Data encryption protects your projects and your production data from unauthorised access, both in transit and at rest. eScada implements it through multiple layers of protection:
- All communication channels between the server and clients are encrypted with keys derived from passphrases defined in the project, ensuring secure data transmission across the network.
- All runtime files generated for alarm management, trends, and recipes can be optionally encrypted with individual keys derived from passphrases defined in the project, providing granular control over sensitive operational data.
- Project files themselves are encrypted to create a secure vault for all configuration data, design specifications, and system parameters, ensuring that only authorised individuals can access the core project contents.
All keys are derived from passphrases defined in the project: you decide what to protect, and with which secrets.
