Fortifying Network Security: The Power of Blackhole Routing in Mitigating DoS Attacks
Objective of Blackhole in ISP :- A black hole, in the context of Internet Service Providers (ISP), is a measure to deal with traffic that is flooding network causing congestion by discarding this type of traffic. With the Black Hole route it is a simple matter of redirecting traffic intended for an IP address (or range) to a non-existent path or "null" interface, in doing so the malicious traffic is stopped from getting to its target and killing off network completely. It helps in preserving network stability and Execution by isolating the attackers or risky data flows from authentic customers. However, this inevitably leads to a loss of legitimate and good traffic destined for the black holed IP addresses, so black holing is more of a tactical solution than sustainable one.
