110791 SECUR: A DIBOL Subroutine Developed to Provide an Extra Level of Security Version: V1.6, December 1984 Submitted by: H. Pettigrew, Burrellco Inc., Kennesaw, GA Operating System: RT-11 V4.0, TSX-PLUS V5.0 Source Language: DIBOL Software Required: DIBOL Compiler Hardware Required: VT100 or emulator Keywords: DIBOL, System Management - RT-11 Abstract: SECUR is a DIBOL subroutine callable from any DIBOL program. It was developed to provide an extra level of security in certain of our highly sensitive applications. The subroutine makes extensive use of DIBOL's internally callable features to make it virtually impossible for anyone to discover the name of the password file or module name. Provisions have been made to allow the entry and updating of passwords, using oldpassword frontslash newpassword. An optional feature is the ability to save all unsuccessful attempts, with the date, time, password used and terminal line number. It is assumed the user is sophisticated enough to establish the required disc files using KED, and can compile the source module and modify any application program needing additional security. The subroutine is extremely well documented within the source code module and can be modified by the end user to meet any changing need. Restrictions: Must be called as a subroutine.
