| 8.9.1 | Selection of a security model (user and share levels) as a good practice to ensure network security
There are two types of network security for protecting the network: share-level security and user-level security. Said to be weak and difficult to manage, share-level security allows users to access certain information if assigned a password by the network administrator. In order for an individual to access information on the network, he or she must provide a password, which is specifically assigned by a network administrator. User-level security specifies the rights and privileges of each user. The network administrator assigns the user an account to access a specific computer or network. When an individual attempts to log onto the network, the computer matches the user account id and password(s) against the security database before providing the user access.
