    Rule Medium Severity
  • SRG-OS-000105-GPOS-00052

    Group
  • The Oracle Linux operating system must have the required packages for multifactor authentication installed.

    Rule Medium Severity
  • SRG-OS-000057-GPOS-00027

    Group
  • The Oracle Linux operating system must protect audit information from unauthorized read, modification, or deletion.

    If audit information were to become compromised, then forensic analysis and discovery of the true source of potentially malicious system activity is impossible to achieve. To ensure the veracity o...
    Rule Medium Severity
  • SRG-OS-000480-GPOS-00227

    Group
  • The Oracle Linux operating system must be configured so the x86 Ctrl-Alt-Delete key sequence is disabled in the Graphical User Interface.

    A locally logged-on user who presses Ctrl-Alt-Delete, when at the console, can reboot the system. If accidentally pressed, as could happen in the case of a mixed OS environment, this can create the...

  • SRG-OS-000480-GPOS-00227

    Group
  • The Oracle Linux operating system must be configured so that all world-writable directories are owned by root, sys, bin, or an application user.

    If a world-writable directory is not owned by root, sys, bin, or an application User Identifier (UID), unauthorized users may be able to modify files created by others. The only authorized public ...

  • SRG-OS-000114-GPOS-00059

    Group
  • The Oracle Linux operating system must disable the graphical user interface automounter unless required.

    Automatically mounting file systems permits easy introduction of unknown devices, thereby facilitating malicious activity. Satisfies: SRG-OS-000114-GPOS-00059, SRG-OS-000378-GPOS-00163, SRG-OS-000...
    Rule Medium Severity
  • SRG-OS-000373-GPOS-00156

    Group
  • The Oracle Linux operating system must be configured so users must re-authenticate for privilege escalation.
