What is DOS attack


  • DoS (Denial of Service) and DDoS (Distributed Denial of Service) are sophisticated threat that are very difficult to detect and eradicated.
  • DoS and DDoS attack an attempt to make an online service unavailable by overwhelming it with an excessive amount of traffic so that it cannot handle it.
  • There area several tools that have made it quite simple to disrupt any website's availability through these attacks.
  • In a Dos attack, legimate users are deprived of access  to a networl or web resource.
  • In DoS,  an attacker creates a program that establishes a connection on a  service port by forging the packet's header details and then leaves the connection..


  • Now if the host can handle 20 requests per second, the attacker sends  50 requests per seconds. This has a high probability of causing the host server to go down due to mass fake requests received which far exceed the maximum volume that it cab handle.
  • DDoS attack is type of cybersecurity threat which target business that offer online services through website.  
  • The attack is to overload these website with traffic from multiple sources and usually with more traffic than that the server can handle.
  • The overload cause website to run slowly for genuine users and, it some case, shutdown a website completely.
  • The primary goal of DDoS attacks is to prevent an organisation from functioning properly and to bring operations to a standstill there by hurting them financially and in term of reputation.
