Management and Security
The Cisco IOS software provides an array of network management
and security capabilities. Integrated management simplifies adminis-
trative procedures and shortens the time required to diagnose and fix
problems. Automated operations reduce hands-on tasks and make it
possible to manage large, geographically dispersed internetworks with
a small staff of experts located at a central site.
The Cisco IOS software provides several management features includ-
ing configuration services, which lower the cost of installing, upgrad-
ing, reconfiguring routers, and reconfiguring access servers, as well as
comprehensive monitoring and diagnostic services. In addition, the
Cisco IOS software provides information and services for router man-
agement applications.
Management services are matched by their security capabilities. Th
Cisco IOS software includes a diverse tool kit for partitioning re-
sources and prohibiting access to sensitive or confidential information
and processes. Multidimensional filters prevent users from knowing
that other users or resources are on the network. Encrypted passwords,
dial-in authentication, multilevel configuration permissions, network
data encryption, and accounting and logging features provide protec-
tion from and information about unauthorized access attempts and data
eavesdropping attempts.
