Role separation provides checks and balances to improve the security of your event-auditing procedures. Event auditing tracks selected activities that users perform. With role separation enabled, members of different groups manage and examine these records to ensure additional security.
You must set up two roles to enable role separation:
For audit purposes, you should establish one account for each individual who acts as a DBSSO or AAO. For example, DBSSO1 and DBSSO2 might be the account names for the DBSSO role and bertAAO and harryAAO might be the account names for the AAO role. In addition, all standard users should have separate account names.
By default, all user groups can access the database server. To access the database server, standard users must belong to one of the user groups. To restrict standard-user access to the database, create a special group. If you specify that group during the role-separation portion of database server installation, only members of that special group can access the database server.
Do not use informix or root for the DBSSO and AAO account names.
