User Access Levels

User Access Levels
One technique to improve the security of a network is using user access levels.
Access rights
- Users of a computer system can be given different access rights for different files on the system.
- For example, for each file on the system we might keep a record of whether each user can:
- Read the file.
- Write to the file.
- Execute the file.
User access levels
- Network users can be arranged into user groups.
- Each group can then be given different access rights.
- This makes it easy to manage the access rights of a large group of people (e.g. employees).
Advantages of user access levels
- We can limit the access rights of 'normal' users on the network. For example:
- Not allowing them to install software.
- Not allowing them to create new user accounts.
- Not allowing them access to confidential information.
- These rights can be limited to the administrators only.
