SRG-NET-000354
Group -
The Enterprise Voice, Video, and Messaging Session Manager supporting Command and Control (C2) communications must associate multilevel precedence and preemption (MLPP) attributes when exchanged between unified capabilities (UC) system components.
If MLPP attributes are not associated with the information being transmitted between systems, then access control policies and information flows which depend on these MLPP attributes will not funct...Rule Medium Severity -
SRG-NET-000355
Group -
The Enterprise Voice, Video, and Messaging Session Manager must only allow the use of DOD-approved PKI certificate authorities when using PKI.

SRG-NET-000362
Group -
The Enterprise Voice, Video, and Messaging Session Manager must be configured to protect against or limit the effects of all types of denial-of-service (DoS) attacks by employing organizationally defined security safeguards.
A network element experiencing a DoS attack will not be able to handle the traffic load. The high CPU utilization caused by a DoS attack will also have impact control keep-alives and timers used fo...Rule Medium Severity -
SRG-NET-000363
Group -
The Enterprise Voice, Video, and Messaging Session Manager must be configured to limit and reserve bandwidth based on priority of the traffic type.
Without the implementation of safeguards which allocate network communication resources based on priority, network availability, and particularly high priority traffic, may be dropped or delayed. D...Rule Medium Severity -
SRG-NET-000371
Group -
The Enterprise Voice, Video, and Messaging Session Manager must be configured to protect the confidentiality and integrity of transmitted configuration files, signaling, and media streams.
Without protection of the transmitted information, confidentiality and integrity may be compromised as unprotected communications can be intercepted and either read or altered. Communication paths ...Rule High Severity -
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
