Cisco IOS Switch NDM Security Technical Implementation Guide

Rules, Groups, and Values defined within the XCCDF Benchmark

  • The Cisco switch must be configured to enforce password complexity by requiring that at least one uppercase character be used.

    Use of a complex passwords 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 resisti...
    Rule Medium Severity
  • The Cisco switch must be configured to enforce password complexity by requiring that at least one lowercase 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...
    Rule Medium Severity
  • The Cisco switch must be configured to 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...
    Rule Medium Severity
  • The Cisco switch must be configured to enforce password complexity by requiring that at least one special 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...
    Rule Medium Severity
  • The Cisco switch must be configured to require that when a password is changed, the characters are changed in at least eight of the positions within the password.

    If the application allows the user to consecutively reuse extensive portions of passwords, this increases the chances of password compromise by increasing the window of opportunity for attempts at ...
    Rule Medium Severity
  • The Cisco switch must only store cryptographic 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...
    Rule High Severity
  • The Cisco switch must be configured to terminate all network connections associated with device management after five minutes of inactivity.

    Terminating an idle session within a short time period reduces the window of opportunity for unauthorized personnel to take control of a management session enabled on the console or console port th...
    Rule High Severity
  • The Cisco switch must be configured to automatically audit account enabling actions.

    Once an attacker establishes initial access to a system, the attacker often attempts to create a persistent method of reestablishing access. One way to accomplish this is for the attacker to enable...
    Rule Medium Severity
  • The Cisco switch must be configured to allocate audit record storage capacity in accordance with organization-defined audit record storage requirements.

    To ensure that network devices have a sufficient storage capacity in which to write the audit logs, they need to be able to allocate audit record storage capacity. The task of allocating audit reco...
    Rule Medium Severity
  • The Cisco switch must be configured to synchronize its clock with the primary and secondary time sources using redundant authoritative time sources.

    The loss of connectivity to a particular authoritative time source will result in the loss of time synchronization (free-run mode) and increasingly inaccurate time stamps on audit events and other ...

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.
