Description: SYN Flood Protection is a security feature implemented in firewalls aimed at mitigating SYN flood attacks, a type of denial-of-service (DoS) attack. This type of attack is based on the TCP protocol, where an attacker sends a large number of SYN packets to a server, causing the server to attempt to establish connections that are never completed. This can lead to server saturation, preventing it from handling legitimate requests. SYN flood protection limits the number of half-open connections, meaning those that have received a SYN packet but have not been completed with an ACK packet. By setting a threshold for these connections, the firewall can reject new connection requests once the limit is reached, helping to maintain service availability and protect network infrastructure. This feature is essential in environments where service availability and continuity are critical, such as web servers, cloud applications, and data management systems. Implementing this protection enhances security and optimizes server performance by preventing it from being overwhelmed by malicious traffic.
