QUESTION TWO [30] A friend of yours, John Doe, has recently applied for a position with a medium sized manufacturing concern. Although the position is in the accounting department the advertisement indicated that candidates should have certain computer skills e.g. compiling spreadsheets, using AccSoft accounting software etc, and have an appreciation of the importance of matters such as access controls in a computer environment. John Doe has a Bcom from Regent Business School and whilst working and studying has picked up the necessary skills required by the company. He has been short listed for the position and has been called for an interview. However, he is concerned about one of the paragraphs in the letter he received inviting him for an interview. "In addition to having the computer skills described in the advertisement (and which you appear to have) candidates are expected to have an understanding of access controls in computerized environment. Expert knowledge is not required but candidates must be able to display their understanding in the interview if required to so." John Doe's reaction has been to approach you for help. "I have an understanding of access controls that affect me in my day to day living, like keeping my PIN number safe, but could you run through access controls in a working environment and just remind me on password controls." You agreed to assist. Required 2.1. Provide John Doe with a basic understanding of access control in a computerized environment. 2.2. List the common password controls. (20)
