Cisco ISE NDM Security Technical Implementation Guide
Rules, Groups, and Values defined within the XCCDF Benchmark
-
The Cisco ISE must generate audit records when successful logon attempts 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 -
The Cisco ISE must generate audit records for privileged activities or other system-level access.
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 -
The Cisco ISE must generate audit records when concurrent logons from different workstations 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 -
The Cisco ISE must limit audit record storage capacity for all locally stored logs.
In order to ensure 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 ...Rule Medium Severity -
The Cisco ISE must configure a remote syslog where audit records are stored on a centralized logging target that is different from the system being audited.
Information stored in one location is vulnerable to accidental or incidental deletion or alteration. Storing audit logs to a different system than that being audited is a common process in informa...Rule Medium Severity -
The Cisco ISE must send an alarm to one or more individuals when the monitoring collector process has an error or failure.
It is critical for the appropriate personnel to be aware if a system is at risk of failing to process audit logs as required. Without an alert, security personnel may be unaware of an impending fai...Rule Medium Severity -
The Cisco ISE must be configured to synchronize internal information system clocks 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 ...Rule Medium Severity -
The Cisco ISE must enforce access restrictions associated with changes to the firmware, OS, and hardware components.
Changes to the hardware or software components of the network device can have significant effects on the overall security of the network. Therefore, only qualified and authorized individuals should...Rule Medium Severity -
The Cisco ISE must be running an operating system release that is currently supported by the vendor.
Network devices running an unsupported operating system lack current security fixes required to mitigate the risks associated with recent vulnerabilities. The recommended best practice is for the ...Rule Medium Severity -
The Cisco ISE must generate log records for a locally developed list of auditable events.
Logging the actions of specific events provides a means to investigate an attack; to recognize resource utilization or capacity thresholds; or to identify an improperly configured network device. I...Rule Medium Severity -
For accounts using password authentication, the Cisco ISE must implement replay-resistant authentication mechanisms for network access to privileged accounts.
A replay attack may enable an unauthorized user to gain access to the application. Authentication sessions between the authenticator and the application validating the user credentials must not be ...Rule Medium Severity -
The Cisco ISE must be configured to authenticate SNMP messages using a FIPS-validated Keyed-Hash Message Authentication Code (HMAC).
Without authenticating devices, unidentified or unknown devices may be introduced, thereby facilitating malicious activity. Bidirectional authentication provides stronger safeguards to validate the...Rule Medium Severity -
The Cisco ISE must authenticate Network Time Protocol (NTP) sources using authentication that is cryptographically based.
If NTP is not authenticated, an attacker can introduce a rogue NTP server. This rogue server can then be used to send incorrect time information to network devices, which will make log timestamps i...Rule Medium Severity -
For accounts using password authentication, the Cisco ISE must enforce a minimum 15-character password length.
Password complexity, or strength, is a measure of the effectiveness of a password in resisting attempts at guessing and brute-force attacks. Password length is one factor of several that helps to d...Rule Medium Severity -
For accounts using password authentication, the Cisco ISE must 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 -
For accounts using password authentication, the Cisco ISE must 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 -
For accounts using password authentication, the Cisco ISE must enforce password complexity by requiring that at least one digit 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 -
For accounts using password authentication, the Cisco ISE must 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 -
For accounts using password authentication, the Cisco ISE must use FIPS-validated SHA-2 or later protocol to protect the integrity of the password authentication process.
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 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

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.
