  • Rooting Out Evil: What Cybersecurity Can Learn from the Secret Service

    It’s easy to break into networks, and it probably always will be, because a bad actor only has to be right once to get inside. It should be hard to stay hidden once they’re in, because each move could expose them. But today it isn’t. Intruders spent more than a year inside the DNC and six months inside OPM. If we’re going to make ourselves more secure, we don’t need to figure out how to keep intruders out — we need to figure out why we can’t catch them once they’re inside.
    The Secret Service offers a compelling model. There’s a reason that jumping the wrought iron fence at the White House is easy, but avoiding capture once inside is almost impossible. The Secret Service accepts porous boundaries and has used control of their environment to defend the President for more than a century. This talk will examine how the Secret Service protects the President, how their approach can improve cybersecurity, and what we need to do to get there.
