Unfortunately, many embedded systems are not sufficiently protected. Above all, interfaces are not switched off.

System Hardening
As bad practices unfortunately are showing us: many embedded systems are unhardened, many physical interfaces in the field are completely open and easily accessible. This is a very simple attack vector that causes great damage, especially when hackers can easily extract the intellectual property behind the systems. Our services:
- Analysis of existing systems for weaknsses and vulnerabilities
- Penetration testing
- Creation of hardening concepts
- Securing existing platforms
- Concepts for hardening new platforms
- Security management
- Designing cybersecurity for future platforms
Application Hardening
Tough, tougher, toughest. This must apply to applications on embedded systems. Unfortunately, many of the systems examined show that this does not apply in many cases. The requirements of embedded systems are often not taken into account. In addition, security is often very weak, as such platforms are very weakly dimensioned at hardware level and the applications can then no longer be properly secured. We can help:
- Analysis of systems
- Weakness and gap analysis
- Development of target concepts
- Redesign of software platforms for adequate security solutions
- Security management of platforms
- Hardening of operating systems
- Hardening of applications and middleware
Case Study
Hardening of an embedded system at hardware level:
An investigation into compliance issues has shown that the hardware platform does not meet future security requirements and has a variety of other vulnerabilities. Among other things, there are brown-out scenarios (voltage glitch) that allow the target system to be hacked.
An analysis was carried out for the client in order to create a secure operating environment based on the existing board using a new CPU, MCU and memory and to fulfill performance reserves for the application and future security requirements such as R.E.D. and CRA.
No changes had to be made to the PCBs themselves, only the chips were replaced with larger memories and successor models of the processor.
