System access control covers all the methods that serve to protect a DP system against unauthorized access.
BS2000 OSD/BC
System access control using a LOGON password in the SET-LOGON-PARAMETERS command is currently the most widespread authentication procedure. The MODIFY-USER-PROTECTION command is used to declare an 8- or 32-byte password for the user ID.
With the help of organizational functions provided by SECOS, password protection in BS2000 can be substantially improved. To this end, user administration defines explicitly for each user which of the following stipulations that user must observe:
minimum length of a password
complexity of a password
lifetime of a password.
Extended system access control with SECOS
SECOS offers the following additional options for system access control:
Separation of access paths
Access restrictions via terminal sets
Guards access protection
Personal identification
Logging access attempts
