DDoS mitigation approaches
DDoS mitigation approaches follow a multi-step process of detection of malicious traffic, followed by scrubbing, rerouting or dropping such traffic. Defining normal "traffic patterns" helps to identify abnormal traffic, and also to differentiate between human and bot traffic. Scrubbing involves running heuristic algorithms on the traffic to detect anomalies. Previously, most of these checks were done in hardware. Today, some of them are also done in software. what is ddos mean ? A technique called "blackhole routing" or "null routing" is used to discard traffic, which might also cause non-malicious traffic to be dropped if there are no filtering criteria. Linode will "block the attack inline, then distribute the increased traffic across its global fiber backbone" in the event of an attack. According to reports, Linode's current solution will adopt null routing if the attack is sufficiently large, and they also recommend using an addition...
