Recommendation
We recommend that you regularly review the following criteria for protecting the standard users:
Maintain an overview of the clients that you have and make sure that no unknown clients exist.
Make sure that SAP* exists and has been deactivated in all clients.
Make sure that the default passwords for SAP*, DDIC, and EARLYWATCH have been changed.
Make sure that these users belong to the group SUPER in all clients.
Lock the users SAP*, DDIC, and EARLYWATCH. Unlock them only when necessary. It should never be necessary to use SAP*!
Do not delete EARLYWATCH. This user should only be used for Early Watch functions (monitoring and performance).
To find out which clients you have in your system, display the table T000 using transaction SM30.
To make sure that the user SAP* has been created in all clients and that the standard passwords have been changed for SAP*, DDIC and EARLYWATCH, use the report RSUSR003.
