Atom-based network security appliances focus on industrial control

Apr 23, 2019 — by Eric Brown 698 views

Lanner’s Apollo Lake based “LEC-6041” and Bay Trail “LEC-6032” are Linux-supported network security appliances for industrial control monitoring with up to 7x GbE ports, including SFP ports, plus magnetic isolation and extended temp support.

Lanner has combined two previously unveiled industrial network appliances into a thematically linked flashback announcement. We’d normally skip it, but we missed the original announcements and the category of industrial-focused network appliances deserves closer attention. The Intel Apollo Lake based LEC-6041 is fairly new — it was announced last September and should be shipping by now. The Bay Trail based LEC-6032 appears to have debuted in 2016, with a PoE-enabled LEC-6032E variant announced in Nov. 2017.

The LEC-6041 and LEC-6032 are billed as cybersecurity gateways for industrial control systems (ICS) in “harsh unmanned environments.” The systems offer multiple security services, including a network appliance stack with firewalls and unified threat protection, as well as SCADA network security.

The LEC-6041 and LEC-6032 have a legacy feel in that they ship with Windows 7, Windows 7 Embedded, and the similarly aging Linux 2.6. Other less rugged Lanner network appliances include last October’s Atom C3000 based NCA-1515.



The LEC-6041, which is said to be the successor of the Atom N2600 based LEC-6021, ships with a Lanner Edge Security Kit — a turnkey solution for endpoint authentication, software property protection, service lifecycle management, and advanced device/application monitoring. Other functions include protocol filtering, packet inspection, white-listings, and network traffic monitoring.

The 166 x 160 x 53.5mm system runs on a quad-core Intel Atom x7-E3950 or dual-core Atom x5-E3930 with 8GB DDR3L. A SATA port is available along with an optional 2.5-inch HDD bay. There are 5x copper GbE ports with 1-pair bypass and 2x SFP GbE ports with 1.5 KV magnetic isolation.

The LEC-6041 is equipped with an HDMI port, 2x USB 3.0 ports, and 2x RS-232 ports. The I/O ports are said to be protected with 15 KV isolation. The system is compliant with IEC 61850-3 and IEEE 1613 certifications for ESD protection.

A mini-PCIe slot is accompanied by a SIM slot with support for optional 4G LTE. A 6-pin terminal block supplies power, and there’s a reset button, watchdog, and optional TPM 2.0. The system supports -40 to 75°C temperatures.

The older, fanless LEC-6032 is smaller than the LEC-6041 at 146 x 127 x 78mm. It runs on a quad-core Atom E3845 from Intel’s aging Bay Trail family with up to 8GB DDR3L and has an optional, 2.5-inch SATA bay.

There are several LAN configurations, all with 1.5 KV isolation. The LEC-6032B has 5x copper, RJ45 GbE ports with 2x bypass pairs. The other models have 1-pair bypass. These include the 6032D with 5x RJ45, the 6032C with 5x RJ45 and 2x SFP, and the 6032F with 3x RJ45 and 4x SFP ports.


The LEC-6032 is equipped with single USB 3.0, USB 2.0, and RS-232 serial ports plus a second USB 2.0 header. The serial port is a DB-9 port on all but the LEC-6032B which has a pin header. The system has a 12-36V DC input, wall- and DIN-rail mounting, a watchdog, and -40 to 75°C support.

There’s also a separately listed LEC-6032E with Power-over-Ethernet (PoE) ports to connect IP security and industrial monitoring cameras. The LEC-6032E has 2x RJ45 GbE ports with 1-pair bypass plus 4x IEEE 802.3af compliant powered Ethernet ports. The system is limited to a -20 to 55°C range, but the Linux kernel bumps up to 3.0.

Further information

The LEC-6041 and LEC-6032 appear to be available now with undisclosed pricing. More information may be found on Lanner’s LEC-6041 and LEC-6032 product pages.
