Cybersecurity protection and recovery

MDT AutoSave addresses a critical aspect of security not addressed by data access & network monitoring applications: The Intellectual Property in your Device Programs
Cybersecurity protection and recovery
Prepare for a cybersecurity attack
  • Secure your program intellectual property: AutoSave saves a copy of each program revision in a central repository. Access to program and program folders, is managed via a flexible privileging system.
Detect a cyber security breach
  • Detect changes made outside the change management system: AutoSave compares the latest program copy on file in AutoSave with the program running in each device to identify any differences. If differences are found, the appropriate people are notified with an email highlighting the differences.
Recover from a cybersecurity attack
  • Rapidly recover from unauthorized changes: With an archive of all program revisions, you can quickly restore the latest approved program after an unauthorized change.

Rapid disaster recovery

The key to rapid recovery is the ability to access and download the correct automation program to the device. A common central repository of all program changes ensures that if a device fails, the most current copies of program logic and documentation are available so plant operations can be restored quickly and correctly.
Rapid disaster recovery
Central database of program backups
  • Users can remove an incorrect device program change and roll back to any previous version within seconds.
Historical tracking
  • It is of significant use when assessing areas for process improvement to be able to identify the frequency and type of changes to each device against its device type, production line and those individuals making the changes. When norms are identified it is straightforward to identify devices that are experiencing excessive changes and aid in identifying root causes.

Program comparison and notification

AutoSave can interrogate devices and compare the program running in the device to a reference copy in AutoSave. If changes are detected, appropriate identification and notification will occur.
Identify unknown or unauthorized changes
  • AutoSave periodically queries your automation devices and compares the code running in the processor with the latest version stored on the AutoSave Server. If a mismatch is detected (indicating someone went around our system to make a change), a notification is sent to key personnel highlighting the mismatch along with information pinpointing the changes, thus protecting your process, people and equipment.

Non-networked device management

AutoSave supports non-networked devices by allowing you to make changes to programs in the field then analyze and sync all changes to the server back at the office.

• View a history of changes performed on each device
• Undo changes in the field with a simple button push
• Compare the program running in the device to the program on the engineer’s laptop
• Copy programs to create new programs in the field

User access and security control

MDT AutoSave manages access to program folders and programs via a flexible privileging system, enabling changes in program logic to be recorded by user, date, time, location and specific change detail.

Electronic signature and workflow approval

As regulatory bodies require more ability to trace process changes and ensure compliance with current regulations (i.e. 21CFR11), manufacturers are seeking ways to be assured the process has not been altered without approval. No other Automation Change Management system claims to be compliant with 21CFR11. MDT AutoSave is.
Audit Trail & Approval
  • AutoSave tracks changes in PLCs, human-machine interface systems and workstations to ensure a proper audit trail and notification of changes. This can be invaluable in understanding what changes were made, why, and by whom.
Electronic Signature and Workflow Approval
  • To further increase the level of change control, AutoSave provides workflow approval routing and electronic signature functionality in support of 21CFR11 guidelines. For areas requiring even greater electronic approval and audit trail support, AutoSave’s Add-On Modules provide this functionality.

Tracking Firmware versions in automation devices

AutoSave can track data such as firmware, software and CPU versions in automation devices from the following vendors: Siemens, Schneider, Mitsubishi and Rockwell (support for additional device types and automation vendors will be added soon.) The capability to easily and automatically identify this information, for comparison against published threat reports, will greatly aid automation users to address vulnerabilities in their devices.
