3 Cybersecurity Myths to Bust Deeply rooted cybersecurity misconceptions are poisoning our ability to understand and defend against attacks. "Every lie is a poison; there are no harmless lies." Leo Tolstoy said this over 100 years ago, and who am I to argue with the great author? His observation holds as true today as ever — in many aspects in life, including cybersecurity. I attend many cybersecurity presentations in my work, and one thing that has bothered me the past several years is the (over)use of clichés, myths, and misconceptions. There are many cybersecurity myths out there, but the three that are the most deeply rooted in the cybersecurity world (and therefore are the most "poisonous," as Tolstoy would say,) relate to People, Process, and Technology.
