Green Hills intros INTEGRITY PC.Green Hills Software, Inc., the market leader in safety-critical and royalty-free RealTime Operating Systems (RTOS (1) (RealTime Operating System) An operating system designed for use in a real time computer system. See real time system, embedded system, process control and OS-9. ), have announced the immediate availability of INTEGRITY PC, an extension to the company's INTEGRITY operating system operating system (OS) Software that controls the operation of a computer, directs the input and output of data, keeps track of files, and controls the processing of computer programs. that enables the incorporation of legacy applications and traditional operating systems Operating systems can be categorized by technology, ownership, licensing, working state, usage, and by many other characteristics. In practice, many of these groupings may overlap. , such as Linux, into high-security and high-reliability applications. Boeing is using INTEGRITY PC in several of its military development programs. INTEGRITY PC has enabled Boeing to take advantage of existing Linux-based software, freeing it from having to port Linux code to a secure operating system The term "secure operating system" is a misnomer. Relevant articles include:
INTEGRITY PC integrates the INTEGRITY RTOS with Green Hills Software's new Padded Cell padded cell - Where you put lusers so they can't hurt anything. A program that limits a luser to a carefully restricted subset of the capabilities of the host system (for example, the "rsh" utility on USG Unix). secure virtualization technology See VT. See also virtualization. . The Padded Cell technology implements a "virtual computer" in a user-mode application running on top of the INTEGRITY operating system. Multiple Padded Cell applications can run concurrently on a single physical computer, each hosting its own guest operating system. An impenetrable wall around each virtual computer 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. "Like a padded cell, INTEGRITY PC prevents Linux, non-memory-protected operating systems such as Wind River's legacy VxWorks, and other insecure and unreliable software from harming the rest of a system while also limiting the harm it can do to itself," explained Dan O'Dowd Dan O'Dowd has served as the General Manager of the Colorado Rockies since September 20, 1999. Before being hired by the Rockies he spent 15 years working for the Baltimore Orioles and Cleveland Indians, working his way from Accounts Manager to Director of Baseball Operations / , founder and chief executive officer of Green Hills Software. "For years, the INTEGRITY operating system has lead the market for security-critical and safety-critical applications, including leading-edge avionics and defense applications. Now, with INTEGRITY PC, users of enterprise operating systems can upgrade to a secure foundation without having to re-implement their 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." |
