Abstract: The present invention relates to methods and apparatuses for securing otherwise unsecured computer communications that addresses the above shortcomings among others. According to certain aspects, the invention relates to methods and apparatuses for implementing device snooping, in which some or all traffic passing between a host and a connected device is captured into memory and analyzed in real time by system software. According to other aspects, the invention relates to real time capture of certain types of traffic and communication of the captured traffic to a remote management system. According to still further aspects, the invention relates to detecting security threats in real time. Upon threat detection, possible actions are blocking individual devices or alerting a system administrator. According to certain additional aspects, the security functions performed by methods and apparatuses according to the invention can be logically transparent to the upstream host and to the downstream device.

Abstract: According to certain general aspects, the present embodiments relate to providing a secure computer architecture in which a single computer is capable of simultaneously executing two operating systems. According to certain additional aspects, the two operating systems can have different security profiles and capabilities. According to still further aspects, the secure computer architecture further provides secure video conferencing capabilities, network activity monitoring and high performance computer graphics.

Abstract: The present invention relates to methods and apparatuses for establishing a “root-of-trust” path for a computing system. In embodiments, a secure computer system having such a root-of-trust path is implemented by a secure processor in conjunction with a host processor. The secure processor becomes the root-of-trust, providing authenticated and encrypted BIOS boot code for the host processor without the need to modify the host processor's operating system. In one embodiment, the establishment of a root-of-trust is implemented by the secure processor presenting itself to the host processor as an on-board BIOS flash device and the secure processor maintaining the integrity of the BIOS boot code. In additional or alternative embodiments, the establishment of the root-of-trust includes use of a direct communications channel and protocol between the host and secure processors.

Abstract: The present invention relates to providing security functionality over computer system mass storage data, and more particularly relates to a system and method of transparent data backup on either local or remote storage devices such as SATA storage devices. According to aspects of the invention, the system is transparent to operating system and application software layers. That makes it unnecessary to make any software modifications to the file system, device drivers, operating system, or applications, or installing specialized applications or hardware. In embodiments, the snapshot functionality of the invention is implemented entirely in hardware, and is not designed to slow down performance of the rest of the system.

Abstract: In general, embodiments of the invention include methods and apparatuses for securely storing computer system data. Embodiments of the invention encrypt and decrypt SATA data transparently to software layers. That makes it unnecessary to make any software modifications to the file system, device drivers, operating system, or application. Encryption key management is performed either remotely on a centralized Remote Management System or locally. Embodiments of the invention implement background disk backups using snapshots. Additional security features that are included in embodiments of the invention include virus scanning, a virtual/network drive, a RAM drive and a port selector that provides prioritized and/or background access to SATA mass storage to a secure subsystem.

Abstract: The present invention relates to a system and architecture for securing otherwise unsecured computer subsystems. According to one aspect, the invention provides an independent hardware platform for running software in a secure manner. According to another aspect, the invention provides the means to control and secure all disk, network and other I/O transactions. According to still further aspects, the invention provides a means to monitor and prevent unauthorized user and malicious software activity Additional aspects include providing a secure platform for device and user authentication as well as encryption key management, providing a means to perform background backup snapshots, and providing the means for enabling full management over computer operations.

Abstract: In general, embodiments of the invention include methods and apparatuses for securing otherwise unsecured computer audio and video subsystems. Embodiments of the invention perform watermarking of video and/or audio data streams output by a computer system. Additional security features that are included in embodiments of the invention include fingerprinting, snooping, capturing streams for local or remote analytics or archiving, and mixing of secure system content with local audio and video content.

Abstract: The present invention relates to a system that manages security of one or more computer systems and/or one or more different types of I/O channels such as USB, Ethernet, SATA, and SAS. According to certain aspects, the management system is distributed. That is, a central management system and computer subsystems are physically distributed within one or more geographical areas, and communicate with each other by passing messages through a computer network. According to certain additional aspects, the configuration and/or security functions performed by methods and apparatuses according to the invention can be logically transparent to the upstream host and to the downstream device.

Abstract: In general, the invention provides a computer architecture designed for enhanced data security. In embodiments, the architecture comprises two sub-systems, each with their own processing units and memories, and a defined set of interfaces that interconnect the two sub-systems and the external world. One sub-system is designed to provide a familiar environment for running computer applications. The other sub-system is designed to provide a secure bridge between the first sub-system and users via input and output devices.
