Description
Device management includes the ability to control the number of administrators and management sessions that manage a device. Limiting the number of allowed administrators and sessions per administrator based on account type, role, or access type is helpful in limiting risks related to denial-of-service (DoS) attacks. This requirement addresses concurrent sessions for administrative accounts and does not address concurrent sessions by a single administrator via multiple administrative accounts. The maximum number of concurrent sessions should be defined based on mission needs and the operational environment for each system. At a minimum, limits must be set for Secure Shell (SSH), Hypertext Transfer Protocol Secure (HTTPS), and account of last resort.
