What is the name given to a denial of service attack that consumes resources on a device by creating too many unacknowledged TCP sessions?
Correct Answer: A
Explanation: Explanations:This is an attack against a service designed to make the server unavailable. The attack exploits the limitations of the TCP/IP protocol. A client initiates a TCP connection to a server via a request with the SYN flag set in the TCP header, the server tries to contact the source with a SYN/ACK but the real host is unavailable, this makes the 3 way handshake process incomplete. When multiple Syn attacks floods a server, the server will spend all of its time trying to acknowledge these connections, and be unavailable to process legitimate requests.See Page 6.4 of CCSE NG Official Courseware.
