Executive management is asking for a new manufacturing control and workflow automation solution. This application will facilitate management of proprietary information and closely guarded corporate trade secrets.
The information security team has been a part of the department meetings and come away with the following notes:
Human resources would like complete access to employee data stored in the application. They would like automated data interchange with the employee management application, a cloud-based SaaS application.
Sales is asking for easy order tracking to facilitate feedback to customers.
Legal is asking for adequate safeguards to protect trade secrets. They are also concerned with data ownership questions and legal jurisdiction.
Manufacturing is asking for ease of use. Employees working the assembly line cannot be bothered with additional steps or overhead. System interaction needs to be quick and easy.
Quality assurance is concerned about managing the end product and tracking overall performance of the product being produced. They would like read-only access to the entire workflow process for monitoring and baselining.
The favored solution is a user friendly software application that would be hosted onsite. It has extensive ACL functionality, but also has readily available APIs for extensibility. It supports read-only access, kiosk automation, custom fields, and data encryption.
Which of the following departments’ request is in contrast to the favored solution?
Correct Answer:E
The human resources department wanted complete access to employee data stored in the application, and an automated data interchange with their cloud-based SaaS employee management application. However, the favored solution provides read-only access and is hosted onsite. Incorrect Answers:
A: The manufacturing department wanted a quick and easy user friendly system. The favored solution is a user friendly software application that would meet the manufacturing department’s requests.
B: The legal department wanted a system that provides adequate safeguards to protect trade secrets and was concerned with data ownership and legal jurisdiction. The favored solution is a user friendly software application that would be hosted onsite. This would address the legal department’s concerns with data ownership and legal jurisdiction. The application also provides data encryption, which would protect trade secrets.
C: The sales department wanted an easy order tracking to facilitate feedback to customers. The favored solution is a user friendly software application that supports custom fields, which could be used for order tracking.
D: The quality assurance department was concerned about managing the end product and tracking overall performance. They also wanted read-only access to the entire workflow process for monitoring and baselining. These are met by the favored solution.
A consultant is hired to perform a passive vulnerability assessment of a company to determine what information might be collected about the company and its employees. The assessment will be considered successful if the consultant can discover the name of one of the IT administrators. Which of the following is MOST likely to produce the needed information?
Correct Answer:A
Engineers at a company believe a certain type of data should be protected from competitors, but the data owner insists the information is not sensitive. An information security engineer is implementing controls to secure the corporate SAN. The controls require dividing data into four groups: nonsensitive, sensitive but accessible, sensitive but export-controlled, and extremely sensitive. Which of
the following actions should the engineer take regarding the data?
Correct Answer:C
An investigator wants to collect the most volatile data first in an incident to preserve the data that runs the highest risk of being lost. After memory, which of the following BEST represents the remaining order of volatility that the investigator should follow?
Correct Answer:C
The order in which you should collect evidence is referred to as the Order of volatility. Generally, evidence should be collected from the most volatile to the least volatile. The order of volatility from most volatile to least volatile is as follows:
Data in RAM, including CPU cache and recently used data and applications Data in RAM, including system and network processes
Swap files (also known as paging files) stored on local disk drives Data stored on local disk drives
Logs stored on remote systems Archive media
Incorrect Answers:
A: System and network processes are more volatile than file system information and swap files. B: System and network processes are more volatile than raw disk blocks.
D: System and network processes are more volatile than raw disk blocks and swap files. References:
