“Cyber Threats to Our Nation’s Critical Infrastructure” is a great document from the Senate Judiciary Committee, detailing testimony by Professor James A Lewis.
'Looking specifically at the electrical power grid, which may be the most important national infrastructure, a general conclusion is that it is not adequately defended. This varies from company to company: some do a good job, while others do not. If you talk to cybersecurity experts with a deep knowledge of the industry and its control systems, they say we are vulnerable. Experts who investigated the Russian attacks against Ukrainian electrical facilities in 2015 and 2017 say the United States is absolutely vulnerable to similar Russian attacks on the power grid'.
Critical National Infrastructures of all countries is called 'critical' for good reason. The service outage last week of the UK's National Grid should be seen as a catalyst to ensure our systems are robust and secure, and by secure I mean truly secure.
CIP would be delighted to assist with the cryptography/PKI/Digital certificate foundation of the enterprises. If the PKI is flawed in anyway the entire security will also be compromised.
