Technical Terms - Internet (A-Z) - Denial of Service

What is the main goal of a denial of service attack?

• To make computer systems unavailable

• To enhance website security

• To steal personal information

• To improve server performance

Which type of servers are typically targeted in a denial of service attack?

• DNS servers

• FTP servers

• Web servers

• Database servers

What is the difference between a DoS attack and a DDoS attack?

• DoS attacks target web servers, while DDoS attacks target mail servers

• DoS attacks are illegal, while DDoS attacks are legal

• DoS attacks use a single machine, while DDoS attacks use multiple machines

• DoS attacks are more effective than DDoS attacks

How do DDoS attacks coordinate multiple systems in a simultaneous attack?

• By telling all systems to send requests to a specific server at the same time

• By using a single powerful server to send requests

• By targeting different servers at different times

• By encrypting the requests to avoid detection

What happens if a server cannot respond to the large number of simultaneous requests in a DDoS attack?

• The server will block all incoming requests

• The server will shut down immediately

• The requests will be redirected to another server

• Incoming requests will eventually become queued

Why are DoS attacks a common method used by hackers to attack websites?

• Flooding a server with requests does not require authentication

• Hackers find DoS attacks too challenging

• DoS attacks are impossible to detect

• Websites have strong immunity against DoS attacks

What is a botnet used for in the context of a DoS attack?

• To provide authentication for the attack

• To control multiple computers at once

• To enhance server performance

• To encrypt the attack requests

How do security software developers limit the effectiveness of DoS attacks?

• By detecting DoS attacks and updating security systems

• By increasing the server's response time

• By shutting down the servers permanently

• By blocking all incoming traffic

Which well-known websites have been targets of denial of service attacks in the past?

• Google, Twitter, and WordPress

• Netflix, Hulu, and Spotify

• Facebook, Instagram, and LinkedIn

• Amazon, eBay, and Alibaba

What is the purpose of updating security systems after a DoS attack?

• To increase the number of incoming requests

• To prevent further service interruptions

• To encourage more DoS attacks

• To make the server more vulnerable
