SRG-APP-000400-NDM-000313
Group -
The Cisco ISE must prohibit the use of cached authenticators after an organization-defined time period.
Some authentication implementations can be configured to use cached authenticators. If cached authentication information is out-of-date, the validity of the authentication information may be quest...Rule Medium Severity -
SRG-APP-000179-NDM-000265
Group -
The Cisco ISE must use FIPS-validated SHA-2 (or greater) to protect the integrity of hash message authentication code (HMAC), Key Derivation Functions (KDFs), Random Bit Generation, and hash-only applications.
Without cryptographic integrity protections, information can be altered by unauthorized users without detection. Nonlocal maintenance and diagnostic activities are activities conducted by individu...Rule High Severity -
SRG-APP-000411-NDM-000330
Group -
The Cisco ISE must use FIPS-validated Keyed-Hash Message Authentication Code (HMAC) to protect the integrity of nonlocal maintenance and diagnostic communications.
Unapproved mechanisms that are used for authentication to the cryptographic module are not verified and therefore cannot be relied upon to provide confidentiality or integrity, and DoD data may be ...Rule Medium Severity -
SRG-APP-000411-NDM-000330
Group -
The Cisco ISE must verify the checksum value of any software download, including install files (ISO or OVA), patch files, and upgrade bundles.
Without cryptographic integrity protections, information can be altered by unauthorized users without detection. Nonlocal maintenance and diagnostic activities are those activities conducted by in...Rule High Severity -
SRG-APP-000412-NDM-000331
Group -
The Cisco ISE must be configured to implement cryptographic mechanisms using a FIPS 140-2 validated algorithm to protect the confidentiality of remote maintenance sessions.
This requires the use of secure protocols instead of their unsecured counterparts, such as SSH instead of telnet, SCP instead of FTP, and HTTPS instead of HTTP. If unsecured protocols (lacking cryp...Rule High Severity -
SRG-APP-000190-NDM-000267
Group -
The Cisco ISE must terminate all network connections associated with a device management session at the end of the session, or the session must be terminated after five minutes of inactivity except to fulfill documented and validated mission requirements.
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 -
SRG-APP-000224-NDM-000270
Group -
The Cisco ISE must generate unique session identifiers using a FIPS 140-2 approved Random Number Generator (RNG) using DRGB.
Sequentially generated session IDs can be easily guessed by an attacker. Employing the concept of randomness in the generation of unique session identifiers helps to protect against brute-force att...Rule Medium Severity -
SRG-APP-000231-NDM-000271
Group -
The Cisco ISE must only allow authorized administrators to view or change the device configuration, system files, and other files stored.
This requirement is intended to address the confidentiality and integrity of system information at rest (e.g., network device rule sets) when it is located on a storage device within the network de...Rule High Severity -
SRG-APP-000435-NDM-000315
Group -
The Cisco ISE must configure the control plane to protect against or limit the effects of common types of Denial of Service (DoS) attacks on the device itself by configuring applicable system options and internet-options.
DoS is a condition when a resource is not available for legitimate users. When this occurs, the organization either cannot accomplish its mission or must operate at degraded capacity. This require...Rule Medium Severity -
SRG-APP-000516-NDM-000350
Group -
The Cisco ISE must be configured to send log data to at least two central log servers for the purpose of forwarding alerts to the administrators and the information system security officer (ISSO).
The aggregation of log data kept on a syslog server can be used to detect attacks and trigger an alert to the appropriate security personnel. The stored log data can used to detect weaknesses in se...Rule Medium Severity

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.
