QUESTION 611 Joseph was the Web site administrator for the Mason Insurance in New York, who's main Web site was located at www.masonins.com. Joseph uses his laptop computer regularly to administer the Web site. One night, Joseph received an urgent phone call from his friend, Smith. According to Smith, the main Mason Insurance web site had been vandalized! All of its normal content was removed and replaced with an attacker's message ''Hacker Message: You are dead! Freaks! From his office, which was directly connected to Mason Insurance's internal network, Joseph surfed to the Web site using his laptop. In his browser, the Web site looked completely intact.

QUESTION 855 Basically, there are two approaches to network intrusion detection: signature detection, and anomaly detection. The signature detection approach utilizes well-known signatures for network traffic to identify potentially malicious traffic. The anomaly detection approach utilizes a previous history of network traffic to search for patterns that are abnormal, which would indicate an intrusion. How can an attacker disguise his buffer overflow attack signature such that there is a greater probability of his attack going undetected by the IDS? A. He can use a shellcode that will perform a reverse telnet back to his machine B. He can use a dynamic return address to overwrite the correct value in the target machine computer memory C. He can chain NOOP instructions into a NOOP "sled" that advances the processor's instruction pointer to a random place of choice D. He can use polymorphic shell code-with a tool such as ADMmutate - to change the signature of his exploit as seen by a network IDS
