Functional Safety

We are the leading provider of development services in the area functional safety covering measurement, drive, and control technology, medical engineering, for the associated control devices and for components of collaborative robot systems. embeX was the first company worldwide to be awarded the highest maturity level for Functional Safety Management (FSM) according to IEC 61508 by TÜV Rheinland.

embeX develops embedded systems ranging from SIL 1 to SIL 4, from PL a to PL e, from medical device class I to III. We advise and support our customers in all issues relating to functional safety, when implementing a functional safety management system and during assessment and certification.

Our safety experts actively work in the safety standardisation groups such as IEC 61508 (SIL) and maintain constant contact with all renowned notified bodies.

• Safety & Security
  • Since according to IEC 61508-1 and the IEC TR 63074, a threat analysis must be carried out in case of foreseeable threats to IT security in order to determine the requirements for IT security, we also support our customers in all fields of security and the combination of safety and security.
• Functionally Safe Communication
  • Frequently implemented safe interfaces are:CANopen Safety, CIP Safety, FSoE, OPC UA Safety, IO-Link Safety, open Safety, PROFIsafe

Engineering Services

For the consistent implementation of the security-by-design concept, embeX works systematically according to a proven development process that is also available to customers for adoption. Our offer covers all aspects of development and product life cycle support:

Security Risk Analysis

• We prefer to use the STRIDE model
  • Spoofing
  • Tampering
  • Repudiation
  • Information disclosure
  • Denial of service
  • Elevation of privilege
• According to CIA Modell
  • Confidentiality
  • Integrity
  • Availablity
• According to AAA Modell
  • Authentication
  • Authorisation
  • Accounting

Secure Communication

• OPC-UA
• MQTT as basis
• Modbus TCP as basis
• Bluetooth
• WiFi
• ProfiNet as basis
• Customer specific solutions

Services during the Product Life Cycle

• Pen Tests
• Product Security Incident Response Team (PSIRT)

Protecting Functional Safety by Cybersecurity

• Safety & Security

Services

embeX offers the following services for PSIRT on behalf of customers at an unrivalled level of security:

• Consulting on the structure and processes for PSIRT
• Automated monitoring of security vulnerabilities in 3rd party libraries
• Notification of potential security vulnerabilities in products
• Assessment of vulnerabilities for relevance and criticality to products
• Elimination of vulnerabilities - provided that the code is available
• Four differente Service Level Agreements (SLA) for Product Maintenance

Your Advantages

• You relieve your development team of time-consuming routine tasks.
• You access the competence of the embeX experts.
• For security reasons, a cloud solution that stores code and vulnerability together is not used.
• Response times and scope of notifications are regulated in individual customer agreements.
• Optional black- / whitelisting
• Communication is always encrypted in two possible ways.

Engineering Services

In addition to the normative requirements, it should be noted in the product definition that a higher security level (SL) of a component such as a control system requires fewer protective measures to be taken externally. Since system considerations always require intensive coordination with the end user, embeX advises on the cost-benefit analysis of improved security protection, where further system components and coordination are not necessary.

The certified embeX development process covers both safety and security requirements and is made available to customers for adaptation on request.

On the one hand, synergies are created in the development of safe and secure products, as both areas place high demands on the care taken in development and predictable behaviour. On the other hand, it is necessary to strike a balance between a large number of opposing objectives of the security concepts on a project-specific basis.

KISS: Safe & Secure Platform for the IoT

The networking of functionally safe devices in the IoT environment requires the safeguarding of functional safety through suitable cybersecurity measures. embeX has developed the powerful and field-proven multiprocessor platform KISS for these diverse areas of application - KISS stands for “Keep It Save and Secure”. The platform covers the following core functions of cybersecurity:

• Implementation of access restrictions
• Use of secure and proven protocols
• Updateability of bootloader, operating system, application SW

The technical basis of the KISS multiprocessor platform is a Yocto-based embedded Linux with the following advantages for manufacturers:

• Highly efficient development through integration of modules
• Very large, constantly growing range of functions
• Future-proofing through upcoming advances in the Yocto project

Safety solutions from a wide range of standards (IEC 61508, ISO 13849, MDR, FDA, etc.) can be integrated into the KISS platform to get protected effectively and efficiently with regard to security.
