Paul has just finished setting up his wireless network. He has enabled numerous security features such as changing the default SSID, enabling WPA encryption, and enabling MAC filtering on his wireless router. Paul notices that when he uses his wireless connection, the speed is sometimes 54 Mbps and sometimes it is only 24Mbps or less. Paul connects to his wireless router's management utility and notices that a machine with an unfamiliar name is connected through his wireless connection. Paul checks the router's logs and notices that the unfamiliar machine has the same MAC address as his laptop. What is Paul seeing here?

A specific site received 91 ICMP_ECHO packets within 90 minutes from 47 different sites. 77 of the ICMP_ECHO packets had an ICMP ID:39612 and Seq:57072. 13 of the ICMP_ECHO packets had an ICMP ID:0 and Seq:0. What can you infer from this information?
John has scanned the web server with NMAP. However, he could not gather enough information to help him identify the operating system running on the remote host accurately.
What would you suggest to John to help identify the OS that is being used on the remote web server?
What are the two basic types of attacks? (Choose two.
Harold is the senior security analyst for a small state agency in New York. He has no other security professionals that work under him, so he has to do all the security-related tasks for the agency. Coming from a computer hardware background, Harold does not have a lot of experience with security methodologies and technologies, but he was the only one who applied for the position. Harold is currently trying to run a Sniffer on the agency's network to get an idea of what kind of traffic is being passed around, but the program he is using does not seem to be capturing anything. He pours through the Sniffer's manual, but cannot find anything that directly relates to his problem. Harold decides to ask the network administrator if he has any thoughts on the problem. Harold is told that the Sniffer was not working because the agency's network is a switched network, which cannot be sniffed by some programs without some tweaking. What technique could Harold use to sniff his agency's switched network?
Which of the following ICMP message types are used for destinations unreachables?
You are manually conducting Idle Scanning using Hping2. During your scanning you notice that almost every query increments the IPID regardless of the port being queried. One or two of the queries cause the IPID to increment by more than one value. Why do you think this occurs?
Which Windows system tool checks integrity of critical files that has been digitally signed by Microsoft?
Which of the following would be the best reason for sending a single SMTP message to an address that does not exist within the target company?
What port scanning method involves sending spoofed packets to a target system and then looking for adjustments to the IPID on a zombie system?
What is the disadvantage of an automated vulnerability assessment tool?
A XYZ security System Administrator is reviewing the network system log files.
He notes the following:
Network log files are at 5 MB at 12:00 noon.
At 14:00 hours, the log files at 3 MB.
What should he assume has happened and what should he do about the situation?
While attempting to discover the remote operating system on the target computer, you receive the following results from an nmap scan:
Remote operating system guess: Too many signatures match to reliably guess the OS.
Nmap run completed -- 1 IP address (1 host up) scanned in 277.483 seconds
What should be your next step to identify the OS?
While footprinting a network, what port/service should you look for to attempt a zone transfer?
What does an ICMP (Code 13) message normally indicates?
Sandra has been actively scanning the client network on which she is doing a vulnerability assessment test. While conducting a port scan she notices open ports in the range of 135 to 139. What protocol is most likely to be listening on those ports?
A very useful resource for passively gathering information about a target company is:
The following excerpt is taken from a honeyput log. The log captures activities across three days. There are several intrusion attempts; however, a few are successful. Study the log given below and answer the following question:
(Note: The objective of this questions is to test whether the student has learnt about passive OS fingerprinting (which should tell them the OS from log captures): can they tell a SQL injection attack signature; can they infer if a user ID has been created by an attacker and whether they can read plain source – destination entries from log entries.)
What can you infer from the above log?
