Protecting critical systems during the Coronavirus pandemic

As COVID-19 forces organizations to rethink how they work, chief information security officers (CISOs) who are responsible for the resilience of critical systems have an even greater dilemma.  How do you keep critical systems running 24/7 when employees are strongly encouraged to work from home and ever so dependent on secure connectivity to function normally? CISOs may need to open up systems that are traditionally closed to the outside world to allow for remote management. They must balance safety, productivity and cybersecurity risk.

Trump Ban on Foreign Bulk Power Equipment Triggers New Uncertainty

The most pronounced pushback perhaps came from the cybersecurity industry, whose services many power generators rely upon to monitor and respond to threats. Edgard Capdevielle, CEO at Nozomi Networks, a firm that promotes network visibility, threat detection, and operational insight for industrial operational technology (OT), the internet of things (IoT), and ICS environments, told POWER the EO is a “step in the right direction, but needs to go further.” The positive aspects in the order include its recognition that protecting the BPS is of critical importance owing to the proliferation of threats. “It seeks to address a potential vector of attack in the backdoors and trojans that could be implanted in foreign-sourced infrastructure equipment,” said Capdevielle.
