Read the following scenario and then answer the question that follows.
Most of the users access the corporate database via a web server. The
default root directory of data repository web server is
C:\corporatedata\wwwroot.

Note is the following:
 Administrator users have access to this directory and all the other
subdirectories beneath this root;
 Team members have access to this directory and only to the
“faculty” and “admin” subdirectories beneath this root;
 Students only have access to the “student material” subdirectories
beneath this root.

After scanning the system, you suspect that malicious code has infected the
data repository files.

Explain the reason why it is difficult to handle the infection if the files were
infected through a rootkit.

Read the following scenario and draw a data flow logical diagram that includes both the context diagram and the ‘0’ level diagram (0 diagram) on a piece of paper, take a clear picture and upload it as the solution to this question.

ABC Video Shop plans to develop a video rental system. This system allows Video Shop employees to enter and store details of all videos / movies in the video file. The system enables members to enter required videos / movies and rent videos / movies, if available in store. All the videos / movie rental details will be stored in the rental file.

4.2 Read the following scenario and then answer the questions that follow:
You are the enterprise administrator in your organisation. You are
responsible for all systems including servers, clients, databases,
equipment, and mobile devices. Your ultimate goals are to ensure that the
network infrastructure is highly available and secured. You have been
alerted that a staff member, Employee A, has deleted and corrupted
numerous files on the system that would have contributed to providing
evidence in a scheduled disciplinary hearing against Employee A. The files
deleted have an impact on the business continuity, audit trails, and data
integrity.
The corrupted files have caused some of the systems to stop working. Your
goal is that you want to conduct a quantitative risk calculation focusing on
the likelihood of the risk.
Discuss any two quantitative tools that could help you achieve your goal.
