Q345. Which of the following buffer overflow exploits are related to Microsoft IIS web server? (Choose three)
A. Internet Printing Protocol (IPP) buffer overflow
B. Code Red Worm
C. Indexing services ISAPI extension buffer overflow
D. NeXT buffer overflow
Explanation: Both the buffer overflow in the Internet Printing Protocol and the ISAPI extension buffer overflow is explained in Microsoft Security Bulletin MS01-023. The Code Red worm was a computer worm released on the Internet on July 13, 2001. It attacked computers running Microsoft's IIS web server.
Q346. The FIN flag is set and sent from host A to host B when host A has no more data to transmit (Closing a TCP connection). This flag releases the connection resources. However, host A can continue to receive data as long as the SYN sequence number of transmitted packets from host B are lower than the packet segment containing the set FIN flag.
Explanation: For sequence number purposes, the SYN is considered to occur before the first actual data octet of the segment in which it occurs, while the FIN is considered to occur after the last actual data octet in a segment in which it occurs. So packets receiving out of order will still be accepted.
Q347. What is a sniffing performed on a switched network called?
A. Spoofed sniffing
B. Passive sniffing
C. Direct sniffing
D. Active sniffing
Q348. What makes web application vulnerabilities so aggravating? (Choose two)
A. They can be launched through an authorized port.
B. A firewall will not stop them.
C. They exist only on the Linux platform.
D. They are detectable by most leading antivirus software.
Explanation: As the vulnerabilities exists on a web server, incoming traffic on port 80 will probably be allowed and no firewall rules will stop the attack.
Q349. Gerald is a Certified Ethical Hacker working for a large financial institution in Oklahoma City. Gerald is currently performing an annual security audit of the company's network. One of the company's primary concerns is how the corporate data is transferred back and forth from the banks all over the city to the data warehouse at the company's home office. To see what type of traffic is being passed back and forth and to see how secure that data really is, Gerald uses a session hijacking tool to intercept traffic between a server and a client. Gerald hijacks an HTML session between a client running a web application which connects to a SQL database at the home office. Gerald does not kill the client's session; he simply monitors the traffic that passes between it and the server.
What type of session attack is Gerald employing here?
A. He is utilizing a passive network level hijack to see the session traffic used to communicate between the two devices
B. Gerald is using a passive application level hijack to monitor the client and server traffic
C. This type of attack would be considered an active application attack since he is actively monitoring the traffic
D. This type of hijacking attack is called an active network attack
Explanation: Session Hijacking is an active attack
Q350. What are the three phases involved in security testing?
A. Reconnaissance, Conduct, Report
B. Reconnaissance, Scanning, Conclusion
C. Preparation, Conduct, Conclusion
D. Preparation, Conduct, Billing
Explanation: Preparation phase - A formal contract is executed containing non-disclosure of the client's data and legal protection for the tester. At a minimum, it also lists the IP addresses to be tested and time to test. Conduct phase - In this phase the penetration test is executed, with the tester looking for potential vulnerabilities. Conclusion phase - The results of the evaluation are communicated to the pre-defined organizational contact, and corrective action is advised.
