TAILIEUCHUNG - Network Security: History, Importance, and Future  University of Florida Department of Electrical and Computer Engineering  

Recent interest in security was fueled by the crime committed by Kevin Mitnick. Kevin Mitnick committed the largest computer‐related crime in . history [3]. The losses were eighty million dollars in . intellectual property and source code from a variety of companies [3]. Since then, information security came into the spotlight. Public networks are being relied upon to deliver financial and personal information. Due to the evolution of information that is made available through the internet, information security is also required to evolve. Due to Kevin Mitnick’s offense, companies are emphasizing security for the intellectual property. Internet has been a driving force for data security improvement. Internet protocols in the past were not developed to secure themselves. Within the TCP/IP communication stack, security protocols are not implemented. This leaves the internet open to attacks. Modern developments in the internet architecture have made communication more secure. . | Network Security History Importance and Future University of Florida Department of Electrical and Computer Engineering Bhavya Daya ABSTRACT 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. INTRODUCTION 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.
