Enough About Data Breaches. Let’s Talk About OT Security – TAG Cyber

Tag Cyber moderated a roundtable discussion with Mark Weatherford and me on control system cybersecurity.  The discussion was why operational technology (OT) is woefully neglected—and what can be done to change that. This discussion becomes even more timely with the recent DOE 100-Day Plan to Address Cybersecurity Risks to the US Electric System. The roundtable […]

Data center cybersecurity – don’t overlook the cyber vulnerable building control systems

According to many people, data is the new oil. Industries such as insurance, finance, retail, etc. depend on massive amounts of data from multiple data centers. However, what happens if you can’t get to your data because the data center infrastructure or servers have been damaged and are unusable? Data is merely a series of […]

The US food supply is neither cybersecure nor safe from control system cyber threats

The US FDA is supposed to assure the US food supply is safe from adulteration. However, the FDA Food Safety Management Act (FSMA) requirements ignore cyber threats. There have been more than 20 control system cyber incidents in food and beverage facilities including some where people were harmed and others that shut down facilities. Similar […]

Observations from 2021 SANS ICS Cyber Security Conference

The 2021 SANS ICS Cyber Security Conference was held March 4-5, 2021 with almost 9,000 registrants globally. The Conference thoroughly addressed OT networking issues. However, cyber security issues associated with Level 0,1 devices were not as adequately understood and addressed. There was also almost no discussion of the hardware backdoors in the Chinese-made transformers. My […]

Texas power outages demonstrate grid cyber vulnerability and inadequacy of existing regulations

Recent Texas power outages and the loss of both electricity and water across Texas demonstrate how vulnerable ERCOT and Texas are to not only natural disasters such as snowstorms and hurricanes but also manmade and malicious activities. More than that, it also demonstrates the vulnerability of the entire U.S. Energy grid. The good news is […]

Don’t overlook the most consequential control system cyber events of 2020

URL: https://www.controlglobal.com/blogs/unfettered/dont-overlook-the-most-consequential-control-system-cyber-events-of-2020/ Two of the most consequential control system cyber events (attacks) in 2020 were supply chain attacks. The first event was the Chinese installing hardware backdoors in large electric transformers, an incident that prompted Presidential Executive Order (EO) 13920. The hardware backdoors are obvious control system threats. The second event was the Russian SolarWinds […]

The SolarWinds hack can directly affect control systems

A highly sophisticated Russian Intelligence group has compromised the SolarWinds Orion platform which has an estimated 18,000 customers and an unknown but vast number of sites. The SolarWinds advisories and webinars have focused on the IT networks, network visibility, and data exfiltration/compromise. However, SolarWinds is also used to directly monitor and CONTROL SNMP devices including […]
