UGC NET Questions (Paper – 1)

Statements A, B and C accurately describe common security threats, whereas D is dangerous and false. Phishing, shoulder surfing and keyloggers are all techniques used to steal information by deception or covert surveillance. Downloading software from untrusted sources increases the risk of malware infection instead of improving security. Thus, the combination A, B and C only is the correct answer.

Option A:
Option A is incomplete because it includes only A and B and ignores C. While phishing and shoulder surfing are important threats, keyloggers are also a significant risk that learners need to recognise. Excluding C leaves the list of threats incomplete.

Option B:
Option B is correct because it gathers all three true statements and rejects D, which contradicts basic security guidelines. It reinforces the need for cautious behaviour and awareness of multiple attack vectors in ICT environments.

Option C:
Option C is incomplete because it lists only B and C as correct, omitting A. Phishing is one of the most prevalent online attacks, and leaving it out fails to provide a comprehensive picture of security threats.

Option D:
Option D is incorrect because it mixes A and C with D and therefore accepts D. Recommending unverified software installation contradicts best practices and may itself facilitate attacks, so this option cannot be accepted.
