Why is it so hard to secure embedded applications?
Securing embedded applications is particularly challenging due to the interdependence of hardware and software in these systems. Testing them for security and functional issues is crucial.
Many embedded system industries (automotive, MedTech, aviation, etc.) operate with tight staffing and long development cycles, often under strict deadlines. When time gets tight, software testing can be overlooked in favor of releasing a product that is 'good enough.'
From a technical perspective, early stages typically involve testing hardware independently of the software to ensure compliance with physical requirements and standards (e.g., electromagnetic compatibility). Later in the process, the final hardware must be tested alongside the software.
After completion, the software is integrated into the target platform, and integration tests are performed. The entire process is extremely challenging. Download the guide.
