System and method for handling an event in a computer system

1. A system for handling an event in a computer system comprising:

at least one computing device having software executing thereon that is configured to

(a) suspend an occurrence of an event in a kernel-mode of an operating system running on said computing device;

(b) cause the event to occur in a user-mode of the operating system;

(c) determine if an occurrence of the event in the kernel-mode will compromise the computer system by analyzing the occurrence of the event in the user-mode; and

(d) execute at least one security measure if it is determined that the occurrence of the event in the kernel-mode will compromise the computer system;

wherein the security measure comprises denying an ability to write data to or read data from a file stored in a memory device of the computer system.

2. The system as claimed in claim 1 , wherein the security measure includes influencing an operation of the computer system based on the occurrence of the event in the user-mode.

3. The system as claimed in claim 2 , wherein the operation of the computer system is influenced by preventing the event from occurring in the kernel-mode.

4. The system as claimed in claim 1 , wherein the computing device is further configured to

run a user-mode software application operative to issue a request for the suspension of the occurrence of the event in the kernel-mode, and

run a first kernel-mode software module operable to use the request in order to activate a second kernel-mode software module operable to effect suspension of a class of events that comprises the event.

5. The system as claimed in claim 4 , wherein the second kernel-mode software module is further operable to interact with the operating system of the computer system in order to effect the suspension.

6. The system as claimed in claim 1 , wherein the event is selected from the group comprising a file system input/output based event, a network input/output based event, a memory management input/output based event, and a process management based event.

7. A method of handling an event in a computer system which has a kernel-mode and a user-mode, the method comprising the following steps performed by at least one computing device:

effecting a suspension of the occurrence of the event in the kernel-mode of an operating system running on said computer system;

effecting an occurrence of the event in the user-mode of the operating system;

determining if an occurrence of the event in the kernel-mode will compromise the computer system by analyzing the occurrence of the event in the user-mode; and

executing at least one security measure if it is determined that the occurrence of the event in the kernel-mode will compromise the computer system;

wherein the security measure comprises denying an ability to write data to or read data from a file stored in a memory device of the computer system.

8. The method as claimed in claim 7 , wherein the step of executing at least one security measure further comprises influencing an operation of the computer system based on the occurrence of the event in the user-mode.

9. The method as claimed in claim 8 , wherein the operation of the computer system is influenced by preventing the event from occurring in the kernel-mode.

10. The method as claimed in claim 9 , further comprising the steps of:

issuing a request for the suspension of the occurrence of the event in the kernel-mode; and

using the request in order to activate a kernel-mode software module that is operable to effect suspension of a class of events that comprises the event.

11. The method as claimed in claim 10 , further comprising the step of using the kernel-mode software module to interact with the operating system of the computer system in order to effect the suspension.
