Pervasive network connectivity increasingly forces engineers to confront and solve a wide range of technical security and reliability issues. Very few product classes remain that are not racing to feature Internet accessibility, and the resulting vulnerability has become an inevitable challenge. The more embedded devices operate in open network environments, the more security becomes a horizontal technology issue for virtually every embedded design. But embedded system developers have classically faced steep cost and time-to-market compromises in exchange for ensuring consistently reliable operation and security.

This paper uses automotive telematics to illustrate the need for embedded security and reliability assurance, and explains how the blending of hardware and software technologies from Analog Devices and Green Hills Software eliminate the previously inevitable compromise between security, cost and time-to-market. The result is a high reliability, high security, memory-protected RTOS running on a high-performance, low-cost, low-power, memory-protected processor complemented by a development environment that facilitates fast time-to-market.
