    <GroupDescription></GroupDescription>
    Group
  • The SUSE operating system must employ FIPS 140-2 approved cryptographic hashing algorithm for system authentication (login.defs).

    &lt;VulnDiscussion&gt;Unapproved mechanisms that are used for authentication to the cryptographic module are not verified and therefore cannot be r...

    <GroupDescription></GroupDescription>
    Group
  • The SUSE operating system SSH daemon must be configured to only use Message Authentication Codes (MACs) employing FIPS 140-2 approved cryptographic hash algorithms.

    &lt;VulnDiscussion&gt;Without cryptographic integrity protections, information can be altered by unauthorized users without detection. Remote acce...

  • SRG-OS-000126-GPOS-00066

    <GroupDescription></GroupDescription>
    Group
  • The SUSE operating system SSH daemon must be configured with a timeout interval.

    &lt;VulnDiscussion&gt;Terminating an idle session within a short time period reduces the window of opportunity for unauthorized personnel to take c...

    <GroupDescription></GroupDescription>
    Group
  • The sticky bit must be set on all SUSE operating system world-writable directories.

    Group
  • The SUSE operating system must be configured to use TCP syncookies.

    <GroupDescription></GroupDescription>
    Group
  • The SUSE operating system for all network connections associated with SSH traffic must immediately terminate at the end of the session or after 10 minutes of inactivity.

    &lt;VulnDiscussion&gt;Automatic session termination addresses the termination of user-initiated logical sessions in contrast to the termination of ...

    <GroupDescription></GroupDescription>
    Group
  • All SUSE operating system persistent disk partitions must implement cryptographic mechanisms to prevent unauthorized disclosure or modification of all information that requires at-rest protection.

    &lt;VulnDiscussion&gt;SUSE operating systems handling data requiring data-at-rest protections must employ cryptographic mechanisms to prevent unaut...
    Rule High Severity
  • SRG-OS-000205-GPOS-00083

    <GroupDescription></GroupDescription>
    Group
  • The SUSE operating system must generate error messages that provide information necessary for corrective actions without revealing information that could be exploited by adversaries.

    &lt;VulnDiscussion&gt;Any operating system providing too much information in error messages risks compromising the data and security of the structu...
