Correct Answer: B,E
SYN flood and teardrop are two types of denial-of-service (DoS) attacks, which aim to disrupt the availability of a service or a system by overwhelming it with malicious traffic or requests. A SYN flood attack exploits the TCP three-way handshake process by sending a large number of SYN packets to the target's port, without completing the connection. This causes the target to allocate resources for half-open connections, eventually exhausting its memory or bandwidth. A teardrop attack exploits the IP fragmentation process by sending malformed or overlapping IP fragments to the target, causing it to crash or reboot when trying to reassemble them.
