A1 and 4 only

B1 and 3 only

C2 and 4 only

D2 and 3 only ✓ Correct

Correct answer: (D) 2 and 3 only

Explanation

CERT-In acts as India's early-warning system that issues alerts and advisories on cyber threats and attacks, which is statement 2.

Tor stands for The Onion Router, browsing software that lets people communicate online anonymously, which is statement 3.

Statement 1 is wrong because incident response deals with detecting and containing an attack after it occurs, not closing vulnerabilities beforehand.

Statement 4 overstates matters because a VPN encrypts data on a connection between endpoints rather than securing a whole network by itself.

Prevention before an attack is the job of vulnerability management, a separate activity from incident response.

CERT-In was established in 2004 as the national nodal agency for cyber security incidents.
