Security

InFoCAD provides several levels of security, the degree of which is controlled by the InFoCAD system manager. InFoCAD can function in a completely open or in a completely secure environment.

Access to InFoCAD itself is controlled by a complex user profile. Permissions at the file level are further controlled by read/write permissions. InFoCAD also comes equipped with a data dictionary. All these security features are independent of and in addition to UNIX or Windows NT security.

InFoCAD Profile

By means of the InFoCAD profile, the system manager assigns each user a user name and password, a User Identification Code (UIC), permission to access CADD, GIS, and DB commands, access to database views, and permission to each of the 999 layers.

The UIC is a two-digit number, for example [2,1], which indicates the group and owner numbers, respectively. Users with InFoCAD may have the same UIC because they are distinguished by their user names. The UIC of the user is stamped in any file created.

Furthermore, each command in InFoCAD is defined as one of three types: CADD, GIS, DB. The System Manager may bar certain users from any of the CADD, GIS and/or DB commands. Regardless of the file-levl permission, user who do not CADD permission, cannot draw or delete graphic objects.

The profile defines to which of 16 database views the particular user has permission. For example, certain users may not be able to access the first five views of a sensitive database. This feature allows users with different levels of security clearance to access the same database while ensuring data security.

This same concept is applied to InFoCAD’s 999 layers. Certain users maybe defined as unable to view certain layers, for example the middle 50 in all drawings. The classified information may then be placed on these layers and only privileged users may view it.

Permissions at File Level

As users create Libraries or databases, their UIC is stamped in it as the OWNER UIC. Additionally, users must assign read and write permissions to the GROUP, WORLD, and OWNER. The owner could conceivably bar him or herself from editing or even viewing the file. Subsequently, each Library and/or database within InFoCAD can be accessed and modified only those users with appropriate UIC numbers and read/write permission.

Data Dictionary

InFoCAD features a data dictionary, which serves as a repository for all database standard definition files (SDF). This means a user must have an InFoCAD user name and password, and the correct file permission to access information about and in the databases.In addition, the databases can be encrypted so that even if access is gained, the information cannot be deciphered.

These enhanced security features, coupled with UNIX or Windows NT security, ensure a completely secure environment when desired.
