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 reques

Another form of denial of service attack can come in the form of mail bombs. Mail bombs are when someone sends huge amounts of mail to a company's server. This clogs up the system because most servers are not equipped to handle this overabundance of mail. This is one of the more primitive forms of denial of service attack, however it remains to be effective for the malicious individual. The damage that this form of attack causes is usually not as severe as the others mentioned, but includes the server not being able to receive legitimate mail and important information can be lost that way. Also service from that server can be halted.

any legitimate client or customer cannot connect to that server. This form of attack incapacitates the company's server eliminating all potential business.

Cyber Vandalism is a serious problem in the e-commerce environment. Cyber Vandalism is when someone breaks into a web company's server and defaces it. Hackers have found ways to alter legitimate web pages to display other pages or have put pornographic or political messages on them. They have also been known to change the company's web page all together so it simply displays one page containing some message or picture with no links to other areas of the site. This can render the site useless or can cause potential clients to leave the site.

ber. The receiving machine accepts this because it thinks it is coming from the legitimate sender. This requires sophisticated software and is not highly likely to occur. If it does though, an attacker can send viruses over this connection or can simply gain complete access to the receiving site, jeopardizing critical private information and the server itself. Once the connection is hijacked the attacker can also delete essential files or introduce malicious code causing the system to crash.

Sniffer programs are programs that monitor all the information that passes a certain point on the Internet. This point is often a distinct router or server, along the path a message takes from one source to another. A lot of this information is useless to anyone but whom the message was intended to reach but there is also a lot of information, which a potential evildoer could use against a company. For example, companies often release critical private information dealing with key business decisions like mergers and
