This can mean providing access to necessary information to the appropriate personnel, while at the same time barring access to all others. For example, this capability would allow the systems administrator to set access to financial records or personnel files only for the personal computer in the chief executive's office. Access can also be barred to all other users or groups, keeping unauthorized personnel from gaining access to sensitive financial, company or personnel records. Process Software Corp.'s Purveyor IntraServer, for example, allows for the configuration of access control using the File Manager and clicking on files, directories or virtual paths. Users and groups can be managed within Purveyor's database, the Windows NT user registry database or even an external database like Microsoft Access.
Security can include encryption at several levels.
Most Web servers offer encryption for communications between the server and browser, effectively scrambling the message and keeping it from interception. Those employees who are entitled to view the information are equipped with software that reads the encrypted message and translates it into a readable format. Encryption and similar issues can be handled by the myriad software programs available on the market, including products from ABSystems Inc., Internet Security Systems , Solucom Inc. and the various other IT vendors that specialize in intranet security for business communication.
