How to protect SYN Flood Attacks or DDos Attacks

[dudarra]

Hey Guys,

Can someone guide me how to protect SYN Flood Attacks or DDos on the Fortigate Loadbalancer?

I need to know how an attack can prevent or defend.

There are a lot of things you can do to prevent attacks. To prevent SYN attacks, you can increase the limit of a backlog so that it would avoid the denying of legitimate connections. Another approach of SYN attack protection is reusing the memory of the SYN backlog by deleting the oldest half-open association.The next SYN flood attack mitigation strategy involves the concept of cookies. For more information about all these methods, try contacting an IT support company, like https://www.solutions4it.co.uk/branches/.
