Sophisticated attack tools and open networks continue to generate an increased need for network security policies and infrastructure to protect organizations from internally and externally based attacks.

Organizations must balance network security needs against e-business processes, legal issues, and government policies. Establishing a network security policy is the first step in changing a network over to a secure infrastructure.

Network adversaries come in many shapes and sizes and with multiple motivations.

It is very important to provide physical installation security for enterprise network devices.

Password attack threats can be mitigated.
-Restrict password use.
-Disable accounts after unsuccessful logins.
-Do not use cleartext passwords; use strong passwords.
