CISC-ND-000010 - The Cisco switch must be configured to limit the number of concurrent management sessions to an organization-defined number - ip http max connections
Information
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 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 upon mission needs and the operational environment for each system. At a minimum, limits must be set for SSH, HTTPS, account of last resort, and root account sessions.
Solution
Configure the switch to limit the number of concurrent management sessions to an organization-defined number as shown in the example below:SW4(config)#ip http max-connections 2
SW4(config)#line vty 0 1
SW4(config)#transport input ssh
SW4(config)#line vty 2 4
SW4(config)#transport input none
