Security is a very difficult topic. Everyone has a different idea of what ``security'' is, and
what levels of risk are acceptable. The key for building a secure network is to define
what security means to your organization . Once that has been defined, everything that
goes on with the network can be evaluated with respect to that policy. Projects and
systems can then be broken down into their components, and it becomes much simpler
to decide whether what is proposed will conflict with your security policies and practices
(Curtin, 1998).
Security systems have different security levels, based on the types and sensitivity of
data. Besides obvious network security like ID's and passwords, encryption, key cards,
etc. I believe additional security issues to consider are the following:
Firewalls, proxy servers, or gateway configuration.
Access Control Lists (ACLs) formation and implementation.
SNMP configuration and monitoring.
Security hot fixes to software of various devices, operating systems, and
applications.
Backup and restore procedures.
