Distributed Denial-of-Service (DDoS) Attack

Context

To counter the surge in cyberattacks on Indian digital entities following the Pahalgam terror attack, the Computer Emergency Response Team (CERT-In), has issued special instructions to financial institutions and critical sectors to strengthen their cyber defences. Most recent cyber incidents have involved distributed denial-of-service (DDoS) attacks and attempts to deface Indian websites.
