Basically DDos attack where attacker Overwhelms the server/services so that legitimate user can not access it. When a client attempts to connect to a server using the TCP protocol e.g (HTTP or HTTPS), it is first required to perform a three-way handshake before any data is exchanged between the two. Since the three-way TCP handshake is always initiated by the client it sends a SYN packet to the server. For download the Metasploitable 2 Virtual Machine:- https://sourceforge.net/projects/meta...
