For IIoT end users, equipment owners, and operators, it is crucial to ensure that the endpoint is adequately tested for security conformance. For device manufactures and OEMs, it is crucial to ensure that their equipment is trustworthy, in terms of both hardware and software. Often, time-to-market pressures and accelerated development cycles compete with adequate security testing. However, security verifications should be integral to the product development life cycle. While some vulnerabilities may still escape, proper security testing can significantly reduce their number. The sooner a vulnerability is detected in the product life cycle, the lower the cost of its repair, which also improves operational savings and brand reputation.
Some of the security test approaches for embedded systems include:
