تصميم نظام حاسوبي للحماية متعددة المستويات

الملخص

This research produces multilevel authentication used in sensitive
applications that contain sensitive levels of security and the maintain
confidential data. Proposed method divides the system to variety of levels
and tests users against different authentication methods for each level these
levels are further subdivided into more secure sublevels. Each of these
levels has its privileges and data that are managed by the administrator
called Identity Manager (IM) who has the full responsibility and authority to
decided transfer the user from one level to a higher level, or stay at the same
level. The decision of transition is done by allocate different weights for
each method achieved after a series of tests, the Director of identity must
issue a report describing the findings and resolution to the activity of all
users. This technique gives only the required privileges to selected users
who set their permissions to enter the system. The multi-level protection
methods include (password, multiple questions, cutting (Hash), RSA, and
DES) system was tested on a set of users, and has high security level.
