Designers of the first electronic telephone switches nicknamed them the "large immortal machines" because switches last decades. The 1994 Communications Assistance for Law Enforcement Act (CALEA) requires that all digital-switched telephone networks be built wiretap enabled; the law took longevity of switches into account by authorizing funding to update switches in place. But by failing to analyze how threat models would change in a highly connected IP-based world, CALEA did not consider the longevity of switches prospectively. As an architected security breach, CALEA compliance is a ticking time bomb. Alleviating this is the subject of this talk.
