awesome-embedded-and-iot-security VS awesome-appsec

All the people saying embedded systems is too broad of a field to give you a straight answer are annoying as shit lol. Here are some generic resources that should guide you in a solid direction toward whatever you have planned: https://github.com/fkie-cad/awesome-embedded-and-iot-security The Hardware Hacking Handbook: Breaking Embedded Security with Hardware Attacks https://azeria-labs.com/

It looks like it could help, especially in the context of IoT and embedded Linux. You’ll still have a lot of blanks to fill in with respect to operational technology, hardware-based cybersecurity, distributed systems, etc. but any cyber-specific certification is better than none. Check out the Awesome Embedded Cybersecurity github for links and Azeria Labs for some good embedded cybersec content.

Embedded and IoT Security

Finally, this is very heavily biased towards security-research and IoT hacking, but there's a great list of books, tools, papers, etc here: https://github.com/fkie-cad/awesome-embedded-and-iot-security

AppSec

Here is a repo of some resources. You are going to need to learn to walk before you run so that at a concrete level you can articulate what secure vs insecure code is and why it matters, then dive into appsec. No disrespect intended but from the way this is written my suggestion would be to focus on computer science foundational concepts as well as spending significant time writing and reading code. This will likely be a several year journey if you are a total beginner but the best time to start is now :)

Come over to /r/devsecops to get more information about the field. Also, there are lots of good sources, you can get some from my blog, or Awesome AppSec, or Security Prince and other places.
