Determining a security state designation for a computing device based on a source of software

A method, comprising:

• receiving a first application identifier for a first application to be installed on a first computing device;
• determining a first source identifier of the first application;
• sending the first application identifier and the first source identifier over a network to a second computing device;
• receiving, from the second 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, setting a second state designation;
• and
• sending the second state designation to the first 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 for a first application;
• determine a first source identifier of the 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;
• and
• send the second state designation to the second computing device.
