Remote Access for ICS - Ins, Outs, and Hidden Dangers (PDF, 2.68MB)Last updated: 19 Nov, 2025
Presented by:
Dieter Sarrazyn

Remote access to ICS environments was for a long time a no-go, yet during pandemic times all of a sudden these environments were connected to the Internet - in its good or bad ways - yet impact, implications and hidden dangers are often forgotten.

Nowadays, there is a debate what solution that should be used (supplier or asset owner provided solution).This talk will touch on the different aspects of a secure remote access and its hidden dangers, also links to NIS2 and IEC62443 will be mentioned.

Remote access

- The "bad" way - why it is important to have a secure remote access

- Requirements for secure remote access

- Possible "good" way

- Hidden dangers and how to counter these

- NIS2, IEC62443 & secure remote access
