Schweitzer Engineering Laboratories (SEL) has released its SEL-3620 Ethernet security gateway. Designed to provide security to critical infrastructure systems, the gateway protects systems from malicious traffic with VPNs and a configurable ingress and egress stateful firewall. The storage for SEL-3620 offers industry-vetted security and interoperable standards, including IPsec (RFC 4301, 4302, and 4303), X.509 certificates, OCSP certificate revocation, IRIG-B time synchronization, HTTPS web interface, Cisco:OPSAID interoperability, and Syslog.

Suited to applications securing smart grid communications, the Ethernet Security Gateway operates with existing IT and control systems, using a menu-driven Web interface to create an IPsec (Internet protocol security) VPN. It secures routable protocols that cross electronic security perimeters, and provides up to 16 VPN connections on three Ethernet ports.

SEL says it designed and built the Ethernet Security Gateway as part of a cooperative project with the U.S. Department of Energy (DOE), Tennessee Valley Authority, and Sandia National Laboratories, among other partners.
