![]() Some embedded systems are easier to update than others. Including security in the design phase helps ensure that an embedded system has a way to get updates and is capable of running new software. As vulnerabilities are identified, they will need to be mitigated with patches, which require software updates. ![]() Computing, networking, cyberattacks and embedded systems security will evolve over the lifespan of an embedded system in ways that cannot be foreseen by system developers. Designing a system to be secure can greatly increase the viability of keeping systems safely in service and at reduced risk of attack.ĭevelopers need to consider hardware and software obsolescence when designing embedded systems to increase system longevity and security. Older embedded systems often don’t get updated because the hardware is obsolete and doesn’t support the new software. Many mission-critical systems, such as cars, defense systems and power plants, have a long service life - 20 years or more. Some embedded systems are in the field for decades, others for just a few years.
