[#306] The majority of computer crimes are committed by:
Correct Answer
(B) Insiders
Explanation
Solution: An insider threat is a malicious threat to an organization that comes from people within the organization, such as employees, former employees, contractors or business associates, who have inside information concerning the organization's security practices, data and computer systems. The threat may involve fraud, the theft of confidential or commercially valuable information, the theft of intellectual property, or the sabotage of computer systems. The insider threat comes in three categories: I. Malicious insiders, which are people who take advantage of their access to inflict harm on an organization. II. Negligent insiders, which are people who make errors and disregard policies, which place their organizations at risk. III. Infiltrators, who are external actors that obtain legitimate access credentials without authorization.
[#307] The thing that eventually terminates a worm virus is a lack of:
Correct Answer
(A) Memory or disk space
Explanation
Solution: The correct answer is A: Memory or disk space . Let's break down why: A worm virus is a type of malware that self-replicates and spreads to other computers on a network. Unlike a regular virus, it doesn't need to attach itself to a host program. It does this by consuming resources like memory and disk space . Eventually, a worm can exhaust these resources to the point where the system becomes slow or unusable, and it can no longer replicate and spread. Option B: Time is incorrect because time itself doesn't limit a worm. Worms can continue to replicate as long as resources are available. Option C: CD drive space and Option D: CD-RW are incorrect because worms primarily spread through networks and use system resources, not necessarily CD drives. Therefore, the lack of memory or disk space is the most direct factor that eventually terminates a worm virus.
