Rockwell Automation has issued an advisory urging users to disconnect industrial control systems from the internet as a proactive measure to reduce exposure to escalating cyber threats and geopolitical tensions. The recommendation is aimed at assessing and removing internet connectivity for devices not intended for online exposure, especially those without access controls. The advisory follows recent warnings from U
S. and international cybersecurity agencies about pro-Russian hackers targeting essential operational technology systems, such as water, energy, and agriculture, through unsophisticated techniques exploiting internet-exposed industrial control systems. Recommendations from the joint alert include implementing multifactor authentication, disconnecting programmable logic controllers, changing default passwords, and integrating cybersecurity practices into OT system design and development for better security measures. ```https://www.bankinfosecurity.com/rockwell-automation-urges-disconnection-ics-from-internet-a-25298
