New XT-3305 Encryptor Features img

img The XT-3305 series of ethernet encryption products has a new member. The XT-3305S model now includes a serial RS-232 port with TCP/UDP terminal server functionality. The five physical ethernet ports are also configurable as one of three trusted or untrusted interfaces, allowing for a redundant/backup WAN connection through wireless/LTE-5G, satellite, or other WAN paths.

Modems Are Still Important img

img Many people think telephone line modems are relics of the past. This couldn't be farther from the truth. Modern modems are used in applications for remote data gathering from wind and solar farms, railroad communications, military communications (via wireline, satellite, and radio), and last-option Internet connections. They are commonly used in ATM machines, vending machines, utility networks, two-way radio networks, and out-of-band management.

DCB has been building high quality modems for over 20 years using modern digital signal processing chips as well as traditional components.

XT Product Security In Perspective img

img Many agencies are now meeting their encryption requirements using our XT series of ethernet encryption products. These are easy-to-deploy, reliable, encryption bridges. This paper discusses encrypted tunneling bridges in general as well as standards requirments, how the XT products are used, and best practices configuration options. For more information, read the white paper. There's no registration required to download our white papers.

Ripple20 Malware Information img

img The latest malware going around is known as Ripple20.

The JSOF research lab discovered a series of zero-day vulnerabilities in a widely used low-level TCP/IP software library developed by Treck, Inc. The 19 vulnerabilities, given the name Ripple20, affect hundreds of millions of devices (or more) and include multiple remote code execution vulnerabilities. The risks inherent in this situation are high.

No products produced by DCB use the Treck or Elmic TCP/IP stack, or a TCP/IP stack derived from the Treck library. They are not subject to this vulnerability. The DCB Encrypted Tunnel product line uses the Linux TCP/IP stack for networking functionality. It is not impacted by the Ripple20 vulnerability.

DCB's COVID-19 Response img

img DCB is a decentralized company with employees based in four states. In normal times, we use our own products and a cloud-based telephone system to support our remote workers. By continuing to use these in-house tools, implementing healthy COVID-19 response rules was relatively straight forward. We do have a small staff on-site to manufacture, receive, and ship products. We continue to serve our customers with barely noticeable changes. Read our complete COVID-19 statement here.

Keep Your Firmware Current! img

img Firmware for our products is unusually reliable... defects are extremely rare. But, we are constantly improving firmware to add requested features. For example, the latest version of UT-Soft adds these features:
  • Support for managing multiple configuration files within UT-Soft. A new dialog was added that allows the user to select, edit, or create configuration files.
  • Support for storing the configuration files in an encrypted format. Encryption is AES-256. The key is generated from a user-supplied password.
  • Support for storing the Virtual Adapter's IPv4 configuration in the configuration file and applying the IPv4 configuration when UT-Soft connects.
  • Support for storing IPv4 routing table entries in the configuration file and applying the routes when UT-Soft connects.
  • Support for IPv4 packet filtering as packets are sent/received with the server.
  • Support for TCP mode. This allows UT-Soft to inter-operate with an ET server or an XT server in TCP mode.
  • Note: This version is backward compatible and may be installed on top of an existing installation without losing the configuration.
Like other manufacturers, we recommend using the latest version of firmware to take advantages of these improvements. And unlike many manufacturers, we don't charge for firmware updates. Check the firmware log here to see the latest version for your products.
