The biggest Distributed Denial-of-Service (DDoS) attack occurred in February 2018. The victim was GitHub and at its peak, this attack saw incoming traffic at a rate of 1.3 terabytes per second (Tbps). By taking down the website, a DDoS attack not only leads to loss of revenue but also affects the company's reputation.
A DDoS attack or Denial of service attack is aimed at bringing your website down by overwhelming it with traffic more than the network can afford.
Therefore, it is crucial to have a plan before a DDoS attack strikes. The plan must properly document the network topology diagram for management of crucial assets during the attack and require the alerting of relevant stakeholders. A few other tricks for preparing for a DDoS attack include the use of sufficient bandwidth, infrastructure redundancy, DNS server redundancy and use of WAF (web application firewalls) for server protection.
