An electronic device is secured by determining, by a processor, that an electronic device is in a first secured state associated with a first security level. Based on the first security level, a first context-dependent authentication policy is assigned to the electronic device. A transition rule is determined to have been satisfied, and responsively the electronic device transitions into a second secured state, wherein the second secured state comprises a different security level than the first secured state. The first context-dependent authentication policy is modified to yield a second context-dependent authentication policy, and the device is changed from the second secured state upon the device receiving an authentication that satisfies the second context-dependent authentication policy.
