¶ Why Port 0?
Port 0/UDP is a port that uses the UDP protocol and that there is no service or application associated with it, so it is practically used to generate Denial-of-Service (DoS) attacks.
In our analyses with various providers, we noticed that several ISPs have received a lot of traffic through Port 0/UDP.
¶ Main uses of this dashboard?
To analyze whether your network needs to implement attack protection mechanisms using port 0/UDP
Analyze whether port-0 attacks happen from the inside out (Generating attack) or outside in (Receiving attack).
¶ How to access this dashboard?
Access the menu -> Analyzes
Then in Door 0
¶ What information does this report show me?
The first graph shows the total inbound and outbound traffic for Port 0/UDP:
The next piece of information we have is a raw data report demonstrating the IPs that generated/received the attacks on Port 0:
In this part of the dashboard, we have the Top interfaces that were attacked on port 0:
In the router view, you can see by router which one is generating/receiving attack and view through each interface within the Router:
By clicking on the Router you can see the information by interface:
