ABAP systems Protection against password hash attacks, SAP security note 1237762

Description

You want to protect an ABAP system against password hash attacks.
In an attack of this type, the hash value of a password is calculated outside the SAP kernel and then compared to the hash value that is stored in the database of the SAP system.

Unlike other attacks, password hash attacks cannot be prevented by limiting the permitted number of failed password logon attempts (profile parameter login/fails_to_user_lock).
