SUSE Linux Enterprise Micro (SLEM) 5 Security Technical Implementation Guide

Rules, Groups, and Values defined within the XCCDF Benchmark

  • SLEM 5 must employ FIPS 140-2/140-3 approved cryptographic hashing algorithm for system authentication (login.defs).

    <VulnDiscussion>Unapproved mechanisms that are used for authentication to the cryptographic module are not verified and therefore cannot be r...

The content of the drawer really is up to you. It could have form fields, definition lists, text lists, labels, charts, progress bars, etc. Spacing recommendation is 24px margins. You can put tabs in here, and can also make the drawer scrollable.
