Jason Turner of C++ Weekly and Empty Crate spoke with us about the joy of puzzles, the changing directions of an interesting career, and the C++ programming language. I mean, of course we talked about C++. But only a little. Jason recently published , a book of puzzles for the logically minded. It teaches programming concepts as engaging puzzles: recursion, binary, assembly, Lisp, regular expressions. You may not know what you are learning but you’ll likely find you know a lot more about how computers work afterward. For the puzzles, paper is better than electronic. But you can...

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).
