Method and apparatus for detecting grid intrusions
View Patent ↗A method, apparatus, and computer instructions for authorizing a user to access grid resources. A request is received from the user to access a resource on the data processing system. This request includes a certificate. An authentication process is performed using the certificate when the request is received. In response to successfully authenticating the user in the authentication process, a first host name for the certificate is requested from a trusted source. A reply containing the first host name is received. Access to the resource is provided if the first host name returned by the trusted source matches a second host name for the user from which the request originated.
1. A data processing system for authorizing a user to access grid resources, the data processing system comprising:
receiving means for receiving a request from the user to access a resource on the data processing system, wherein the request includes a certificate;
performing means, responsive to receiving the request, for performing an authentication process using the certificate;
requesting means, responsive to successfully authenticating the user in the authentication process, for requesting a first host name for the certificate from a trusted source; and
providing means, responsive to receiving the first host name, for providing access to the resource if the first host name returned by the trusted source matches a second host name for the user from which the request originated.
2. The data processing system of claim 1 , wherein the trusted source is a certificate authority.
3. The data processing system of claim 1 , wherein the requesting means is a first requesting means and further comprising:
second requesting means, responsive to successfully authenticating the user in the authentication process, for requesting a revocation list from the trusted source;
determining means for determining whether the certificate has been revoked using the revocation list; and
preventing means for preventing access to the resource if the certificate has been revoked.
4. The data processing system of claim 1 , wherein the certificate is a proxy certificate, wherein the proxy certificate is valid only for a selected period of time.
5. The data processing system of claim 1 , wherein the first host name is for a client data processing system for the user and is registered with the trusted source when the certificate is issued.
6. The data processing system of claim 1 , wherein the certificate is an X.509 certificate.
7. The data processing system of claim 1 , wherein the access to the resource is to run a task on the data processing system.
8. The data processing system of claim 1 , wherein the data processing system is part of a grid.
9. A computer program product in a computer readable medium for authorizing a user to access grid resources, the computer program product comprising:
first instructions for receiving a request from the user to access a resource on the data processing system, wherein the request includes a certificate;
second instructions for responsive to receiving the request, performing an authentication process using the certificate;
third instructions, responsive to successfully authenticating the user in the authentication process, for requesting a first host name for the certificate from a trusted source; and
fourth instructions, responsive to receiving the first host name, for providing access to the resource if the first host name returned by the trusted source matches a second host name for the user from which the request originated.
10. The computer program product of claim 9 , wherein the trusted source is a certificate authority.
11. The computer program product of claim 9 further comprising:
fifth instructions, responsive to successfully authenticating the user in the authentication process, for requesting a revocation list from the trusted source;
sixth instructions for determining whether the certificate has been revoked using the revocation list; and
seventh instructions for preventing access to the resource if the certificate has been revoked.
12. The computer program product of claim 9 , wherein the certificate is a proxy certificate, wherein the proxy certificate is valid only for a selected period of time.
13. The computer program product of claim 9 , wherein the first host name is for a client data processing system for the user and is registered with the trusted source when the certificate is issued.
14. The computer program product of claim 9 , wherein the certificate is an X.509 certificate.
15. The computer program product of claim 9 , wherein the access to the resource is to run a task on the data processing system.
16. The computer program product of claim 9 , wherein the data processing system is part of a grid.
17. A data processing system comprising:
a bus system;
a memory connected to the bus system, wherein the memory includes a set of instructions; and
a processing unit connected to the bus system, wherein the processing unit executes a set of instructions to receive a request from a user to access a resource on the data processing system, wherein the request includes a certificate; perform an authentication process using the certificate, in response to receiving the request; request a first host name for the certificate from a trusted source, in response to successfully authenticating the user in the authentication process; and provide access to the resource if the first host name returned by the trusted source matches a second host name for the user from which the request originated, in response to receiving the first host name.
