SRG-NET-000138-VPN-000490
Group -
The Cisco ASA remote access VPN server must be configured to identify and authenticate users before granting access to the network.
To assure accountability and prevent unauthenticated access, organizational users must be identified and authenticated to prevent potential misuse and compromise of the system. Organizational user...Rule Medium Severity -
SRG-NET-000140-VPN-000500
Group -
The Cisco ASA remote access VPN server must be configured to enforce certificate-based authentication before granting access to the network.
To assure accountability and prevent unauthenticated access, non-privileged users must utilize multifactor authentication to prevent potential misuse and compromise of the system. Multifactor auth...Rule High Severity -
SRG-NET-000166-VPN-000590
Group -
The Cisco ASA remote access VPN server must be configured to map the distinguished name (DN) from the client’s certificate to entries in the authentication server to determine authorization to access the network.
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. This re...Rule Medium Severity -
SRG-NET-000041-VPN-000110
Group -
The Cisco ASA remote access VPN server must be configured to display the Standard Mandatory DoD Notice and Consent Banner before granting access to the network.
Display of a standardized and approved use notification before granting access to the network ensures privacy and security notification verbiage used is consistent with applicable federal laws, Exe...Rule Medium Severity -
SRG-NET-000079-VPN-000300
Group -
The Cisco ASA remote access VPN server must be configured to generate log records containing information that establishes the identity of any individual or process associated with the event.
Without information that establishes the identity of the subjects (i.e., users or processes acting on behalf of users) associated with the events, security personnel cannot determine responsibility...Rule Medium Severity -
SRG-NET-000088-VPN-000310
Group -
The Cisco ASA remote access VPN server must be configured to generate log records containing information to establish where the events occurred.
Without establishing where events occurred, it is impossible to establish, correlate, and investigate the events leading up to an outage or attack. In order to compile an accurate risk assessment,...Rule Medium Severity -
SRG-NET-000089-VPN-000330
Group -
The Cisco ASA remote access VPN server must be configured to generate log records containing information to establish the source of the events.
Without establishing the source of the event, it is impossible to establish, correlate, and investigate the events leading up to an outage or attack. In order to compile an accurate risk assessment...Rule Low Severity -
SRG-NET-000091-VPN-000350
Group -
The Cisco ASA remote access VPN server must be configured to produce log records containing information to establish the outcome of the events.
Without information about the outcome of events, security personnel cannot make an accurate assessment as to whether an attack was successful or if changes were made to the security state of the ne...Rule Medium Severity -
SRG-NET-000062-VPN-000200
Group -
The Cisco ASA remote access VPN server must be configured to use TLS 1.2 or higher to protect the confidentiality of remote access connections.
Using older unauthorized versions or incorrectly configuring protocol negotiation makes the gateway vulnerable to known and unknown attacks that exploit vulnerabilities in this protocol. NIST SP 8...Rule High Severity -
SRG-NET-000063-VPN-000210
Group -
The Cisco ASA remote access VPN server must be configured to use a FIPS-validated algorithm and hash function to protect the integrity of TLS remote access sessions.
Without integrity protection, unauthorized changes may be made to the log files and reliable forensic analysis and discovery of the source of malicious system activity may be degraded. Remote acce...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.
