Technical Terms - Internet (A-Z) - SYN Flood

What does SYN stand for in a SYN flood attack?

• Server

• Synchronize-ACK

• System

• Synchronize

What is the purpose of a SYN-ACK message in the TCP/IP protocol?

• To deny service

• To encrypt data

• To synchronize time

• To establish communication

What happens if a server receives a large number of SYN requests but no ACK messages in a SYN flood attack?

• The server becomes slow or unresponsive

• The server blocks all requests

• The server sends more ACK messages

• The server shuts down

How does server software typically handle SYN flood attacks?

• Amplify them

• Detect and stop them

• Ignore them

• Encourage them

What is a common method used to limit Distributed Denial of Service (DDoS) attacks?

• TCP/IP blocking

• SYN flooding

• ACK messaging

• SYN caching

What does implementing SYN cookies help prevent in a SYN flood attack?

• Server shutdown

• Firewall blocking

• Data encryption

• Resource exhaustion

How does SYN flood protection limit resources for flood attacks?

• By increasing server capacity

• By recording IP addresses

• By blocking all requests

• By sending more SYN requests

What is the purpose of configuring SYN flood protection on a network firewall?

• To increase server speed

• To limit resources used for flood attacks

• To shut down the server

• To allow all requests

What is the main difference between a SYN flood and a DDoS attack?

• Number of IP addresses used

• Size of the server

• Type of messages sent

• Time of day the attack occurs

How can a server detect a SYN flood attack from the same IP address?

• By receiving a large number of SYN requests in a short time

• By blocking all requests

• By increasing server capacity

• By sending more ACK messages
