    Here's your irregular reminder that infosec is a lot less of a technical discipline than is often thought and we really need you with your Liberal Arts degree. And also, that we're lucky to have .

    1/5 A story time thread 🧵 I consider today to be my “ anniversary” because it was 4 years ago today that with shaking hands I walked my resignation letter down the hall to my boss’s office. I spent 15 years as a librarian, mostly in law firms, and took a leap of faith.

    Infosec products: - don’t have to be grudge-purchases; - don’t have to look like they were written for Windows 3.1; - don’t have to be crazy expensive; - can absolutely be built with ❤️

    We are excited to be rolling out another Canary deployment to one of our clients. Appears to be built with ❤️.

    I love watching the evolution of this course over the years to ensure it provides up-to-date, practical skills for Windows enterprise defenders.

    My new six-day PowerShell course at SANS is going to make people FREAK OUT when they see what you can do with PowerShell Core 7 + OpenSSH for Windows. :-) ( )

    Having rolled out 2FA at scale twice, I wouldn’t describe it as easy. Easy in concept maybe, execution inevitably comes with a lot of exception handling.

    I get what Jeffrey is saying but deploying 2FA at scale can be a hassle for many customers. This is the echo chamber thinking I referred to earlier bc it “seems” simple enough, wrong. If it were most orgs/people would have already done it. They need better & clearer guidance.
