4.7.7 Data backup
Secure your configuration and parameter settings so that you can quickly restore this data if
needed.
4.7.8 Security checks
Security checks for data, files, and archives serve to ensure data integrity at the storage
location and during file transmission, protecting against manipulation and transmission
errors. This is often achieved using digital checksums that are provided alongside the data.
Tools (such as SHA-256 or SHA-512) for calculating and verifying these checksums are
provided in many systems and named according to their respective calculation methods.
• File Integrity Guidelines describe the prescribed procedure for integrity checks
• Integrity protection is a protection function for engineering data and firmware files
• Communication integrity means protecting communication against unauthorized
manipulations to ensure high system availability. A central element in this regard is, for
example, the use of digital checksums when accessing controllers. (Source: Industrial
