Computer security is the process
of preventing and detecting unauthorized use of your
computer. Prevention measures help you to stop unauthorized
users (also known as "intruders") from accessing any part of
your computer system. Detection helps you to determine
whether or not someone attempted to break into your system,
if they were successful, and what they may have done.
The rapid growth in mobile
users, external workers, and partners demands a centralized
approach to setting access policies. Converged applications
introduce the need to protect voice, data, and video. Public
and home wireless LANs spell greater vulnerability.
Historically, IT
departments have built networks to link internal resources
that are protected from the outside world. So we develop a
solid framework for converged network services that puts
security at the forefront of network architecture and makes
the benefits available to each solution. |
