The Denial of Service Attacks

             One of the most common attacks on insecure e-commerce systems comes in the form of denial of service attacks. Denial of service attacks can literally overload a server to the point where it can no longer function. This shutdown halts all business transactions that were taking place at the time, and does not allow for potential transactions. When a company's computers are clogged up by this form of attack they lose profits and business just as they would, had it been a traditional store that had to close its doors. There are a few different kinds of denial of service attacks. They all are malicious and are intended to harm the site they are aimed at.
             The most common form of this attack is known as a SYN Flood. SYN stands for synchronize sequence number. A SYN Flood starts when a malicious computer creates a TCP connection with the intended site. This connection originates as a request for information from that site's server and contains an ID that tells the server where to send that requested information. Normally the server would respond to the request by sending an acknowledgement back to the computer, which originally sent the ID. When the acknowledgement is confirmed the server then sends the requested information to their computer. When the SYN Flood attack happens however, the computer contacting the server sends it requests with false ID's over and over. The server can not get the acknowledgement that it needs to send the information back to the requesting computer, and the connection stays open until it times out. When this process is repeated over and over the server uses up all of its possible connections, and any legitimate client or customer cannot connect to that server. This form of attack incapacitates the company's server eliminating all potential business.
             Another form of Denial of service attack uses PING. PING stands for packet Internet groper and what it does is checks whether a server is working or not and al...
