DoDI 8500.2 IA controls IAIA-1 and IAIA-2 state, in part: “Ensure all factory set, default, standard or well-known user-IDs and passwords are removed or changed.”
Factory default, well-known, and/or manufacturer backdoor accounts and their associated passwords provide easy unauthorized access to system/device. Leaving such accounts and passwords active on a system/device makes it extremely vulnerable to attack and/or other unauthorized access. As such, they need to be removed, changed, renamed, or otherwise disabled.
Also covered by this policy are “community strings”, which act as passwords for monitoring and management of network devices and attached systems via SNMP. The universal default SNMP community strings are “public” and private” and are well known.
Default access for VTC operation, local and remote control, and management/configuration purposes is typically unrestricted or minimally protected by well known and well published default passwords. It has been demonstrated that not changing these passwords is the most common cause of VTC system compromise.
