Q1. The GET method should never be used when sensitive data such as credit is being sent to a CGI program. This is because any GET command will appear in the URL and will be logged by any servers. For example, let’s say that you’ve entered your credit card information into a form that uses the GET method. The URL may appear like this:
https://www.xsecurity-bank.com/creditcard.asp?cardnumber=454543433532234
The GET method appends the credit card number to the URL. This means that anyone with access to a server log will be able to obtain this information.
How would you protect from this type of attack?
A. Replace the GET with POST method when sending data
B. Never include sensitive information in a script
C. Use HTTOS SSLV3 to send the data instead of plain HTTPS
D. Encrypt the data before you send using GET method
Answer: A
Explanation: If the method is "get", the user agent takes the value of action, appends a ? to it, then appends the form data set, encoded using the application/x-www-form-urlencoded content type. The user agent then traverses the link to this URI. If the method is "post" --, the user agent conducts an HTTP post transaction using the value of the action attribute and a message created according to the content type specified by the enctype attribute.
Q2. This kind of attack will let you assume a users identity at a dynamically generated web page or site:
A. SQL Injection
B. Cross Site Scripting
C. Session Hijacking
D. Zone Transfer
Answer: B
Explanation: Cross-site scripting (XSS) is a type of computer security vulnerability typically found in web applications which allow code injection by malicious web users into the web pages viewed by other users. Examples of such code include HTML code and client-side scripts. An exploited cross-site scripting vulnerability can be used by attackers to bypass access controls such as the same origin policy.
Q3. Angela is trying to access an education website that requires a username and password to login. When Angela clicks on the link to access the login page, she gets an error message stating that the page can’t be reached. She contacts the website’s support team and they report that no one else is having any issues with the site. After handing the issue over to her company’s IT department, it is found that the education website requires any computer accessing the site must be able to respond to a ping from the education’s server. Since Angela’s computer is behind a corporate firewall, her computer can’t ping the education website back.
What ca Angela’s IT department do to get access to the education website?
A. Change the IP on Angela’s Computer to an address outside the firewall
B. Change the settings on the firewall to allow all incoming traffic on port 80
C. Change the settings on the firewall all outbound traffic on port 80
D. Use a Internet browser other than the one that Angela is currently using
Answer: A
Explanation: Allowing traffic to and from port 80 will not help as this will be UDP or TCP traffic and ping uses ICMP. The browser used by the user will not make any difference. The only alternative here that would solve the problem is to move the computer to outside the firewall.
Q4. What is the goal of a Denial of Service Attack?
A. Capture files from a remote computer.
B. Render a network or computer incapable of providing normal service.
C. Exploit a weakness in the TCP stack.
D. Execute service at PS 1009.
Answer: B
Explanation: In computer security, a denial-of-service attack (DoS attack) is an attempt to make a computer resource unavailable to its intended users. Typically the targets are high-profile web servers, and the attack attempts to make the hosted web pages unavailable on the Internet. It is a computer crime that violates the Internet proper use policy as indicated by the Internet Architecture Board (IAB).
Q5. You are footprinting an organization to gather competitive intelligence. You visit the company’s website for contact information and telephone numbers but do not find it listed there. You know that they had the entire staff directory listed on their website 12 months ago but not it is not there.
How would it be possible for you to retrieve information from the website that is outdated?
A. Visit google’s search engine and view the cached copy.
B. Visit Archive.org web site to retrieve the Internet archive of the company’s website.
C. Crawl the entire website and store them into your computer.
D. Visit the company’s partners and customers website for this information.
Answer: B
Explanation:
Explanation: Archive.org mirrors websites and categorizes them by date and month depending on the crawl time. Archive.org dates back to 1996, Google is incorrect because the cache is only as recent as the latest crawl, the cache is over-written on each subsequent crawl. Download the website is incorrect because that's the same as what you see online. Visiting customer partners websites is just bogus. The answer is then Firmly, C, archive.org

Why will this not be possible?
A. Firewalls cannot inspect traffic coming through port 443
B. Firewalls can only inspect outbound traffic
C. Firewalls cannot inspect traffic at all, they can only block or allow certain ports
D. Firewalls cannot inspect traffic coming through port 80

Q9. When Nmap performs a ping sweep, which of the following sets of requests does it send to the target device?
A. ICMP ECHO_REQUEST & TCP SYN
B. ICMP ECHO_REQUEST & TCP ACK
C. ICMP ECHO_REPLY & TFP RST
D. ICMP ECHO_REPLY & TCP FIN
Answer: B
Explanation: The default behavior of NMAP is to do both an ICMP ping sweep (the usual kind of ping) and a TCP port 80 ACK ping sweep. If an admin is logging these this will be fairly characteristic of NMAP.
Q10. You are the Security Administrator of Xtrinity, Inc. You write security policies and conduct assesments to protect the company's network. During one of your periodic checks to see how well policy is being observed by the employees, you discover an employee has attached a modem to his telephone line and workstation. He has used this modem to dial in to his workstation, thereby bypassing your firewall. A security breach has occurred as a direct result of this activity. The employee explains that he used the modem because he had to download software for a department project. How would you resolve this situation?
A. Reconfigure the firewall
B. Conduct a needs analysis
C. Install a network-based IDS
D. Enforce the corporate security policy
Answer: D
Explanation: The security policy is meant to always be followed until changed. If a need rises to perform actions that might violate the security policy you’ll have to find another way to accomplish the task or wait until the policy has been changed.
