Green Hills Software, Inc. has announced the availability of three new high assurance software components for its INTEGRITY®-178B real-time operating system (RTOS): an RTCA/DO-178B Level A-compliant Partitioning Journaling File System called PJFS-178B, an RTCA/DO-178B Level A-compliant network stack, called IPFLITE, and an ARINC 615A dataloader.
The Journaling File System provides multiple INTEGRITY-178B partitions with concurrent power-fail safe access to an underlying file system. IPFLITE’s client/server architecture allows multiple applications to access the underlying network stack that resides in a virtual INTEGRITY-178B partition.
PJFS-178B, IPFLITE and the ARINC 615A dataloader are available as optional components for Green Hills Software’s INTEGRITY-178B operating system.
This announcement also follows the U.S. Government’s recent announcement that INTEGRITY-178B has been certified to the highest security assurance level required by the U.S. Government for operating systems — EAL6+/High Robustness.
This EAL6+ certification is the first of its kind, the highest Common Criteria security level ever achieved for an operating system. Only an EAL6+ High Robustness operating system is certified to protect classified information and other high value resources from attack by hostile and well-funded attackers. This is secure by anyone’s definition.
The highest security standard to which any other operating system is certified only protects against "inadvertent or casual attempts to breach the system security." That is not even close to secure by anyone’s definition.
With the new PJFS-178B file system, IPFLITE network stack and ARINC 615A dataloader, Green Hills Software now offers system developers and integrators a single-source solution for their high assurance operating system and related software components without relying on third party software products or certification services.
