ntpreflect

Explanation

The ntpreflect event in Netography Fusion Portal looks for an NTP reflection attack. This is a type of DDoS attack in which an attacker sends a request to an NTP server and spoofs the source IP address to make it appear as if the request originated from the target server. The NTP server then responds to the target server, flooding it with traffic.

What to Look For

In order to examine the results of the ntpreflect event, customers should look for traffic originating from NTP servers that they do not control, and an unusually high amount of traffic to their own servers. Users should examine network logs and check endpoint logs for any signs of suspicious activity related to NTP servers. This event can help prevent NTP reflection attacks on a network, ensuring security.
