That being said, there is no such thing as a computer that is 100% secure. In regards to the security of a network,…

the management of user access to databases and other network resources can become a daunting task. Users are dynamic, with changing privileges, and role based access controls (RBAC) are a powerful way to both organize permissions into groups, and therefore ease user administration.
