Jeffery works at a large financial firm in Dallas, Texas as a securities analyst. Last week, the IT department of his company installed a wireless network throughout the building. The problem is, is that they are only going to make it available to upper management and the IT department.

Most employees don’t have a problem with this since they have no need for wireless networking, but Jeffery would really like to use wireless since he has a personal laptop that he works from as much as he can. Jeffery asks the IT manager if he could be allowed to use the wireless network but he is turned down. Jeffery is not satisfied, so he brings his laptop in to work late one night and tries to get access to the network. Jeffery uses the wireless utility on his laptop, but cannot see any wireless networks available. After about an hour of trying to figure it out, Jeffery cannot get on the company’s wireless network. Discouraged, Jeffery leaves the office and goes home.

The next day, Jeffery calls his friend who works with computers. His friend suggests that his IT department might have turned off SSID broadcasting, and that is why he could not see any wireless networks. How would Jeffrey access the wireless network?

Jason works in the sales and marketing department for a very large advertising agency located in Atlanta. Jason is working on a very important marketing campaign for his company’s largest client. Before the project could be completed and implemented, a competing advertising company comes out with the exact same marketing materials and advertising, thus rendering all the work done for Jason’s client unusable. Jason is questioned about this and says he has no idea how all the material ended up in the hands of a competitor.

Without any proof, Jason’s company cannot do anything except move on. After working on another high profile client for about a month, all the marketing and sales material again ends up in the hands of another competitor and is released to the public before Jason’s company can finish the project. Once again, Jason says that he had nothing to do with it and does not know how this could have happened. Jason is given leave with pay until they can figure out what is going on.

Jason’s supervisor decides to go through his email and finds a number of emails that were sent to the competitors that ended up with the marketing material. The only items in the emails were attached jpg files, but nothing else. Jason’s supervisor opens the picture files, but cannot find anything out of the ordinary with them.

What technique has Jason most likely used?

More sophisticated IDSs look for common shellcode signatures. But even these systems can be bypassed, by using polymorphic shellcode. This is a technique common among virus writers – it basically hides the true nature of the shellcode in different disguises.

James is an IT security consultant as well as a certified ethical hacker. James has been asked to audit the network security of Yerta Manufacturing, a tool manufacturing company in Phoenix. James performs some initial external tests and then begins testing the security from inside the company’s network.

James finds some big problems right away; a number of users that are working on Windows XP computers have saved their usernames and passwords used to connect to servers on the network. This way, those users do not have to type in their credentials every time they want access to a server. James tells the IT manager of Yerta Manufacturing about this, and the manager does not believe this is possible on Windows XP. To prove his point, James has a user logon to a computer and then James types in a command that brings up a window that says "Stored User Names and Passwords".

What command did James type in to get this window to come up?

Charlie is an IT security consultant that owns his own business in Denver. Charlie has recently been hired by Fleishman Robotics, a mechanical engineering company also in Denver. After signing service level agreements and other contract papers, Charlie asks to look over the current company security policies. Based on these policies, Charlie compares the policies against what is actually in place to secure the company’s network. From this information, Charlie is able to produce a report to give to company executives showing which areas the company is lacking in. This report then becomes the basis for all of Charlie’s remaining tests.

What type of initial analysis has Charlie performed to show the company which areas it needs improvements in?

An SNMP scanner is a program that sends SNMP requests to multiple IP addresses, trying different community strings and waiting for a reply. Unfortunately SNMP servers don’t respond to requests with invalid community strings and the underlying protocol does not reliably report closed ports. This means that ‘no response’ from the probed IP address can mean which of the following:
