Internet surveillance for national-security purposes is largely regulated by two legal authorities. The Foreign Intelligence Surveillance Act (FISA) largely regulates surveillance on US territory, while Executive Order (EO) 12333 largely regulates surveillance abroad. Surveillance programs conducted under FISA are subject to legal restrictions imposed by Congress and the courts, while surveillance programs under EO 12333 are conducted solely under the authority of the President.
The talk considers that possibility that the legal protections built into in FISA can be circumvented by exploiting the Internet's routing protocols. Specifically, we consider the possibility that routing hijacks can be used to deliberately divert American traffic abroad, where it can be collected under EO 12333. We analyze the lawfulness of using routing hijacks to circumvent FISA, and discuss how several newly-developed secure routing protocols might (or might not) prevent these hijacks. We conclude with a policy recommendation: Congress should expand FISA to cover the surveillance of any and all Internet traffic collected abroad.
