Networks are protected with multiple layers of cybersecurity, including securing access and permissions, detecting malware, encrypting data, and logging events.
Devices with secure access authenticate users, control privileges, and create audit trails.
Security gateways combine cybersecurity capabilities to create secure access paths through security perimeters.
Firewalls control incoming and outgoing network traffic and are often integrated into routers.
Routers forward data packets to and from different networks. In utility networks, routers are often used to create security perimeters around substation LANs.
Password management is a critical cybersecurity element that includes enforcing strong passwords on IEDs and changing passwords on a schedule.
