Tri-State Generation and Transmission Association steps up network security across its critical infrastructure
The risk of a cyber attack shutting down the national power grid is real, and Tri-State Generation and Transmission Association is implementing tougher network security measures to keep the lights on for 1.5 million customers.
"Cyber attacks are always a concern,' said Dave Buffo, Tri-State senior IT security administrator. "We needed to know what was going on with our internal hosts – what they’re doing, who they're talking to, and why.'
"Vectra gives us visibility into our networks, so we can monitor our internal hosts and address security issues in real-time," he said.
Automated, real-time network security
To detect attacks in progress, Vectra continuously monitors Tri-State's internal and Internet-bound network traffic. The highest-risk detections are prioritized so Buffo can quickly mitigate the most serious threats and avert damage.
Each Vectra detection includes severity and certainty scores as well as contextual information about the progression of a threat relative to hosts and key assets.
Augments intrusion prevention
Tri-State also relies on firewalls and intrusion prevention systems (IPS) and endpoint antivirus, but they didn’t always do what Buffo needed.
The IPS was actually blocking behavior that wasn't dangerous. "Our systems were working correctly but the IPS would still block traffic," said Buffo.
"Vectra is smart and knows what is and isn't a threat," said Buffo. "Vectra was the right choice for our environment."

This ESG Lab Spotlight explores the Cognito platform, which perform real-time detection and analysis of cyberattacks. The security landscape is bleak, and is only getting worse. Vectra is a promising next step toward a more secure infrastructure.
IT security is an ongoing exercise in ROI and operational efficiency. Organizations have a limited set of resources to address an unlimited set of risks, threats and attackers. This asymmetry means that security products must always be evaluated in terms of efficacy as well as their impact on the operational fitness of the organization.
