Classifying an operating environment of a remote computer
View Patent ↗Systems and techniques are provided for controlling requests for resources from remote computers. A remote computer's ability to access a resource is determined based upon the computer's operating environment. The computer or computers responsible for controlling access to a resource will interrogate the remote computer to ascertain its operating environment. The computer or computers responsible for controlling access to a resource may, for example, download one or more interrogator agents onto the remote computer to determine its operating environment. Based upon the interrogation results, the computer or computers responsible for controlling access to a resource will control the remote computer's access to the requested resource.
1. A method for classifying an operating environment of a remote computer, the method comprising:
maintaining a list of zones of trust in memory, each zone of trust associated with a set of resources; and
executing instructions stored in memory, wherein execution of the instructions by a processor:
selects a zone of trust from the list of zones of trust, wherein the selected zone of trust is defined by a signature comprising one or more literal values concerning a computer state,
compares the one or more literal values with a corresponding state of the operating environment of the remote computer, and
classifies the operating environment of the remote computer into the selected zone of trust when the one or more literal values are true for the operating environment, wherein classification into the selected zone of trust includes access to the set of resources associated with the selected zone of trust, wherein the list of zones of trust is further associated with a community of one or more users within a realm, the realm including one or more authorized users each associated with a remote computer and an authentication server.
2. The method of claim 1 , further comprising installing a process object on the classified remote computer, the process object for accessing a set of resources associated with the selected zone of trust.
3. The method of claim 2 , wherein the process object is a security process object.
4. The method of claim 1 , wherein the literal values include agent literal values.
5. The method of claim 1 , wherein the literal values include artifact literal values.
6. The method of claim 1 , wherein the one or more literal values are in conjunctive normal form.
7. The method of claim 1 , wherein the one or more literal values include a combination of agent literal values and artifact literal values.
8. A system for classifying an operating environment of a remote computer, the system comprising:
a policy server that:
maintains a list of zones of trust in memory, each zone of trust associated with a set of resources,
selects a zone of trust from the list of zones of trust, wherein the selected zone of trust is defined by a signature comprising one or more literal values concerning a computer state, and
compares the one or more literal values with a corresponding state of the operating environment of the authenticated remote computer; and
an end point control server for classifying the operating environment of the authenticated remote computer into the selected zone of trust when the one or more literal values are true for the operating environment, wherein classification into the selected zone of trust includes access to the set of resources associated with the selected zone of trust, and wherein the list of zones of trust is further associated with a community of one or more users within a realm, the realm including one or more authorized users each associated with a remote computer and an authentication server.
9. The system of claim 8 , wherein the signature for the selected zone of trust further includes a list of provisioned process objects required for accessing the set of resources associated with the selected zone of trust.
10. The system of claim 9 , wherein a process object from the list of provisioned process objects is installed on the classified remote computer, the installed process object for accessing a set of resources associated with the selected zone of trust.
11. The system of claim 10 , wherein the process object is a security process object.
12. The system of claim 11 , wherein the end point control server provides and activates the security process object.
13. The system of claim 8 , wherein the signature for the selected zone of trust further includes agents running on the remote computer.
14. A non-transitory computer readable storage medium having embodied thereon a program, the program being executable by a processor to perform a method for classifying an operating environment of a remote computer, the method comprising:
maintaining a list of zones of trust in memory, each zone of trust associated with a set of resources;
selecting a zone of trust from the list of zones of trust, wherein the selected zone of trust is defined by a signature comprising one or more literal values concerning a computer state;
comparing the one or more literal values with a corresponding state of the operating environment of the remote computer; and
classifying the operating environment of the remote computer into the selected zone of trust when the one or more literal values are true for the operating environment wherein classification into the selected zone of trust includes access to the set of resources associated with the selected zone of trust, and wherein the list of zones of trust is further associated with a community of one or more users within a realm, the realm including one or more authorized users each associated with a remote computer and an authentication server.
