Networks are protected with multiple layers of cybersecurity, including securing access and permissions, detecting malware, encrypting data, and logging events.
These SEL devices have built-in malware detection or can identify nonauthorized network traffic.
These communications devices encrypt data streams for security.
Security devices collect critical event information to simplify audit reporting.
Devices with secure access authenticate users, control privileges, and create audit trails.
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.
