Securing Cisco Router Installations

Insecure installation of network routers and switches is an often-overlooked security threat, which, if left unheeded, can have dire results. Software-based security measures alone cannot prevent premeditated or even accidental network damage due to poor installations. This section discusses ways to identify and remedy insecure installations.
