Hackers are not only clever in how they invade servers; they are also devious in how they disguise their attacks. Malicious attackers use a variety of evasive techniques, which we will examine in this column so that we, as administrators, can be better prepared to detect and respond to them.
In our last column, we discussed some of the most common types of attacks against Web servers, and the evidence they leave in Web server logs. In this column, rather than initiating new attacks, we will demonstrate some dirty tricks hackers use to avoid detection, and the evidence they leave behind. These techniques are an added twist to the attacks we examined last time, making those attacks more difficult to detect.
