Security Levels

Networks require a special standard of security because there is so much data stored in places where many users can access it without proper security measures. These measures include grouping users according to their access requirements, and allocating the proper access rights to these groups or individual users.

All network operating systems allow administrators to block or grant access to certain sections of the network servers. Granted access can also be modified from read only to modify or to full access, which allows the deletion and renaming of files.

An example of this could be in stock control. An organisation may wish to allow all employees, especially customer service, marketing and accounting employees to view the amount of stock in the stock database, but only the warehouse staff should have the rights to change stock levels.
