OWASP Top 10 2017: But is it fixed?

Months back, I called outright for the removal of “A7: Insufficient Attack Protection” from the OWASP Top 10. The OWASP Top 10 team recently published a second release candidate (RC2) for OWASP Top 10 2017—and A7, which was in RC1, is conspicuously absent. So is the Top 10 fixed?

Something special happened on Thursday that is very easily overlooked. Marketplace, an American Public Media program making economics accessible to normal folk, ran a story on how kids start honing their cyber security skills early. The angle: future jobs. A good angle considering we’re all short on staff these days.

Mobile: Different or same sh*t different day?

Is mobile security the “same problem” as web application security? Is it just “different day”? I’ve watched organizations and mobile thought leaders argue perspectives on this question back and forth for years. The answer is, of course, both. Mobile security inherits previous problems and solutions while bringing its own unique ones. Let’s get specific about what’s different and why.

Securing password digests, or how to protect lonely unemployed radio listeners

As we’re prone to say, “much ink has been spilt over the release of password digests” from LinkedIn and others. I’m, as is typical, profoundly disappointed in that amount of misinformation I’ve heard in security folks’ commentary on the problem and the underlying workings of digests, HMACs, and so forth.
