Detection and removal of malware infections have always been significant concerns for every computer user. Countless people are victims of malicious programs per day all around the world despite substantial improvements in malware defense. Developing techniques to characterize the harm caused by these programs enables new defenses to counteract these behaviors. One way to create these metrics is to...
We consider a discrete-time model for the spread of computer viruses in a network where the number of times the network can be fixed (i.e., the malware is reduced to a baseline level) is limited. The model consists of a set of viruses which may strike (attempt to infect) the system at each time with fixed probability. Once a virus strikes, it may go on to infect a node with some probability which...
This paper presents the generation of virus emerging from email to cellphones. Most of these early threats were self-replicating but not self-transporting, spreading from computer to computer via infected floppy disks. As more viruses were discovered, most known malware existed only in researchers' collections and not in users' machines. Malware was shift from virus to worm called Trojan horse. And...
The surveys were conducted to compare the knowledge and experience of students of five Korean universities and three US universities with various forms of malware. The study included an empirical assessment of the cross-cultural similarities and differences between students in the two countries. The variables examined include knowledge of computer viruses, spyware, and rootkits as well as perceptions...
Threats to information security are spreading, from both outside and within an organization. Computer security has evolved so as the methods of identification, detection, and prevention of malware, only to be followed by a new set of threats that circumvent those safeguards. Internet and wide availability of toolsets and documentation exacerbates this problem by making malware development easy. As...
