Network
security has become 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. Many
businesses
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.
The world
is becoming more interconnected with the advent of the Internet and new
networking technology. There is a large amount of personal, commercial,
military, and government information on networking infrastructures worldwide.
Network security is becoming of great importance because of intellectual
property that can be easily acquired
through the
internet. There are currently two fundamentally different networks, data
networks and synchronous network comprised of switches. The internet is
considered a data network. Since the current data network consists of
computer‐based routers, information can be obtained by special programs, such
as “Trojan horses,” planted in the routers. The synchronous network that
consists of switches does not buffer data and therefore are not threatened by
attackers. That is why security is emphasized in data networks, such as the
internet, and other networks that link to the internet. The vast topic of
network security is analyzed by researching the following:
1. History
of security in networks
2. Internet
architecture and vulnerable security aspects of the Internet
3. Types of
internet attacks and security methods
4. Security
for networks with internet access
5. Current
development in network security hardware and software
Based on
this research, the future of network security is forecasted. New trends that
are emerging will also be considered to understand where network security is
heading.
Network
security is an important field that is increasingly gaining attention as the
internet expands. The security threats and internet protocol were analyzed to
determine the necessary security technology. The security technology is mostly
software based, but many common hardware devices are used. The current
development in network security is not very impressive.
Originally
it was assumed that with the importance of the network security field, new
approaches to security, both hardware and software, would be actively
researched. It was a surprise to see most of the development taking place in
the same technologies being currently used. The embedded security of the new
internet protocol IPv6 may provide many benefits to internet users. Although
some security issues were observed, the IPv6 internet protocol seems to evade
many of the current popular attacks. Combined use of IPv6 and security tools
such as firewalls, intrusion detection, and authentication mechanisms will
prove effective in guarding intellectual property for the near future. The
network security field may have to evolve more rapidly to deal with the threats
further in the future.
