Open Platform for Secure Edge Computing

Manageable, Secure and Reliable Edge Computers

Embedded computing is morphing into Edge computing, where systems deployed in the real world are always connected. While they are exposed to logical and physical attacks, they must be continuously monitored, secured and maintained. Deployments can involve hundreds of computers, a challenge which requires specific tools to achieve security, operational efficiency and business agility.

Kontron SEC-Line Open Platform includes two majors set of tools tackling these challenges: a firmware based on OpenWRT™ and OpCenter, its remote management console.
Combined with Kontron computers already qualified for demanding industry segments, the SEC-Line platform turns them into secured server routers ready for modern connected computing infrastructures.

SEC-Line Use Cases

According to the software payload profile required by the use case, choose the computer according to its performance.

Network security and management
lower range computers
network security
Router/Firewall only
(black box/no user code)
  • Black box
  • Security layer
  • Remote Management/updates
  • OpCenter On premises tools

Kontron firmware based on OpenWRT™ allows IT architects to implement the approved network security policy right into embedded computers like standard firewall/router equipment. Their network policy is then captured in per-system 'Settings profiles' in the on premises OpCenter for audits and re-use. This allows OT to deploy it further into new equipment without requiring network expert IT knowledge.

Legacy embedded applications
medium range computers
legacy applications
Secure computer with router/firewall base
for static or legacy workloads
  • Single VM for simple or legacy software
  • Security layer
  • Remote Management/updates
  • OpCenter On premises tools

Embedded computers for Legacy applications often come with old versions of OS and libraries. The virtualisation layer of Kontron firmware is used to protect and deploy them unmodified with their initial OS. The security comes from the hardware root of trust protected firmware which runs them in virtual machines augmented with modern firewall and multi-zone router and cyber defense mechanisms. This allows OT teams to continue using old stacks and safely deploy in modern, always connected mission profiles, with almost no code development. The firwmare is regularly updated to circumvent discovered vulnerabilities, while the application and its OS can remain the same.

Deploy IoT stacks side-to-side with existing applications
high end computers
IoT stacks
Secure server with router/firewall base
for large dynamic workloads
  • Multiple VMs for Edge Stacks
  • Security layer
  • Remote Management/updates
  • OpCenter On premises tools

Thanks to virtualization, IoT stacks can deploy on top of Kontron SEC-Line, side to side with existing applications. The hypervisor strictly controls the ressource consumption of each VM and container and the router/firewall is used by infrastructure engineers and network architects to distribute the data and the control flows within the computer and towards the selected physical connectors.
This allows a single computer to replace several existing systems without cabling redesign.

SEC-Line Firmware Demo

Kontron products powered by SEC-Line offer a hardware enforced secure firmware protecting customer software against cyber threats.

Operational applications run securely inside virtual machines, allowing payload insulation and consolidation. Virtual machines only connect through generic network connections, behind the local firewall and router. The complexity of multi-network management and low level hardware code is handled by the firmware itself. This way, the embedded software can stay simple, and delegate vulnerability management to the OpenWRT™-based firmware layer which has a small footprint and is maintained via updates from Kontron OpCenter.

Kontron products 'Powered by SEC-Line' feature:

  • Hardware Root Of Trust: all passwords, encryption keys and certificates within TPM
    • TPM-based Secure Boot preventing device refactoring
    • Measured boot using TPM hashing mechanism allowing Remote attestation
    • AppProtect technology for software licensing
  • Complete router/firewall based on OpenWRT
    • Control of device networking (wired, wireless, LTE, VPN)
    • Remote management of configations via OpCenter
    • Health monitoring engine, HIDS, etc.
  • Cyber Defense techniques
    • Monitoring Access Control: AppArmor restritcs software to only known usage patterns, seriously limiting the impact of exploits.
    • Host Intrusion Detection Service: OSSEC, intrusions detection, Blocking Brute Force Attacks.
  • Centralised management of all system settings
  • Virtual machines support based on QEMU
    • Standard computing VMs : protect legacy unprotected payloads behind SEC-Line embedded firewall and router
    • Complex DevOps stacks : enclose dynamic payloads inside a VM and control their resource consumption
    • Intelligent network VMs : Direct management of modems can be given to such a VM, just like on bare metal implementations, bypassing SEC-Line firmware
System GUI

SEC-Line powered systems offer a rich GUI interface used by network and cybersecurity experts to manage hundreds of settings. All the settings can then be captured from SEC-Line OpCenter in a single operation as a settings template. Templates can then be used by fleet operators to rebuild or duplicate a unit without the need for experts.

OpCenter : SEC-Line management console

Manage fleets of computers. Update SEC-Line firmware and settings from a single point.

Kontron OpCenter maintains all the data needed to manage and maintain all the computers in the fleet. From its console, remote computers firwmare can be updated, and their multiple network and security settings captured and stored. Settings can later be applied after device replacement at a simple click of a button. OpCenter can also import information from higher level asset management platform, avoiding manual data entry for device creation. It can also export all the fleet data to other corporate tools in various formats.

OpCenter manages operational network policies into computers powered by KSeOS. All settings for its firewall and router layers as well as the VM parameters are managed via OpCenter database, and deployed into all computers in the field from its GUI pages.

Manage edge computer fleets from a single console

With its standalone design, it aims at 'on premises' operation and is compatible with any IOT solution, or application stack selected by the customer.

Monitor via its GUI pages

Users can monitor remote systems and command updates of their firwmare, while restoring their network and cybersecurity settings. Secure and reliable operation is enforced via encrypted channels protocols designed to operate on very intermittent connections often found in mobile operations (trains, airplanes, etc.)

On-premises management tool

OpCenter allows on premises management of all the critical data needed by computers in the fleet, allowing easy rebuilt or replacement of a unit. Running as a standalone VM inside any infrastructure server, it maintains:

  • Deployed systems information
  • Computers Settings files
  • Encrypted images for security updates
  • *Software stacks images to initially provision VMs
  • *LoRa devices keys and deployment information
  • *when applicable
