Security gateway protects networks for critical infrastructure

Device helps provide protection from malicious Ethernet traffic for water treatment, oil & gas, power utilities, etc.


SEL Gateway

Security Gateway performs firewall functions

Schweitzer Engineering Laboratories (SEL) has announced that its new SEL-3620 Ethernet Security Gateway is now available with competitive pricing. 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 company says it provides up to 60,000 security event reports and supports Syslog with precise time tagging of events through IRIG. 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 an intuitive, 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. "The SEL-3620, an OPSAID-compliant device, can provide a synergistic solution that benefits specific needs in securing our critical infrastructure, including smart grid communications," says DOE deputy assistant secretary Hank Kenchington. "This is a good example of the Department of Energy, a national laboratory, and a private company working together to provide useful solutions to critical needs in a timely fashion."

Annual Salary Survey

After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.

The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
