Scenarios:
1. Shovels and Shingles is a small construction company consisting of 12 computers that have internet access. Discretionary Access Controls should be used in this scenario because the company is small and not in need of high security environment. This solution is the simplest to maintain and monitor for a small business.
2. Top Ads is a small advertising company consisting of 12 computers that have internet access. All employees communicate using smart phones. Mandatory Access Controls should be used in this scenario because the employees primarily communicate using smart phones, which opens up a security risk. Mandatory Access Controls are a step up stronger than Discretionary Access Controls, but are still relatively simple to monitor for a small business.
3. NetSecIT is a multinational IT services company consisting of 120,000 computers that have internet access and 45,000 servers. All employees communicate using smart phones and e-mail. Many employees work from home and travel extensively. Role Based Access Control should be used in this scenario because this is a large company with employees who travel and work from home. The roles should be controlled by a Security Administrator who could provide different levels of security to individual users. There would be some overhead in startup to get up and running but once in place this should be easy to manage.
4. Backordered Parts is a defense contractor that builds communication parts for the military. All employees communicate using smart phones and e-mail. Content-Dependent Access Controls should be used in this scenario since the company is manufacturing individual parts. Managing permissions based on the contents of each file is more time consuming and thus costly, but is also a lot more secure. This also allows the company to put less effort into monitoring data since each file is given its own
