Detect and deter synflood attacks using an open source software program.
The primary goal of SynDetector is to detect and break synflood attacks, which can essentially overload a server with a flood of start of connections (syn packet). This can make it nearly impossible for legitimate clients to connect to the server, which can be quite problematic for businesses of all sizes.
When a server receives a SYN packet, it will respond with a SYN-ACK to the client. In order to establish the connection, the client must then send an ACK back to the server. If the client ignores or cannot respond to the SYN-ACK, the needed capacity can quickly be exceeded, which can cause significant problems for businesses and organizations.
To address this issue, SynDetector is designed to detect and ban IP addresses where attacks originate, essentially blocking the SYN packets and preventing them from reaching the server. The software also has the capacity to detect and block a derivative of the synflood attack, which involves saturating a particular service (e.g. Apache) with a flood of connections.
While this type of attack can come from legitimate IP addresses and is not as easy to detect or block, SynDetector can help identify and mitigate the issue before it leads to significant damage. Keep in mind, however, that this type of attack is typically used by inexperienced or amateur hackers, so the risk of a successful attack is relatively low. Overall, if you're looking for an effective way to protect your server from synflood attacks, SynDetector is definitely worth considering.
