Explore the concept of "Optimistic Security" in this 53-minute conference talk by Niall Merrigan at NDC Security in Oslo, Norway. Delve into how experience-based security approaches can be compromised by cognitive biases and mental shortcuts that affect decision-making processes. Learn through real-world examples how these biases can negatively impact both personal and business security postures, especially during security incidents. Examine your own security practices through an introspective lens to identify potential blind spots and biases that might be undermining your protection strategies. This thought-provoking session challenges conventional security wisdom and offers insights on how to develop more effective security mindsets beyond simply learning from past mistakes.
