Traditional UDP flood attack In recent years, more and more attackers use UDP reflection amplification attacks. UDP reflection amplification attacks have two characteristics: attacks are UDP-based and the port number of the attack target is fixed. The underlying principles of different types of UDP ...
AH and ESP can be used independently or together. When AH and ESP are used together, ESP encapsulation is performed before AH encapsulation, and AH decapsulation is performed before ESP decapsulation. What Ports Are Used in IPsec? In IPsec, the IKE protocol uses UDP port 500 to initiate and...
Port numbers. Each port is assigned a unique number, ranging from 0 to 65535, which identifies the type of service or application. For example, HTTP typically uses port 80, while HTTPS uses port 443. TCP and UDP protocols.Ports operate using either the transmission control protocol (TCP) or...
