The problem facing many product teams is that embedded software developers don’t have sufficient security experience. Lack of experience can lead to overlooked security requirements, security gaps, and poor implementation. The result is connected systems that are poorly protected and are low‑hanging fruit for theft of intellectual property, along with device and user data.

Also, excessive noise while operating will cause customer complaints and an inordinate number of repair calls. In addition, poor cooling can rack up costs. While noise, vibration, and temperature increases are almost inevitable, they need to be minimized.
