I had a great meeting with the ISC2 Los Angeles Chapter on June 16, 2022, where I shared my experiences with the 3 lines model (also known as the three lines of defense.)

If you are curious about what the 3 lines model is or want some tips on what does and doesn’t work from someone who has lived with the model, please take a look at the presentation. I’d love any insight/input anyone may have as others will have different experiences.
