receiving, at the policy server, a verification that the predetermined number of user devices provided secret information for booting a remote system; and
providing, from the policy server and in response to the received verification, a message for a key server to provide a booting key to the remote system, the key server providing the booting key to the remote system in response to the message and causing the remote system to complete a booting procedure, in response to the message from the policy server, wherein the policy server and the key server are separate machines, wherein communication between the policy server, the key server, and the remote system occurs via a first encrypted tunnel connecting the policy server to the key server and a second encrypted tunnel connecting the key server to the remote system, wherein the policy server and the key server are part of a first running instance of a fully encrypted system, wherein a second running instance of the fully encrypted system is used to decrypt the first running instance, wherein the first running instance and the second running instance are part of a plurality of running instances of the fully encrypted system, and wherein, if all of the plurality of running instances are offline, one of the plurality of running instances is decrypted manually.
2. The policy server of claim 1 , wherein the remote system comprises a virtual system, a container, or a hypervisor.
3. The policy server of claim 1 , wherein the remote system comprises a remote client machine or a remote server.
4. The policy server of claim 1 , the operations further comprising:
receiving, at the policy server, an indication that the remote system has initiated the booting procedure; and
responsive to the indication, prompting for the verification from a plurality of user devices, the plurality of user devices including the predetermined number of user devices.
5. The policy server of claim 4 , the operations further comprising:
receiving, at the policy server, data from a log of the remote system, the data indicating occurrences that occurred prior to the remote system needing to reboot; and
providing the received data to the plurality of user devices together with prompting for the verification from the plurality of user devices.
6. The policy server of claim 1 , wherein the policy server comprises the key server, and wherein the key server stores a plurality of booting keys for a plurality of remote systems, and a mapping of remote system identifiers to booting keys.
7. The policy server of claim 6 , wherein the key server provides the booting key to the remote system via the second encrypted tunnel.
8. The policy server of claim 1 , wherein the verification that the predetermined number of user devices provided the secret information is received via an additional encrypted tunnel connecting the predetermined number of user devices with the policy server.
9. The policy server of claim 1 , wherein the message for the key server to provide the booting key to the remote system is transmitted from the policy server to the key server via the first encrypted tunnel.
10. The policy server of claim 1 , wherein the verification from the predetermined number of user devices is received via a push notification or via a mail server.
11. The policy server of claim 1 , wherein the message for the key server to provide the booting key to the remote system comprises authenticated information for providing the booting key to the remote system.
12. A non-transitory machine-readable medium storing instructions that, when executed by the one or more processors of a machine, cause the one or more processors to perform operations comprising:
predetermining, based on a security threat level, a number of user devices;
receiving, at a policy server, a verification that the predetermined number of user devices provided secret information for booting a remote system; and
providing, from the policy server and in response to the received verification, a message for a key server to provide a booting key to the remote system, the key server providing the booting key to the remote system in response to the message and causing the remote system to complete a booting procedure, in response to the message, wherein the policy server and the key server are separate machines, wherein communication between the policy server, the key server, and the remote system occurs via a first encrypted tunnel connecting the policy server to the key server and a second encrypted tunnel connecting the key server to the remote system, wherein the policy server and the key server are part of a first running instance of a fully encrypted system, wherein a second running instance of the fully encrypted system is used to decrypt the first running instance, wherein the first running instance and the second running instance are part of a plurality of running instances of the fully encrypted system, and wherein, if all of the plurality of running instances are offline, one of the plurality of running instances is decrypted manually.
13. The machine-readable medium of claim 12 , wherein the remote system comprises a virtual system, a container, or a hypervisor.
14. The machine-readable medium of claim 12 , wherein the remote system comprises a remote client machine or a remote server.
15. The machine-readable medium of claim 12 , the operations further comprising:
receiving an indication that the remote system has initiated the booting procedure; and
responsive to the indication, prompting for the verification from a plurality of user devices, the plurality of user devices including the predetermined number of user devices.
16. The machine-readable medium of claim 15 , the operations further comprising:
receiving data from a log of the remote system, the data indicating occurrences that occurred prior to the remote system needing to reboot; and
providing the received data to the plurality of user devices together with prompting for the verification from the plurality of user devices.
17. The machine-readable medium of claim 12 , wherein the verification that the predetermined number of user devices provided the secret information is received via an additional encrypted tunnel connecting the predetermined number of user devices with the policy server.
18. The machine-readable medium of claim 12 , wherein the message for the key server to provide the booting key to the remote system is transmitted from the policy server to the key server via the first encrypted tunnel.
19. The machine-readable medium of claim 12 , wherein the verification from the predetermined number of user devices is received via a push notification or via a mail server.
20. A method comprising:
predetermining, based on a security threat level, a number of user devices;
receiving, at one or more processors of a policy server, a verification that the predetermined number of user devices provided secret information for booting a remote system; and
providing, from the policy server and in response to the received verification, a message for a key server to provide a booting key to the remote system, the key server providing the booting key to the remote system in response to the message and causing the remote system to complete a booting procedure, in response to the message from the policy server, wherein the policy server and the key server are separate machines, wherein communication between the policy server, the key server, and the remote system occurs via a first encrypted tunnel connecting the policy server to the key server and a second encrypted tunnel connecting the key server to the remote system, wherein the policy server and the key server are part of a first running instance of a fully encrypted system, wherein a second running instance of the fully encrypted system is used to decrypt the first running instance, wherein the first running instance and the second running instance are part of a plurality of running instances of the fully encrypted system, and wherein, if all of the plurality of running instances are offline, one of the plurality of running instances is decrypted manually.
