General Purpose Operating System Security Requirements Guide

Rules, Groups, and Values defined within the XCCDF Benchmark

  • The operating system must protect audit information from unauthorized 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...

  • SRG-OS-000063

    Group
  • The operating system must allow only the ISSM (or individuals or roles appointed by the ISSM) to select which auditable events are to be audited.

    Without the capability to restrict which roles and individuals can select which events are audited, unauthorized personnel may be able to prevent the auditing of critical events. Misconfigured audi...

  • SRG-OS-000064

    Group
  • The operating system must generate audit records when successful/unsuccessful attempts to access privileges occur.

    Without generating audit records that are specific to the security and mission needs of the organization, it would be difficult to establish, correlate, and investigate the events relating to an in...
    Rule Medium Severity
  • SRG-OS-000066

    Group
  • The operating system, for PKI-based authentication, must validate certificates by constructing a certification path (which includes status information) to an accepted trust anchor.

    Without path validation, an informed trust decision by the relying party cannot be made when presented with any certificate not already explicitly trusted. A trust anchor is an authoritative entit...

  • SRG-OS-000067

    Group
  • SRG-OS-000068

    Group
  • The operating system must map the authenticated identity to the user or group account for PKI-based authentication.

    Without mapping the certificate used to authenticate to the user account, the ability to determine the identity of the individual user or group will not be available for forensic analysis.

  • SRG-OS-000069

    Group
  • The operating system must enforce password complexity by requiring that at least one uppercase character be used.

    Use of a complex password helps to increase the time and resources required to compromise the password. Password complexity, or strength, is a measure of the effectiveness of a password in resistin...

    Group
  • SRG-OS-000071

  • The operating system must enforce password complexity by requiring that at least one numeric character be used.

    Use of a complex password helps to increase the time and resources required to compromise the password. Password complexity, or strength, is a measure of the effectiveness of a password in resistin...

  • SRG-OS-000073

    Group
  • The operating system must store only encrypted representations of passwords.

    Passwords need to be protected at all times, and encryption is the standard method for protecting passwords. If passwords are not encrypted, they can be plainly read (i.e., clear text) and easily c...

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.
