What is a DoS or DDoS attack?

Denial of service attack (DoS attack) or distributed denial of service attack (DDoS attack) is a type of external Internet attack, in which multiple sources attack a single target computer system causing a Denial of Service (DoS) attack, with the goal being denial of service for its users.

Normally, DDoS attacks flood the target computer system with incoming messages at a rate much higher than it can process, which will slow down the target system to a level where it is rendered useless to users or making target system crash and become unusable.

How to deal with a DDOS attack ?

DDoS attacks are frustrating for the company under attack, which can also be costly in terms of business. There is no perfect solution to prevent DDoS attack.

  • Wait for the attack to subside( find out who is targeting the site, filter attack data and prevent them acting).
  • Have extra servers that can divert the “syn flood” away from the main site while allowing legitimate requests through.
