DoS attacks cause more damage than any other attack type, so imagine if your published business portals are subjected to such attack and how this can aﬀect your image with the your customers!
Besides DoS ” or denial of service attacks”, three other damage types can be inﬂicted on a network or its data: data destruction, information disclosure, and data modiﬁcation. So what we are trying to do is ensure Conﬁdentiality (deals with Information Disclosure), Integrity (deals with Data Destruction and Modiﬁcation) and Availability (deals with DoS attacks). This is also known as CIA (confidentiality, Integrity and Availability).
A typical DoS attack is where an attacker slows down, or disrupts completely services in our network. This damage can result from an arrack that destroys or crashes a system, or simply ﬂooding the network with so much data that it is incapable of servicing legitimate requests.
Information disclosure is considered more serious than data destruction because it is much less obvious and leaves the victim with a false sense of security, or a nagging dealing of insecurity like when Microsoft Windows source code was posted on the internet on February 2004.
One extremely obvious example of this happened during World War II. In 1942, the United States had accessed some of the Japanese naval codes. The Americans knew that the enemy was planning an assault on a location designated as “A.F”. The problem was they did not know what the destination A.F meant, though they suspected it designated Midway. So the American sent a message via underwater line to Midway asking them to transmit a message in the clear stating that their desalination facility used to produce fresh water was broken.
Shortly after the message was sent, the Japanese transmitted a new code message indicating that A.F was short on fresh water !The American was able then to position a ﬂeet to intercept the Japanese attack at Midway, leading to one of the most spectacular victories of World War II; a deﬁnitive turning point in the war in the Paciﬁc.
