Residual Data Removal

Remove residual data, which strengthens the security of database data.

Some database operations that delete space do not always physically erase the data. This can pose a security threat, as this residual data may be visible to a user using the dbcc utility. To prevent this, SAP ASE version 16.0 introduces a feature that zeroes out residual data without additional work when the user performs these database operations.

You can mark data as sensitive, and configure SAP ASE to erase its residual data after performing delete or update operations.
