Answer:
4. A Denial of Service attack (DDOS attack).
Explanation:
A DDOS attack is a malicious attempt to disrupt the normal traffic to a service.
In essence, it sends an enormous amount of requests to the service, until the server is overwhelmed because it can't handle that much traffic, and collapses in an overflow.
Thus, regular users are not able to access their services.
Usually, attackers use a botnet, a network of "zombie" computers that have been previously infected with a malware that allows the attacker to remotely control them, then the botnet starts to send a flood of traffic from different locations, and make the attacker difficult to detect or track.
Answer: (D) Distributed denial- of- service (DDoS)
Explanation:
The distributed denial of service attack is one of the type of attack that occur when the multiple system are basically flooded with the resources and the bandwidth.
- Botnet is one of the example of DDoS as it caused the DOS (denial of service) for the users.
- This type of attack is more substantial as compared to the DoS attack as they use the multiple system for attack the single target simultaneously.
Therefore, Option (D) is correct.
