ABSTRACT
Network security is multifaceted. “Networking” itself is about the provision of access to information
assets and, as such, may or may not be secure. “Network security” can be thought of as the provision
of consistent, appropriate access to information and the assurance that information confidentiality and
integrity are maintained, also as appropriate. Contrary to what may seem intuitive, network security is
not simply a technology solution. It involves the efforts of every level of an organization and the
technologies and the processes that they use to design, build, administer, and operate a
secure network.
