20100251368 | SYSTEM AND METHOD FOR HANDLING AN EVENT IN A COMPUTER SYSTEM - Systems for handling an event in a computer system which has a kernel-mode and a user-mode. The systems comprise at least one computing device. The computing device is configured to suspend an occurrence of the event in the kernel-mode of an operating system running thereon. The computing device is also configured to cause the event to occur in the user-mode of the operating system. The computing device is further configured to 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. If it is determined that the occurrence of the event in the kernel-mode will compromise the computer system, then the computing device executes at least one security measure. | 09-30-2010 |
20100138843 | SYSTEM AND METHOD FOR HANDLING AN EVENT IN A COMPUTER SYSTEM - Stack-based system for handling an event in a computer system which has a kernel mode and a user-mode, concurrently by one or more user-mode applications. The systems comprise at least one computing device. The computing device is configured to suspend an occurrence of the event in the kernel-mode of an operating system running thereon. The computing device is also configured to cause the event to occur in the user-mode of the operating system. The computing device is further configured to 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. If it is determined that the occurrence of the event in the kernel-mode will compromise the computer system, then the computing device executes at least one security measure. | 06-03-2010 |
20090288167 | SECURE VIRTUALIZATION SYSTEM SOFTWARE - Systems and methods for protecting a virtualization environment against malware. The methods involve intercepting an event in a kernel mode of the virtualization environment, suspending execution of the event, and transmitting the event to a user mode security module that determines whether the event should be blocked, allowed, or redirected. Events may be intercepted from any level of the virtualization environment, including an interrupt request table, device driver, OS object manager, OS service dispatch table, Portable Execution (P/E) import/export table, or binary code, among others. In one embodiment, an event may trigger a chain of related events, such that interception of an event without first intercepting an expected antecedent event is one indication of malware. The method also involves securing a virtual storage device against unauthorized access and providing for secure communication between guest OS and virtualization environment security modules. | 11-19-2009 |
20090187991 | TRUSTED SECURE DESKTOP - Systems and methods for simultaneously protecting software components ( | 07-23-2009 |
20090187763 | SYSTEM AND METHOD FOR PROTECTING DATA ACCESSED THROUGH A NETWORK CONNECTION | 07-23-2009 |
20090044266 | SYSTEM AND METHOD FOR PROVIDING TRANSACTIONAL SECURITY FOR AN END-USER DEVICE - A network system comprises a transaction network operative to provide a transaction with an end user; a trusted source of a security mechanism (e.g., a start/stop trigger module, an application lockout module, a network/file I/O control module, a trusted driver manager, a keystrokes generator driver, a keystrokes deletion hook, and/or a transaction network VPN manager) for at least partially protecting an end-user device from malicious code operative thereon that attempts to capture confidential data presented during the transaction, the security mechanism being maintained by a party other than the end user; and an agent for providing the security mechanism to the end-user device to protect the end-user device during the transaction | 02-12-2009 |
