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.
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-DD-YYYY, (e.g. smartphone-12-25-2013.tmp) containing the price of the item being purchased. Which of the following is MOST likely being explogted to manipulate the price of a shopping cart’s items?

  • A. Input validation
  • B. SQL injection
  • D. Session hijacking

Answer: C

In this question, TOCTOU is being explogted to allow the user to modify the temp file that contains the price of the item.
In software development, time of check to time of use (TOCTOU) is a class of software bug caused by
changes in a system between the checking of a condition (such as a security credential) and the use of the results of that check. This is one example of a race condition.
A simple example is as follows: Consider a Web application that allows a user to edit pages, and also allows administrators to lock pages to prevent editing. A user requests to edit a page, getting a form which can be used to alter its content. Before the user submits the form, an administrator locks the page, which should prevent editing. However, since editing has already begun, when the user submits the form, those edits (which have already been made) are accepted. When the user began editing, the appropriate authorization was checked, and the user was indeed allowed to edit. However, the authorization was used later, at a time when edits should no longer have been allowed. TOCTOU race conditions are most common in Unix between operations on the file system, but can occur in other contexts, including local sockets and improper use of database transactions.
Incorrect Answers:
A: Input validation is used to ensure that the correct data is entered into a field. For example, input validation would prevent letters typed into a field that expects number from being accepted. The explogt in this question is not an example of input validation.
B: SQL injection is a type of security explogt in which the attacker adds Structured Query Language (SQL) code to a Web form input box to gain access to resources or make changes to dat
A. The explogt
in this question is not an example of a SQL injection attack.
D: Session hijacking, also known as TCP session hijacking, is a method of taking over a Web user session by obtaining the session ID and masquerading as the authorized user. The explogt in this question is not an example of session hijacking.

A company is in the process of implementing a new front end user interface for its customers, the goal is to provide them with more self-service functionality. The application has been written by developers over the last six months and the project is currently in the test phase.
Which of the following security activities should be implemented as part of the SDL in order to provide the MOST security coverage over the solution? (Select TWO).

  • A. Perform unit testing of the binary code
  • B. Perform code review over a sampling of the front end source code
  • C. Perform black box penetration testing over the solution
  • D. Perform grey box penetration testing over the solution
  • E. Perform static code review over the front end source code

Answer: DE

With grey box penetration testing it means that you have limited insight into the devise which would most probable by some code knowledge and this type of testing over the solution would provide the most security coverage under the circumstances.
A Code review refers to the examination of an application (the new network based software product in this case) that is designed to identify and assess threats to the organization. With a static code review it is assumed that you have all the sources available for the application that is being examined. By performing a static code review over the front end source code you can provide adequate security coverage over the solution.
Incorrect Answers:
A: Unit testing of the binary code will not provide the most security coverage.
B: Code review over a sampling of the front end source code will not provide adequate security coverage.
C: Black box penetration testing is best done when the source code is not available. References:

A security manager is looking into the following vendor proposal for a cloud-based SIEM solution. The intention is that the cost of the SIEM solution will be justified by having reduced the number of incidents and therefore saving on the amount spent investigating incidents.
External cloud-based software as a service subscription costing $5,000 per month. Expected to reduce the number of current incidents per annum by 50%.
The company currently has ten security incidents per annum at an average cost of $10,000 per incident. Which of the following is the ROI for this proposal after three years?

  • A. -$30,000
  • B. $120,000
  • C. $150,000
  • D. $180,000

Answer: A

Return on investment = Net profit / Investment where: Net profit = gross profit - expenses.
Return on investment = (gain from investment – cost of investment) / cost of investment Subscriptions = 5,000 x 12 = 60,000 per annum
10 incidents @ 10,000 = 100.000 per annum reduce by 50% = 50,000 per annum
Thus the rate of Return is -10,000 per annum and that makes for -$30,000 after three years. References:

Which of the following represents important technical controls for securing a SAN storage infrastructure? (Select TWO).

  • A. Synchronous copy of data
  • B. RAID configuration
  • C. Data de-duplication
  • D. Storage pool space allocation
  • E. Port scanning
  • F. LUN masking/mapping
  • G. Port mapping

Answer: FG

A logical unit number (LUN) is a unique identifier that designates individual hard disk devices or
grouped devices for address by a protocol associated with a SCSI, iSCSI, Fibre Channel (FC) or similar interface. LUNs are central to the management of block storage arrays shared over a storage area network (SAN).
LUN masking subdivides access to a given port. Then, even if several LUNs are accessed through the same port, the server masks can be set to limit each server's access to the appropriate LUNs. LUN masking is typically conducted at the host bus adapter (HBA) or switch level.
Port mapping is used in ‘Zoning’. In storage networking, Fibre Channel zoning is the partitioning of a Fibre Channel fabric into smaller subsets to restrict interference, add security, and to simplify management. While a SAN makes available several devices and/or ports to a single device, each system connected to the SAN should only be allowed access to a controlled subset of these devices/ports.
Zoning can be applied to either the switch port a device is connected to OR the WWN World Wide Name on the host being connected. As port based zoning restricts traffic flow based on the specific switch port a device is connected to, if the device is moved, it will lose access. Furthermore, if a different device is connected to the port in question, it will gain access to any resources the previous host had access to.
Incorrect Answers:
A: Synchronous copy of data is used to copy data. It is not a technical control for securing a SAN storage infrastructure.
B: RAID configuration is the configuration of the disks in the SAN. A RAID is an array of disks that provides a logical pool of storage by combining the storage capacity of the disks. RAID provides hardware redundancy in that the data will not be lost if an individual disk fails. RAID configuration is not a technical control for securing a SAN storage infrastructure.
C: Data de-duplication is the process of eliminating multiple copies of the same data to save storage space. It is not a technical control for securing a SAN storage infrastructure.
D: Storage pool space allocation is the process of allocating and making available portions of the storage pool to servers. It is not a technical control for securing a SAN storage infrastructure.
E: Port scanning is the process of probing a server or host for open ports. It is not a technical control for securing a SAN storage infrastructure.
