In the United States, governments and utilities were paying attention to the fact that critical infrastructure should not be taken lightly. In 2013, President Obama issued Executive Order 13636 – Improving Critical Infrastructure Cybersecurity. One of the more interesting actionable items is:

Sec. 8. Voluntary Critical Infrastructure Cybersecurity Program. (a) The Secretary, in coordination with Sector-Specific Agencies, shall establish a voluntary program to support the adoption of the Cybersecurity Framework by owners and operators of critical infrastructure and any other interested entities (the “Program”).

The question then becomes: how do we identify and implement some mechanism to protect critical infrastructure? By “we,” I mean the utility trying to build a security posture with no prior knowledge.

In the case of the power transmission and distribution world, there are hard requirements to meet known as the NERC CIP requirements. These are put in place to protect the United States’ electrical (Read more...)
