Determining source of side-loaded software using an administrator server

A method, comprising:

• receiving, by a first computing device from at least one of plurality of computing devices, a first application identifier and a first source identifier, each for a first application;
• receiving, from a third computing device, a second state designation for the first application, the second state designation representing a trusted state or an untrusted state;
• in response to receiving the second state designation setting, by the first computing device, a first state designation for the first application, wherein the first state designation is to be used for setting a state on a second computing device, and wherein the first state designation is different than the state represented by the second state designation;
• and
• sending, by the first computing device, the first state designation to the second computing device.

A non-transitory computer-readable storage medium storing computer-readable instructions, which when executed, cause a first computing device to:

• receive, from a second computing device, a first application identifier and a first source identifier, each for a first application;
• send the first application identifier and the first source identifier over a network to a third computing device;
• receive, from the third computing device, a first state designation for the first application, the first state designation representing a trusted state or an untrusted state;
• in response to receiving the first state designation, set a second state designation, wherein the second state designation is different than the state represented by the first state designation;
• and
• send the second state designation to the second computing device;
• wherein the second computing device is configured to store an application state for the first application, set the application state to untrusted in response to receiving the second state designation, and disallow the first application in response to setting the application state to untrusted.
