515: Script Boomers

Embedded

Nick Kartsioukas joined us to talk about security in embedded systems.

Common Vulnerabilities and Exposures (CVE) is the primary database to check your software libraries, tools, and OSs: cve.org.

Open Worldwide Application Security Project (OWASP, owasp.org) has information on how to improve security in all kinds of applications, including embedded application security. There are also cheatsheets, Nick particularly recommends Software Supply Chain Security - OWASP Cheat Sheet.

Wait, what is supply chain security? Nick suggested a nice article on github.com: it is about your code and tools including firmware update, a common weak point in embedded device security.

Want to try out some security work? There are capture the flag (CTF) challenges including the Microcorruption CTF (microcorruption.com) which is embedded security related. We also talked about the SANS Holiday Hack Challenge (also see Prior SANS Holiday Hack Challenges).

This episode is brought to you by RunSafe Security.

Working with C or C++ in your embedded projects? RunSafe Security helps you build safer, more resilient devices with build-time SBOM generation, vulnerability identification, and patented code hardening. Their Load-time Function Randomization stops the exploit of memory-based attacks, something we all know is much needed. Learn more at RunSafeSecurity.com/embeddedfm.

Some other sites that have good information embedded security:

This World Of Ours by James Mickens is an easy read about threat modelling

Cybersecurity and Infrastructure Security Agency (CISA) is at cisa.gov and, among other things, they describe SBOMs in great detail

National Institute of Standards and Technology (NIST) also provides guidance:

Internet of Things (IoT) | NIST

NIST Cybersecurity for IoT Program

NIST SP800-213 IoT Device Cybersecurity Guidance for the Federal Government: Establishing IoT Device Cybersecurity Requirements

There is a group of universities and organizations doing research into embedded security: National Science Foundation Center for Hardware and Embedded Systems Security and Trust (CHEST). Descriptive overview and the site is nsfchest.org

European Telecommunications Standards Institute (ETSI) - Consumer IoT Security

Camera Ubiquiti configuration issue (what not to do)

Finally, Nick mentioned Stop The Bleed which provides training on how you can control bleeding, a leading cause of death. They even have a podcast (and we know you like those). Elecia followed up with Community Emergency Response Teams (CERT). Call your local fire department and ask about training near you!
