How do you defend against Privilege Escalation?

Anonymizer sites access the Internet on your behalf, protecting your personal information from disclosure. An anonymizer protects all of your computer’s identifying information while it surfs for you, enabling you to remain at least one step removed from the sites you visit.

You can visit Web sites without allowing anyone to gather information on sites visited by you. Services that provide anonymity disable pop-up windows and cookies, and conceal visitor’s IP address.

These services typically use a proxy server to process each HTTP request. When the user requests a Web page by clicking a hyperlink or typing a URL into their browser, the service retrieves and displays the information using its own server. The remote server (where the requested Web page resides) receives information on the anonymous Web surfing service in place of your information.

Lyle is a systems security analyst for Gusteffson & Sons, a large law firm in Beverly Hills. Lyle’s responsibilities include network vulnerability scans, Antivirus monitoring, and IDS monitoring. Lyle receives a help desk call from a user in the Accounting department. This user reports that his computer is running very slow all day long and it sometimes gives him an error message that the hard drive is almost full. Lyle runs a scan on the computer with the company antivirus software and finds nothing. Lyle downloads another free antivirus application and scans the computer again. This time a virus is found on the computer. The infected files appear to be Microsoft Office files since they are in the same directory as that software. Lyle does some research and finds that this virus disguises itself as a genuine application on a computer to hide from antivirus software.
What type of virus has Lyle found on this computer?

Steven is the senior network administrator for Onkton Incorporated, an oil well drilling company in Oklahoma City. Steven and his team of IT technicians are in charge of keeping inventory for the entire company; including computers, software, and oil well equipment. To keep track of everything, Steven has decided to use RFID tags on their entire inventory so they can be scanned with either a wireless scanner or a handheld scanner. These RFID tags hold as much information as possible about the equipment they are attached to. When Steven purchased these tags, he made sure they were as state of the art as possible. One feature he really liked was the ability to disable RFID tags if necessary. This comes in very handy when the company actually sells oil drilling equipment to other companies. All Steven has to do is disable the RFID tag on the sold equipment and it cannot give up any information that was previously stored on it.

What technology allows Steven to disable the RFID tags once they are no longer needed?

When a malicious hacker identifies a target and wants to eventually compromise this target, what would be the first step the attacker would perform?

Reflective DDoS attacks do not send traffic directly at the targeted host. Instead, they usually spoof the originating IP addresses and send the requests at the reflectors. These reflectors (usually routers or high-powered servers with a large amount of network resources at their disposal) then reply to the spoofed targeted traffic by sending loads and loads of data to the final target.

How would you detect these reflectors on your network?

TCP/IP Session Hijacking is carried out in which OSI layer?

Leonard is a systems administrator who has been tasked by his supervisor to slow down or lessen the amount of SPAM their company receives on a regular basis. SPAM being sent to company email addresses has become a large problem within the last year for them. Leonard starts by adding SPAM prevention software at the perimeter of the network. He then builds a black list, white list, turns on MX callbacks, and uses heuristics to stop the incoming SPAM. While these techniques help some, they do not prevent much of the SPAM from coming in. Leonard decides to use a technique where his mail server responds very slowly to outside connected mail servers by using multi-line SMTP responses. By responding slowly to SMTP connections, he hopes that SPAMMERS will see this and move on to easier and faster targets.

What technique is Leonard trying to employ here to stop SPAM?
