Secure RTOS puts Windows
in a padded cell

Green Hills Software has added several extensions to its Integrity PC Padded Cell secure virtualisation technology

Green Hills Software has added several extensions to its Integrity PC Padded Cell secure virtualisation technology that enables the incorporation of insecure and legacy software into high-security and high-reliability systems. These include support for Intel architecture (Pentium) processors and commercial off-the-shelf (COTS) PC systems, in addition to PowerPC processor-based computers that were supported previously: support for Windows XP as a guest operating system, in addition to Linux; and Linux binary compatibility, allowing Linux applications to be run without the need for a Linux guest operating system.

Built on Green Hills Software's secure Integrity operating system, Integrity PC significantly reduces the time and cost required to deploy secure systems.

It lets users and developers of high-security and high-reliability systems incorporate legacy applications and operating systems-including Windows and Linux-that do not otherwise satisfy a system's security, reliability, and assurance requirements.

Integrity PC also supports multiple concurrent instances of the same guest operating system, each isolated in its own protected partition, allowing legacy applications running at different security levels to share the same computer.

Integrity PC lets legacy applications safely share a computer with secure, native Integrity and Posix applications.

'With Integrity PC, legacy applications - even those running at different security levels or in different security compartments - can now be integrated with one another and with the most modern, high reliability and high security applications on a single COTS workstation, with assured separation and information flow control', explained Dan O'Dowd, founder and Chief Executive Office of Green Hills Software.

'Users can create secure systems from legacy components without having to re-implement or even recompile existing applications'.

'Legacy operating systems and applications can safely co-exist with totally reliable and security-critical applications running natively under the Integrity operating system'.

Integrity PC adds Padded Cell secure virtualisation software to the Integrity operating system.

Padded Cell software implements a 'virtual computer' in user-mode Integrity partition.

Multiple Padded Cell applications can run concurrently on a single physical computer, each hosting its own guest operating system and that operating system's applications.

An impenetrable wall around each partition ensures that errant, insecure, or malicious code can never compromise the security or reliability of the rest of the system - either inadvertently or via a hostile attack.

The new Integrity PC capabilities include support for COTS PCs based on Intel architecture (Pentium) processors - allowing Integrity PC to be used for they deployment of secure workstations, thin clients and servers based on inexpensive hardware.

Support for Windows XP as a guest operating system allows Windows and Windows applications to be deployed safely and securely in both enterprise and embedded applications, such as automotive infotainment systems, consumer electronics, defence electronics, industrial control systems, and medical devices.

Linux binary compatibility allows applications compiled for Red Hat Linux to run in a protected, Padded Cell partition without the need for a Linux guest operating system, saving the megabytes of memory required by Linux and also increasing performance.

Integrity PC with support for PowerPC processors and Linux as a guest operating system are available today.

Initial support for COTS PCs, Windows as a guest operating system, and Linux binary compatibility will be available in the second quarter of 2005. Request a free brochure from Green Hills Software....
