Posterous faced Denial of Service Attack !!!

       By a cool afternoon when i logged in to my mail box, i found a mail from Posterous,  a blogging platform. A cool one about this platform is that, posts will blogged through emails to a single email id, post@posterous.com . And the mail is nothing but about the attack they had for one week on their servers.  The Cofounder & CEO of Posterous Mr.Sachin Agarwal was gentle enough to apologize for the inconvenience that happened to all our users for the last one week. He has briefly mentioned about the attack that they faced on their servers. It is all about DENIAL OF SERVICE ATTACK !!! or DoS Attack ... And when i googled about this particular attack, i found the following,

      

            A denial-of-service attack (DoS attack) or distributed denial-of-service attack (DDoS attack or ) is an attempt to make a computer resource unavailable to its intended users. Although the means to carry out, motives for, and targets of a DoS attack may vary, it generally consists of the concerted efforts of a person or people to prevent an Internet siteservice from functioning efficiently or at all, temporarily or indefinitely. Perpetrators of DoS attacks typically target sites or services hosted on high-profile web servers such as banks, credit card payment gateways, and even root nameservers. The term is generally used with regards to computer networks, but is not limited to this field, for example, it is also used in reference to CPU resource management.

                   One common method of attack involves saturating the target (victim) machine with external communications requests, such that it cannot respond to legitimate traffic, or responds so slowly as to be rendered effectively unavailable. In general terms, DoS attacks are implemented by either forcing the targeted computer(s) to reset, or consuming its resources so that it can no longer provide its intended service or obstructing the communication media between the intended users and the victim so that they can no longer communicate adequately.

But after these six rocky days, Posterous is pretty confident to prove them 100% since they have moved thier data centre to a new place. Attacks are common nowadays. Either server attacks or desktop attack,  it is the responsibility of the owners to take care...
