Ensure 'SSH source restriction' is set to an authorized IP address

HochStufe 1Automatisiertcisco-asa

Beschreibung

Determines the client IP addresses that are allowed to connect to the security appliance through SSH. One key element of securing the network is the security of management access to the infrastructure devices. It is critical to establish the appropriate controls in order to prevent unauthorized access to infrastructure devices. Fails if no 'ssh <ip> <mask> <ifname>' source restriction exists or SSH is allowed from 0.0.0.0 0.0.0.0 / ::/0. Audited against the output of 'show running-config' (run 'terminal pager 0' first; 'more system:running-config' also works and shows unmasked secrets).
