Explanation:
: VPN1-FW1 NG´s SynDefender stop SYNFlood attacks, it provides two defenses against it, a
“SynDefender Gateway” and “SynDefender Passive Gateway”, both of this are integrated with the
Inspect module of the enforcement modules. Just to remember, the SYN flood attack never
completes the third step of the 3 way TCP handshake, it never sends the ACK, this makes the
attacked server to allocate memory to connections that will never be completed, with thousands of
this uncompleted connections the protocol stack at the server gets and overflow and crash the
O.S. The SYN Flood is considered a DoS attack, it can be used in conjunction of other attacks like
IP spoofing .
