The Cisco ISE must generate audit records containing the full-text recording of privileged commands.
<VulnDiscussion>Reconstruction of harmful events or forensic analysis is not possible if audit records do not contain enough information. O...Rule Medium Severity -
The Cisco ISE must be configured with only one local web-based account to be used as the account of last resort in the event the authentication server is unavailable.
<VulnDiscussion>Authentication for administrative (privileged level) access to the device is required at all times. An account can be created...Rule Medium Severity -

The Cisco ISE must be configured to enforce the limit of three consecutive invalid logon attempts, after which time it must lock out the user account from accessing the device for 15 minutes.

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.
