Incomputing, adenial-of-service attack(DoS attack) is acyber-attackin which the perpetrator seeks to make a machine or network resource unavailable to its intendedusersby temporarily or indefinitely disruptingservicesof ahostconnected to theInternet. Denial of service is typically accomplished by flooding the targeted machine or resource with superfluous requests in an attempt to overload systems and prevent some or all legitimate requests from being fulfilled.
In adistributed denial-of-service attack(DDoS attack), the incoming traffic flooding the victim originates from many different sources. This effectively makes it impossible to stop the attack simply by blocking a single source.
A DoS or DDoS attack is analogous to a group of people crowding the entry door of a shop, making it hard for legitimate customers to enter, thus disrupting trade.
