Ensuring secure administration

Configuration validation is a tool that allows systems to be tested against corporate or organisational requirements and regulations. You can find this tool in the Change Management section of the SAP Solution Manager. This allows you to evaluate security-relevant configurations and critical permissions. This is based on the SAP Solution Manager's Configuration and Change Database (CCDB), which stores all details about the configuration of the connected systems. The configuration data is stored in different configuration stores, depending on the type of configuration. You can evaluate the configuration of the operating system, the database, and profile parameters in the ABAP and Java systems. You will also get an overview of the status of transport orders and support packages. You can also track changes to the configurations of the attached systems in the CCDB. You can also graphically evaluate these changes via an end-to-end analysis in SAP BW; contains information on the number of changes per system, the type of changes and the modification date.
If you use configuration validation, we still recommend that you use the AGS Security Services, such as the EarlyWatch Alerts and SAP Security Optimisation Services, which we describe in Tip 93, "AGS Security Services." SAP keeps the specifications and recommendations in the AGS Security Services up to date and adapts them to new attack methods and security specifications. If you have identified new security issues within a security service, you can set your target systems accordingly and monitor these aspects in the future.

In the SAP system, passwords are locked when the maximum number of allowed password login errors is reached. This counter is reset with a password each time you successfully log in. In addition, an initial password can be locked when its validity has expired. Both the validity of the initial password and the maximum value for password login errors are set using profile parameters. For details, see Tip 4, "Set password parameters and valid passwords characters". A password lock only prevents a user from logging in via his password, because the number of errors is only evaluated if the login is done by password. If a login is now made via other authentication methods (such as SSO), these are not affected by the password lock. This also applies to internal expiration procedures (such as background jobs) because you do not need to register a password. This prevents, for example, denial-of-service attacks, which first cause a password to be locked in order to block internal processes. Eine Ausnahme von dieser Regel gibt es allerdings: Auch wenn andere Authentifizierungsverfahren genutzt werden, prüft das System, ob der Benutzer dazu in der Lage ist, sich mit einem Passwort anzumelden. Wenn dies der Fall ist und das Passwort gerade geändert werden muss, wird diese Änderung vom Benutzer abgefragt. Diese Abfrage können Sie aber auch mithilfe des Profilparameters login/password_change_for_SSO ausschalten.
If you want to cancel, share, or reset other users' jobs to scheduled status, you must have permission for the S_BTCH_ADM object with a value of Y. Alternatively, you can also grant the JOBACTION = MODI and JOBGROUP = permission for the S_BTCH_JOB object. The MODI promotion was introduced with SAP NetWeaver AS ABAP 7.00 or can be recorded via SAP Note 1623250. The following illustration shows an example of how the JOBACTION = MODI privilege is expressed for the jobs of the users listed under JOBGROUP.
With "Shortcut for SAP systems" you can automate the assignment of roles after a go-live.

Running the system trace for permissions gradually for each application server is tedious.
So much information... how can you keep it so that you can find it again when you need it? Scribble Papers is a "note box" that makes this very easy.
If you set both switches to YES, you will not be able to tell from the user menu entries whether they are from the reference user's or user's role menus.
