Sources of Security Threats
The security threat to computer systems springs from a number of factors that
include:
Weaknesses in the network infrastructure and communication protocols that create an appetite and a challenge to the hacker mind.
The rapid growth of cyberspace into a vital global communication and business
network on which international commerce and business transactions are increasingly being performed and many national critical infrastructures are being connected.
The growth of the hacker community whose members are usually experts at gaining unauthorized access into systems that run not only companies and governments but also critical national infrastructures.
The vulnerability in operating system protocols whose services run the computers that run the communication network.
The insider effect resulting from workers who steal and sell company databases and the mailing lists or even confidential business documents;
Social engineering.
Physical theft from within the organizations of things such as laptop and handheld computers with powerful communication technology and more potentially sensitive information;
Security as a moving target.
Rapid Growth of Cyberspace
There is always a security problem in numbers. Since its beginning as ARPANET in the early 1960s, the Internet has experienced phenomenal growth, especially in the last 10 years. There was an explosion in the numbers of users, which in turn ignited an explosion in the number of connected computers.
Just less than 20 years ago in 1985, the Internet had fewer than 2000 computers connected, and the corresponding number of users was in the mere tens of Security Threats and Threat Motives to Computer Networks 67 thousands. However, by 2001, the figure has jumped to about 109 million hosts, according to Tony Rutkowski at the Center for Next Generation Internet, an Internet Software Consortium. This number represents a significant new benchmark for the number of Internet hosts. At a reported current annual growth rate of 51% over the past 2 years, this shows continued strong exponential growth, with an estimated growth of up to 1 billion hosts if the same growth rate is sustained.
This is a tremendous growth by all accounts. As it grew, it brought in more and
more users with varying ethical standards, added more services, and created more responsibilities. By the turn of the century, many countries found their national critical infrastructures firmly intertwined in the global network. An interdependence
between humans and computers and between nations on the global network has been created that has led to a critical need to protect the massive amount of information stored on these network computers. The ease of use of and access to the Internet and large quantities of personal, business, and military data stored on the Internet was slowly turning into a massive security threat not only to individuals and business interests but also to national defenses.
As more and more people enjoyed the potential of the Internet, more and more people with dubious motives were also drawn to the Internet because of its enormous wealth of everything they were looking for. Such individuals have posed a potential risk to the information content of the Internet, and such a security threat has to be dealt with.
Statistics from the security company Symantec show that Internet attack activity is currently growing by about 64% per year. The same statistics show that during the first 6 months of 2002, companies connected to the Internet were attacked, on average, 32 times per week compared to only 25 times per week in the last 6 months of 2001. Symantec reports between 400 and 500 new viruses every month and about 250 vulnerabilities in computer programs.
In fact, the rate at which the Internet is growing is becoming the greatest security threat ever. Security experts are locked in a deadly race with these malicious hackers that, at the moment, looks like a losing battle with the security community.
