First Line of Defense
Designing security into a device requires an understanding of the nature of the attacker. The cost of security implementation, including acquiring the technology carrying out the processes, scales up with attacker sophistication. A rule of thumb is to make the device tampering cost higher than the benefits gained from a security breach.
Wind River’s VxWorks real-time operating system platforms come with a set of simple security measures that protect the VxWorks applications against some clever hackers. At the Intel Developers Forum (IDF) in San Francisco next week, we will be demonstrating several layers of protection that come with the operating system (booth No. 400).
In this blog post I will outline a few simple security measures, already available in the VxWorks platform, that deter attacks on the VxWorks system.
