20090144545 | COMPUTER SYSTEM SECURITY USING FILE SYSTEM ACCESS PATTERN HEURISTICS - A system for computer system security using file system access pattern heuristics is provided. The system includes access patterns to establish nominal read and write frequencies to a file system using heuristics, dynamic policies, and a policy manager. The policy manager monitors accesses to the file system to determine read and write access frequencies to the file system. The policy manager also compares the read and write access frequencies to the access patterns, and determines whether the read and write access frequencies exceed the access patterns per the dynamic policies. The policy manager further identifies an attack on the file system in response to exceeding the dynamic policies, where the identified attack is associated with a communication path to the file system. The policy manager additionally modifies an aspect of access via the communication path in accordance with the attack response in the dynamic policies to mitigate the attack. | 06-04-2009 |

20090282481 | METHODS, HARDWARE PRODUCTS, AND COMPUTER PROGRAM PRODUCTS FOR IMPLEMENTING INTROSPECTION DATA COMPARISON UTILIZING HYPERVISOR GUEST INTROSPECTION DATA - Introspection data comparison is implemented utilizing hypervisor guest introspection data. A hypervisor shim on a hypervisor is used to construct one or more workload management components that are independent from a participating pool member of a pool comprising a guest having a guest memory and a guest operating system. The hypervisor collects a first set of data. The guest sends a second set of data comprising guest memory data from the guest memory. The first set of data is compared with the second set of data to detect at least one of a potential security intrusion or an anomalous deviation between the first set of data and the second set of data. A policy manager takes action based upon a result of the comparison of the first and second sets of data. | 11-12-2009 |
