Abstract:
1. A computer-implemented method for protecting a computer system from accessing malicious network resources, the method comprising: receiving a request to access a resource, wherein the request includes an identification of the resource; determining a reputation of the requested resource, wherein the reputation indicates a likelihood that accessing the resource will cause malicious content to be downloaded to the computer system; determining a health state of the computer system from which the request is received, wherein the health state indicates a relative risk of allowing the computer system to access potentially malicious resources; accessing an access policy that identifies one or more conditions based on the resource reputation and computer system health state for which the computer system is allowed to access the requested resource; and applying the access policy to determine whether to allow the computer system to access the requested resource based on the access policy and thereby protect the computer system from accessing malicious network resources, wherein the access policy allows a computer system with a high health state to access a broader range of resources than a computer system with a low health state, wherein the preceding steps are performed by at least one processor.
