Which type of malware replicates itself to spread rapidly through a computer network?
A worm is a type of malware that replicates itself in order to spread rapidly through a computer network. Unlike viruses, which need to attach themselves to an existing program and require user interaction to propagate, worms are standalone programs that can self-replicate and move across networks without any user action. This autonomy allows worms to spread much more quickly compared to other types of malware.
Both Virus and Worm are self replicating, so C and D
Virus does not fit the definition of "Replicating to spread itself through the network" through
Viruses: A virus is a small piece of software that piggybacks on real programs. For example, a virus might attach itself to a program such as a spreadsheet program. Each time the spreadsheet program runs, the virus runs, too, and it has the chance to reproduce (by attaching to other programs) or wreak havoc. Worms: A worm is a small piece of software that uses computer networks and security holes to replicate itself. A copy of the worm scans the network for another machine that has a specific security hole. It copies itself to the new machine using the security hole, and then starts replicating from there, as well. Viruses have to attach themselves to something else AND someone click on them to replicate. Worms just replicate by themselves EVERYWHERE.
Answer is D - key piece of information is the rapid pace it can replicate, page 33 sg ● Worms: A worm is malware that typically targets a computer network by replicating itself to spread rapidly. Unlike viruses, worms do not need to infect other programs and do not need to be executed by a user or process.
answer: D The primary difference between a virus and a worm is that viruses must be triggered by the activation of their host; whereas worms are stand-alone malicious programs that can self-replicate and propagate independently as soon as they have breached the system.
A worm replicates through the network while a virus replicates, not necessarily to spread through the network.
