Security in High Value Applications - Security in embedded systems must go beyond encryption and virus protection

摘要

Ten things you need to know about embedded system security but didn't know to ask. Lead Software Engineer and Project Manager, Digi International. The sad truth is, security is now a critical element in any embedded design. There are some obvious questions an engineer can ask when starting a project, such as 'what security package(s) do I need?' This is probably the first question an engineer might ask when faced with security as a requirement for an embedded systems application. Unfortunately, there are a large number of 'security packages' available, and an embedded engineer new to security may only know of security as encryption or virus protection. While encryption is a tool used for security, and virus scanners technically provide security, neither one likely provides what is needed. Fortunately, these days security is integrated into many applications and the packages you need are usually dictated by what your application will interface with.
