Cybersecurity Splashdown: Internet-Exposed HMIs Threaten Water Safety!
Internet-exposed Human Machine Interfaces (HMIs) pose cybersecurity risks to the Water and Wastewater Systems sector. Imagine hackers treating your water plant like their personal hot tub! To avoid such chaos, CISA and EPA urge securing HMIs with strong passwords, multi-factor authentication, and regular updates. Because nobody likes a surprise splash of cyber-chaos.
Hot Take:
Water you doing, HMI?! It seems our trusted water systems are making a splash on the cybercrime scene. Time to batten down the hatches and keep those thirsty hackers from diving into the deep end of our infrastructure!
Key Points:
- Internet-exposed HMIs are a significant cybersecurity risk for water and wastewater systems.
- CISA and EPA have released a fact sheet with actionable guidance to protect critical infrastructure.
- HMIs are prone to cyber-attacks that could disrupt water treatment processes and administrative control.
- Best practices include disconnecting HMIs from the internet, using strong passwords, and regular updates.
- CISA offers free vulnerability scanning services to help facilities identify and address security weaknesses.
