Preventing Initial Access in Industrial Environments
Summary: Dragos analyzed the top MITRE ATT&CK for ICS Initial Access techniques used by its tracked Activity Groups and found that gaining access to a corporate/IT network was a more common mechanism for preparing a pivot into ICS/OT than direct access to ICS/OT technologies, which it calls the code red of initial access scenarios. Dragos says it does not publicly describe ICS/OT activity group technical details except in extraordinary circumstances, to limit tradecraft proliferation.
Key Takeaway: The perimeter you defend most heavily may not be the one adversaries use first: Dragos found corporate IT networks were the more common route into industrial environments, so an IT breach is a step toward the physical process, not a separate incident.
