Show Notes

Allan is joined by Sounil Yu, one of cybersecurity's most well-known contributors. Sounil has a long history in cybersecurity, and is also the inventor of The Cyber Defense Matrix and the DIE Triad.

Sounil and Allan discuss cyber resilience and contrast it with "antifragility", a notion introduced by Nassim Nicholas Taleb. Sounil argues that in cybersecurity, antifragility should be the goal, and not resilience.

Antifragility allows for stronger data protection, as it does not just survive stresses and attacks, but actually encourages them. Sounil explains how antifragility also neatly dovetails with his DIE (Distributed, Immutable, Ephermeral) Triad of data protection, which he contrasts with the CIA (Confidentiality, Intregrity, Avaiability) Triad in the context of the "pets vs. cattle" model.

Join Allan as he learns a great deal in a short amount of time from Sounil...
