Sensitive data

Security-relevant and sensitive data can be protected through appropriate measures such as
passwords and protection functions.
For certain data, protection is already essential and implemented within the system (e.g.
certificate management in the TIA Portal).
Sensitive data
Confidential configuration data (private keys,
passwords/access data)
User management data
Configuration of CPUs and interface modules Protection through
Blocks (data blocks, logic blocks)
Data deemed sensitive by the operator

Backups and data backups

Regular backups or data backups after successful installation should be part of a successful
security concept. Whether for restoring a project if required, if the changes made do not yield
the desired results, or for saving an installation in an emergency.
Options for backing up a STEP 7 project:
• Project backup via online backup, see article Online backup
(https://support.industry.siemens.com/cs/us/en/view/109759862/91508694411)
• Project backup via the TIA Portal, see article What options are there in STEP 7 (TIA Portal)
for backing up projects and what is the significance of the backup files of the projects?

You can find more information in the section Backing up and restoring the CPU configuration
(Page 284).

Additional measures for network security

The following measures additionally increase the protection against unauthorized access to
functions and data of the CPU from external sources and via the network: You can find
information on these topics in the section Other CPU protective measures in Overview of the
protective functions (Page 236).
You can find information on network security and network components for protection from
unauthorized access in the PROFINET Function Manual
