1. A method comprising:
determining, by a computing system, a level of trust that a first network device has for a second network device;
determining, by the computing system, a level of trust that the second network device has for a third network device;
determining, by the computing system, that the first network device is separated from the third network device by the second network device;
determining, by the computing system and based on the level of trust that the first network device has for the second network device and further based on the level of trust that the second network device has for the third network device, a level of trust that the first network device has for the third network device;
enabling, by the computing system and based on the level of trust that the first network device has for the third network device, the first network device to perform an operation with the third network device;
detecting, by the computing system, a change in the level of trust that the first network device has for the second network device; and
adjusting, by the computing system, based on the change in the level of trust that the first network device has for the second network device, the level of trust that the first network device has for the third network device.
