Computer Crime and Computer Forensics

 

INTRODUCTION

 

Computer crime has become a very large issue in society today; computer criminals cost companies across the world billions of pounds every year. This essay will discuss many of the main cyber crimes and the principles and practises associated with investigating computer crime in general. Computers are ever-present with modern organizations and it is inevitable that illegal activities will involve computers. Threatening letters, fraud, and theft of intellectual property are all crimes that leave digital tracks. "Investigations into these types of crimes usually include searching computers that are suspected to be involved in their commission" [1]. Such analysis involves sifting through gigabytes of data, looking for specific keywords, examining log files to see what happened at certain times, and hopefully providing evidence that a specific person committed a specific criminal act. "The authoritative CSO Magazine eCrime Watch Survey estimated that the cost to US organisations alone was $666 million in 2003" [2]. This means that cyber crimes cost US organizations nearly $2 million every day and these organizations have been forced to vastly modify there security system in order to protect themselves. Most companies no longer solely rely on law enforcement to protect themselves from cyber-terrorists. Often convicted cyber criminals are hired to act as a security professional. This practise is sometimes referred to as "hiring a hacker" [3], and to management, it may appear to be a drastic defence against potential attacks. It is a perfectly logical and intelligent solution to an ever-growing problem in Web application development. Security professionals may be brought on as full-time employees, but mostly they are contracted to perform security audits, return results to the appropriate personnel and make suggestions for improving the current security situation. In larger organizations, a security expert is more likely to be hired as a full-time employee remaining on staff within the IT department.


WHAT MOTIVATES A HACKER?

"Notoriety, challenge, boredom and revenge are just a few of the motivations of a hacker." [3]. Mostly hackers are breaking into something so that they can say they did it. Another reason is that hacking is an intellectual challenge. "Discovering vulnerabilities, researching a mark, finding a hole nobody else could find." [3]. The draw that hacking has for programmers eager to accept a challenge is evident in the number and popularity of organized competitions prearranged by the hacking conferences (e.g. Security Depot Online [4]) and software companies. Boredom is another significant reason for hacking. Hackers often just look around to see what sort of forbidden things they can access. Finding a target is often a result of coming across vulnerability, not seeking it out in the first place. Revenge hacking occurs because someone, somewhere, somehow made the wrong person mad. This is common for employees who were laid-off and are now seeking revenge with their previous employer. Revenge hacking is probably the form of hacking for most companies, as a former employee may have vast knowledge of the code and network, among many other forms of protected information. "As an employer, the time to start worrying about someone hacking into your computer system is not after you let one of the network engineers or developers go. You should have a security plan in place long before that day ever arrives." [3].
