1. Multi-Layered Defense
Our cybersecurity strategy includes
a multi-layered approach to grid
protection. In our defense-in-depth
strategy, each layer acts as a virtual
“steel door” that can be locked
down in the event of a breach
isolating illicit traffic.
The first layer surrounding the core
includes advanced tools, technology,
processes and employee awareness measures designed to block, reduce and detect
threats before they cause impairment. Response to any disruptions is immediate to
maintain grid reliability.
The middle layer includes policies, training, employee education and separation of duties to
govern information transfers ensuring data confidentiality and integrity.
The outer security layer includes employee identification badges, authorized access
privileges, biometric identification, guards, CCTV and alarms.
Cybersecurity Collaborations
This defense posture is only part of the picture. Real-time information sharing from
local, state and federal agencies, as well as utility partners, provides an additional layer
of support.
Our mission is to assure grid safety and reliability, so our cybersecurity department
regularly engages key contacts in the following organizations:
• Department of Defense
• Department of Energy
• Department of Homeland Security
• Edison Electric Institute
• Electric Power Research Institute
• Electricity Sector Information Sharing Analysis Center
• EnergySec
• Federal Bureau of Investigations
• Lockheed Martin
• North American Electric Reliability Corporation
