Communication Network And Security
Network security has transformed more important to personal computer users, organizations, and the military.
With the advent of the internet, security became a major concern and the history of security allows a better understanding of
the emergence of security technology. The internet structure itself allowed for many security threats to occur. The
architecture of the internet, when modified can reduce the possible attacks that can be sent across the network. Knowing the
attack methods, allows for the appropriate security to emerge.
Numerous industries secure themselves from the internet by means of firewalls and encryption mechanisms. The businesses
create an “intranet” to remain connected to the internet but secured from possible threats. The entire field of network
security is vast and in an evolutionary stage. The range of study encompasses a brief history dating back to internet’s
beginnings and the current development in network security. In order to understand the research being performed today,
background knowledge of the internet, its vulnerabilities, attack methods through the internet, and security technology is
important and therefore they are reviewed.
