I've updated my one-lecture journalism security primer, from a talk at the Kiplinger Fellows program at Ohio State yesterday.
Includes:
Basic digital security precautions that everyone in a news organization should take (2FA, phishing, disk encryption)
How to think strategically about security (threat modeling)
Recipes to solve specific reporting problems (secure communication, handling leaks, crossing borders, and so on.)
Edit: I had the wrong URL before (went to my channel, not this specific video)
