Abstract

A method, system, and computer program product for cross-domain access prevention are provided. The method includes detecting a request from a first domain to access a second domain, and applying cross-domain access heuristics to determine whether to allow the request. The cross-domain access heuristics define common ownership characteristics between the first domain and the second domain. The method further includes performing the requested access in response to determining that the request complies with at least one of the cross-domain access heuristics, and blocking the requested access in response to determining that the request fails to comply with the cross-domain access heuristics.

Claims

1. A method comprising:

accessing, via a processor, web-enabled content in a first domain including automatically executing a script in the content to receive request access to a web page in a second domain, the script being embedded in the web-enabled content;

detecting, via the processor, the request from the first domain to access the second domain;

applying, via the processor, cross-domain access heuristics to determine whether to allow the request, the cross-domain access heuristics defining determining common ownership characteristics between the first domain and the second domain;

executing, via the processor, a client domain resolver for determining an associated Internet Protocol (IP) address or subnet for the second domain and storing the associated IP address or subnet in at least one cache, the executing of the client domain resolver in response to failing to determine the common ownership characteristics between the first and second domains;

performing, via the processor, the requested access in response to determining that the request complies with at least one of the cross-domain access heuristics; and

blocking, via the processor, the requested access in response to determining that the request fails to comply with the cross-domain access heuristics; and

deleting, via the processor, the stored IP address or subnet in the at least one cache in response to the performing of the requested access or the blocking of the requested access.

2. The method of claim 1 wherein the cross-domain access heuristics further comprise allowing the request in response to determining that the first domain and the second domain have a common higher-level domain.

3. The method of claim 1 wherein the cross-domain access heuristics further comprise allowing the request in response to determining that the first domain and the second domain have a common Internet Protocol (IP) address or subnet.

4. The method of claim 1 further comprising:

querying domain registration data for the first domain and the second domain, wherein the cross-domain access heuristics further comprise allowing the request in response to determining that the first domain and the second domain are registered to a common owner.

5. The method of claim 4 wherein the common owner is determined as a function of similarity between registrants of the first and second domains as members of a common group.

6. The method of claim 1 further comprising:

accessing the at least one cache to determine the common ownership characteristics for the first and second domains,

initiating a request to a domain resolver for domain data in response to failing to locate the common ownership characteristics for at least one of the first and second domains in the cache.

7. The method of claim 1 further comprising:

enabling and disabling the detecting and applying in response to security settings of a web browser.

8. The method of claim 1 wherein the request is from hypertext transfer protocol (HTTP)-enabled content of the first domain to access HTTP-enabled content of the second domain.

9. The method of claim 1 wherein the access request from the first domain is initiated via one of a:

script, frame, embedded media, style sheet, include file, page loading, user action, and links invoked through modules on a page.

10. A system comprising a processor configured to perform a method, the method comprising:

a computer processing system configured to receive the request from the first domain including performing;

accessing web-enabled content in a first domain including automatically executing a script in the content to receive request access to a web page in a second domain, the script being embedded in the content;

detecting the request from the first domain to access the second domain;

applying cross-domain access heuristics to determine whether to allow the request, the cross-domain access heuristics defining determining common ownership characteristics between the first domain and the second domain;

executing a client domain resolver for determining an associated Internet Protocol (IP) address or subnet for the second domain and storing the associated IP address or subnet in at least one cache, the executing of the client domain resolver in response to failing to determine the common ownership characteristics between the first and second domains;

performing the requested access in response to determining that the request complies with at least one of the cross-domain access heuristics; and

blocking the requested access in response to determining that the request fails to comply with the cross-domain access heuristics; and

deleting the stored IP address or subnet in the at least one cache in response to the performing of the requested access or the blocking of the requested access.

11. The system of claim 10 further comprising:

a web browser executing on the processing system, the cross-domain access filter filtering hypertext transfer protocol (HTTP)-enabled content from the first domain accessed via the web browser.

12. The system of claim 10 wherein the cross-domain access heuristics further comprise allowing the request in response to determining that the first domain and the second domain have a common higher-level domain.

13. The system of claim 10 wherein the cross-domain access heuristics further comprise allowing the request in response to determining that the first domain and the second domain have a common Internet Protocol (IP) address or subnet.

14. The system of claim 10 wherein the cross-domain access filter further performs:

querying domain registration data for the first domain and the second domain, wherein the cross-domain access heuristics further comprise allowing the request in response to determining that the first domain and the second domain are registered to a common owner, the common owner determined as a function of similarity between registrants of the first and second domains as members of a common group.

15. A computer program product comprising:

a non-transitory, tangible computer readable storage medium readable by a processing unit and storing instructions for execution by the processing unit for implementing a method, the method comprising;

accessing web-enabled content in a first domain including automatically executing a script in the content to receive request access to a web page in a second domain, the script being embedded in the web-enabled content;

detecting the request from the first domain to access the second domain;

applying cross-domain access heuristics to determine whether to allow the request, the cross-domain access heuristics defining determining common ownership characteristics between the first domain and the second domain;

executing a client domain resolver for determining an associated Internet Protocol (IP) address or subnet for the second domain and storing the associated IP address or subnet in at least one cache, the executing of the client domain resolver in response to failing to determine the common ownership characteristics between the first and second domains;

performing the requested access in response to determining that the request complies with at least one of the cross-domain access heuristics; and

blocking the requested access in response to determining that the request fails to comply with the at least one of the cross-domain access heuristics; and

deleting the stored IP address or subnet in the at least one cache in response to the performing of the requested access or the blocking of the requested access.

16. The computer program product of claim 15 wherein the at least one of the cross-domain access heuristics further comprise comprising the method of allowing the request in response to determining that the first domain and the second domain have a common higher-level domain.

17. The computer program product of claim 15 wherein the cross-domain access heuristics further comprise comprising the method of allowing the request in response to determining that the first domain and the second domain have a common Internet Protocol (IP) address or subnet.

18. The computer program product of claim 15, wherein the method further comprising:
