What type of attack involves overwhelming a system with fake traffic to make a machine or network resource temporarily unavailable to intended users?

Correct option is C

A Distributed Denial of Service (DDoS) Attack is a type of cyber attack in which a system is bombarded with excessive fake traffic, rendering it inaccessible to legitimate users. This attack often involves multiple sources to flood the network or system, overwhelming it with requests and causing service disruption.
Important Key Points:
1. Traffic Overload: DDoS attacks aim to overload a system, causing legitimate traffic to be blocked or slowed down.
2. Temporary Unavailability: These attacks make network resources temporarily inaccessible.
3. Multiple Sources: Often, DDoS attacks use botnets or multiple devices to create massive fake traffic.
Knowledge Booster:
· Network Intrusion: Refers to unauthorized access to a network but doesn’t involve fake traffic overload.
· Malware Injection: Involves inserting malicious code but not specifically overwhelming with fake traffic.
· Phishing Attack: Targets users by tricking them into revealing sensitive information; does not involve traffic overload.
· Man-in-the-Middle Attack: Involves intercepting communication between two parties, not necessarily causing system unavailability.
