1. Walls, fences and gates: the oldest but most reliable methods of preventing unauthorized people from accessing resources. The NWU has two main gates upon entering the university. To enter the gate, you must have a student card. There are rolling doors in the computer facilities on the top floor where a student must swipe their student ID to gain access. NWU also has walls and fences around campus. This is extremely relevant in keeping unauthorized users out of the university and plays an important role in improving security.2. Guards: Unlike walls and fences which are static, guards can analyze different situations and act accordingly. At the main entrance to the university, there is always a guard at the door. If a student forgets their student ID, the guard can identify the individual and open the gate or not. However, this system can be improved - Sometimes guards open the gate too easily and sometimes guards don't always check the trunk of a car when exiting (there may be a stolen computer inside the trunk). This is relevant in order to ensure that unauthorized persons remain outside the university and that no resources are stolen, for example a computer. This definitely helps improve overall security.3. ID cards and badges: IDs are normally concealed when a badge has a name and photo on it. These can serve many purposes, but in the case of college, they serve as an access card. The university uses a badge type system and they are called student cards. Student cards have each student's first name, last name, and student number printed on the front of the card. The card also contains an RFID tag inside which acts as a key to enter the gates. They are very secure but can be......middle of paper......users away from the facilities. Few improvements can be made to the walls. Controls that are not in place may be considered1. Dogs: Guard dogs are sometimes used to protect valuable resources due to their keen sense of smell. For a university, dogs are probably not the best way to improve security. There are too many people moving around for a whole day. This may improve safety at night. Money spent on a guard dog is better spent elsewhere to improve security.2. Mantraps: can be defined as a small enclosure with separate input and output points. The university has somewhat of a man trap system with the rolling doors and the lobby, but not completely (because the entrance and exit are the same door). A mantrap system can be implemented easily with almost no effort, but don't think it will quite work for a university setup..
