Industrial automation manufacturers like Siemens, Allen-Bradley, Mitsubishi, Omron, Delta, and Schneider Electric implement password protection to safeguard intellectual property (IP) and prevent unauthorized modifications that could cause safety hazards or production downtime. Protection typically exists at multiple layers:

Use dedicated industrial software vaults (such as Versiondog, FactoryTalk AssetCentre, or Git-based OT repositories) to automatically back up code versions alongside their respective access credentials.

Cybersecurity researchers have identified that these tools often exploit legitimate software vulnerabilities while simultaneously infecting the user's workstation. Key Functional Features
