Excerpt

AIONSEC

Hello,

This is the first bi-weekly digest I’m sending out to share all the free educational material I’ve published, mainly YouTube videos and blog articles.

Over the past week, I published three videos + accompanying articles:

What Is an Agent Harness? A Security Perspective

An agent is more than its model. I explain what the harness does, how it turns a model’s responses into actions, and why engineering the system around the model matters so much.

The Foundational Problem of Using Agents for Security

Pointing an agent at a pile of raw logs doesn’t solve security’s data problem. I look at why that approach breaks down, and why we need a deliberately designed interface between our telemetry and the agent.

How Should Security Agents Use Data?

What should that interface actually look like? I explore two useful questions: when should the data be prepared, and how should it be represented to the agent? Timelines, alerts, summaries, and graphs each have a role to play.

I hope you find these useful. If there’s something you’d like me to cover in a future video or article, just reply and let me know, I LOVE to hear from you!

Have a great weekend,
Faan

The rhythm

Two weeks to make it worth opening.

I take my time with these. Two weeks gives me room to create new free lessons and videos for you, so every digest has real substance. It goes out every second Thursday at 10 am Eastern, and only when there’s something worth your time.
