STIG compliance scan with OpenSCAP

To validate a server against the published profile, you will need to install the OpenSCAP scanner tool and the SCAP Security Guide content:

# yum install openscap scap-security-guide
