The Pennsylvania Public Utility Commission (PUC) has issued a cybersecurity advisory to all regulated utilities and licensed electric and natural gas suppliers due to increased international tensions. The advisory outlines recommended practices for safeguarding critical infrastructure, emphasizing the need for heightened vigilance and stronger cyber defenses.

Key recommendations include isolating sensitive operational systems from the public internet, using strong passwords, and improving incident response planning. The PUC urges utilities to stay alert for sophisticated cyber techniques and to review guidance from the U.S. Department of Homeland Security's Cybersecurity and Infrastructure Security Agency (CISA).
