Dynamically Generating Perimeters

A mobile device, comprising:

• one or more processors operable to:
• receive a request to add to a mobile device an account setting for a server resource account;
• detect a trigger event for a new perimeter based on the account setting;
• in response to a parameter or a pattern associated with the account setting, retrieve a security policy from a resource server for the server resource account;
• and
• generate, by the mobile device, the new perimeter including the server resource account based on the security policy, wherein the new perimeter is configured to prevent access to resources associated with the server resource account to mobile-device resources external to the new perimeter.

A computer program product encoded on a tangible, non-transitory storage medium, the product comprising computer readable instructions for causing one or more processors to perform operations comprising:

• receiving a request to add to a mobile device an account setting for a server resource account;
• detecting a trigger event for a new perimeter based on the account setting;
• in response to a parameter or a pattern associated with the account setting, retrieving a security policy from a resource server for the server resource account;
• and
• generating, by the mobile device, the new perimeter including the server resource account based on the security policy, wherein the new perimeter is configured to prevent access to resources associated with the server resource account to mobile-device resources external to the new perimeter.
