SRG-NET-000395
Group -
The Enterprise Voice, Video, and Messaging Session Manager, when using locally stored user accounts, must automatically lock the account until the locked account is released by an administrator when three unsuccessful logon attempts in 15 minutes are exceeded.
By limiting the number of failed login attempts, the risk of unauthorized system access via user password guessing, otherwise known as brute forcing, is reduced. Limits are imposed by locking the a...Rule Medium Severity -
SRG-NET-000400
Group -
For accounts using password authentication, the Enterprise Voice, Video, and Messaging Session Manager must be configured to 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 Medium Severity -
SRG-NET-000506
Group -
The Enterprise Voice, Video, and Messaging Session Manager must generate session (call) records when concurrent logons from multiple endpoints occur.
Without generating audit (session) records that are specific to the security and mission needs of the organization, it would be difficult to establish, correlate, and investigate the events relatin...Rule Medium Severity -
SRG-NET-000509
Group -
When using locally stored user accounts, the Enterprise Voice, Video, and Messaging Session Manager must generate audit records for all account creations, modifications, disabling, and termination events.
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 -

SRG-NET-000512
Group -
The Enterprise Voice, Video, and Messaging Session Manager must be configured in accordance with the security configuration settings based on DOD security configuration or implementation guidance, including STIGs, NSA configuration guides, CTOs, and DTMs.
Configuring the network element to implement organization-wide security implementation guides and security checklists ensures compliance with federal standards and establishes a common security bas...Rule Medium Severity -

SRG-NET-000520
Group -
When using PKI, the Enterprise Voice, Video, and Messaging Session Manager must validate certificates used for Transport Layer Security (TLS) functions by performing RFC 5280-compliant certification path validation.
A certificate's certification path is the path from the end entity certificate to a trusted root certification authority (CA). Certification path validation is necessary for a relying party to make...Rule Medium Severity -
SRG-NET-000520
Group -
The Enterprise Voice, Video, and Messaging Session Manager must be configured to use a voice or video VLAN, separate from all other VLANs.
When network elements do not dynamically reconfigure the data security attributes as data is created and combined, the possibility exist that security attributes will not correctly reflect the data...Rule Medium Severity -
SRG-NET-000522
Group -
When using locally stored user accounts, the Enterprise Voice, Video, and Messaging Session Manager must store only cryptographic representations of passwords.
If passwords and PSKs are not encrypted when stored, they may be read if the storage location is compromised. Note that DOD requires the use two-factor, CAC-enabled authentication and the use of ...Rule Medium Severity -
SRG-NET-000530
Group -
The Enterprise Voice, Video, and Messaging Session Manager must be configured to use only TLS 1.2 or greater for all TLS and SSL communications.
Using older unauthorized versions or incorrectly configuring protocol negotiation makes the gateway vulnerable to known and unknown attacks that exploit vulnerabilities in this protocol. This requ...Rule High 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.
