The increasing importance of networked control systems makes them inviting targets for cyber attacks. In a virus propagation attack, an adversary attempts to compromise a set of nodes in order to compromise their neighbors via software exploits. When the neighbor of a compromised node has already been compromised by a different virus, a newly-introduced virus can remove, co-exist with, or reinforce...
Viral propagation modelling acts as sandbox for testing intensity of malware, understand patterns adopted for malware propagation and consequently help device strategies for malware detection. Success of P2P networks has encouraged mobile vendors to offer P2P services on mobile networks. Handheld mobile devices though constrained in memory, power and processing resources are capable of using communication...
Sequence alignment is widely used in bioinformatics for revealing the genetic diversity of organisms and annotating gene functions by finding regions of similarity across biosequences. Such alignment requires sequences to be represented in the DNA or protein alphabet for tools such as Clustal to work. Previous work has demonstrated the feasibility of applying biosequence multiple alignment techniques...
Malware is currently a major threat to information and computer security, with the volume and growing diversity of its variants causing major problems to traditional security defenses. Software patches and upgrades to anti-viral packages are typically released only after the malware's key characteristics have been identified through infection, by which time it may be too late to protect systems. Multiple...
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...
