“I think we are communicating the wrong things to the wrong people inside the organization.”

— Daniel Miessler

Episode 0 is the exploration cut — 3 pieces drawn from the past two weeks of my reading, surfacing 1 different voices working the same problem: how the One-Person CISO operates when attackers are getting machine-fast and the business needs the answer in plain language. The scoring is honest about its uncertainty (most pieces sit in the 40-60 band), the feedback buttons are wired live, and every link goes to the original author — no aggregator redirects. Tell me what landed and what missed.

AI-enabled Self-software

via  Unsupervised Learning  · by Daniel Miessler  ·  1 min read
  • A solo CISO can now build bespoke security tooling without a dev team or enterprise budget.
  • The 'best features from multiple tools' constraint dissolves — custom detection logic costs only time.
  • Compliance dashboards, asset trackers, and alert triage tools are now zero-procurement, zero-vendor-lock-in.
  • Your opinionated CISO workflow, once coded, becomes a sellable asset to peers with identical constraints.
  • The bottleneck for one-person security programs has shifted from capability to imagination.

We Need a New Type of Cybersecurity Product

via  Unsupervised Learning  · by Daniel Miessler  ·  2 min read
  • The deliverable the business actually buys is a feeling of calm, not a count of controls or activities.
  • "Security" etymologically means without worry — invoking that feeling IS the program product, not documenting what you did.
  • Framing attacker actions as actively blocked ('they can't because we do X') is more persuasive than listing your own defensive stack.
  • A narrative chain — goals → metrics → challenges → strategy → projects → budget → results — replaces chaotic activity reporting with a legible story.
  • Linking every dollar spent to a specific protection outcome converts security from a cost center to a visible, evidence-backed risk reduction.

Thoughts on Prompt Injection OPSEC

via  Unsupervised Learning  · by Daniel Miessler  ·  8 min read
  • Prompt injection attacks being unpatchable doesn't eliminate control value — mitigations still reduce real risk even without a complete fix.
  • The Metasploit precedent suggests sharing attack techniques publicly nets a defender advantage, shifting burden of proof onto those claiming disclosure causes net harm.
  • AI is front-ending enterprise systems faster than security postures mature, making prompt injection an immediate operational priority, not a theoretical one.
  • Withholding prompt attack libraries is security-through-obscurity reasoning — a doctrine that has consistently failed across every other security domain.
  • Vague 'game-theoretic mathematical constraints' framing is a debate-stopper, not an argument — solo CISOs should demand concrete evidence before accepting it as policy rationale.
