blackholing and sinkholing security from ravitejafe's blog

Blackhole security and sinkhole security are two different approaches to network defense that are frequently used to combat distributed denial-of-service (DDoS) attacks. Blackhole security involves diverting malicious traffic to a “black hole” or null route, where the traffic is dropped without reaching its destination.

This technique is effective in neutralizing large attack volumes since it does not require additional processing. Sinkhole security involves redirecting malicious traffic to a special server that can analyze the traffic and determine its source before dropping it.

Both approaches offer improved visibility of the attack, enabling analysts to identify malicious hosts and prevent them from communicating with their targets. While both methods are effective in defending against DDoS attacks, they each have their own set of advantages and disadvantages.
