synflood

Explanation

The synflood security event in the Netography Fusion Portal is designed to detect SYN flood attacks on a network. A SYN flood is a type of DDoS attack where the attacker sends a large number of SYN packets to a target machine in an attempt to overwhelm it and make it unresponsive.

What to Look For

If the synflood event is triggered, it indicates that there may be a SYN flood attack underway on the network. It is important to examine the traffic to determine the source and destination of the packets in question. Additionally, monitoring endpoint performance may be useful in identifying which endpoints are being targeted by the attack. It is recommended to take immediate action to block the offending traffic and protect the network infrastructure.
