What, then, are "independent application modules?" Lynx has analyzed these specifications and is able to discuss its product plans in this areas in more detail under NDA. All system management calls are logged in a protected security log buffer. For example, sometimes the intellectual property created in that work is something that they deem differentiated and worthy of owning. Developed and maintained in San Jose, California in accordance with FAA DO-178 Safety Quality Standards and DoD Risk Management Framework guidelines, LynxSecure is certified, fielded, and maintained on classified DoD networks. How could LYNX MOSA.ic be configured for a Line Replaceable Unit (LRU) application? There is significant overhead to add process management. Yes. As a result, only those portions of the OS that are necessary to support the application will be linked into the final executable binary, reducing the attack surface resulting in improved security properties. Additional details are available in the LynxSecure Architecture guide (product documentation). Both LynxSecure and LynxOS-178 rely on an external bootloader, and that is where secure boot needs to happen. How does shared memory IPC (Inter Process Communication) work between LYNX MOSA.ic guest operating systems? Multiple users require authorization and authentication, resource isolation, etc. Click here to learn more about what Lynx is doing with its partner ecosystem to reduce your technology and business risks, costs, and time to deployment. Software cache-coloring is not supported today. A system configuration can use partitions to restrict access to resources and interpretation, and global system capabilities. It is a static hypervisor that is configured on your host PC so that when it boots, it allocates target hw resources (cores, memory, peripherals) into fixed immutable virtual machines. Standard Linux Containers; Buildroot Linux is a full featured embedded Linux distribution that is part of MfA and capable of running the Docker Engine and Linux infrastructure necessary to host and run 3rd party created containers. Is Lynx actively working on multicore designs for systems requiring certifications? You can find some details in the case studies area of our website, We see customers using containers and infrastructure like Kubernetes to deliver software updates to deployed platforms. Lynx continues to work closely with Intel and is planning to support both x6000E (previously known as ElkHart Lake), Tiger Lake and other, as-yet-unannounced processors. are set to the values required for the hardware to enforce the defined partitioning scheme. PTP (Precision Time Protocol aka IEEE1588) shares time across the network. Flash, SSD, etc. VM0 is a privileged partition, think of it as the root partition, it can see into the other partitions. Yes! Notice the indication of virtual machine (VM) types: Application VM Guest environment primarily used to host applications. Each exec file has access to the POSIX API as well as the ARINC API. Munitions List (USML) (codified in U.S. 22 CFR 121.1). This approach enables our customers that value DO-178C certification to harness the existing artifacts that are being created for the work on the LynxOS-178 real time operating system. After a competition between the Boeing X-32 and the Lockheed Martin X-35, a final design was chosen based on the X-35. We want our customers to buy what they needand only what they need. The events can be filtered and actions defined should you wish to halt or reset a VM that generates event X. By reducing the number of complex software abstraction layers between your applications and chosen hardware, this burden is minimized and the resulting system is safer and more secure. Partition level authentication is achieved in the hypervisor through the monitoring of system management calls. Of simultaneous shared access to the screen is useless, the way this works is that LynxSecure provides a mechanism to switch which the screen between each VMs framebuffer. Yes we do. The LynxSecure binary executable file is a .srp (system resource package) file. Excellent written and verbal communication skills. What is Eclipse? Aerospace, defense, industrial, and critical infrastructure clients are increasingly focused on adopting open architecture software solutions that deliver reliable performance and security while decreasing development and sustainment costs.

Stanton What else can you share regarding security aspects of LynxSecure? Power-on First Stage or Primary Bootloader is in reference to the boards native, power-on firmware and bootloader for the system, i.e. In addition to cert documents and workflows that we are happy to provide upon request (and in addition to offering NIST 800-53 security artifacts), LynxSecure offers other specific security features: LynxSecure relies on an external bootloader, and that is where secure boot begins. In February 2019, Lynx announced LYNX MOSA.ic (pronounced mosaic). Position: Java Full stack Developer. Common Criteria defines security evaluation assurance levels (EALs) ranging from EAL1 (least secure) to EAL7 (most secure) to describe the security level achieved by Security Targets (components) being evaluated (tested) against a Protection Profile.For or a few years beginning in 2007, the Common Criteria included a profile for separation kernels called the Separation Kernel Protection Profile (SKPP) that real-time operating system (RTOS) providers such as Lynx, Wind River Systems, and Green Hills Software built products toward. Mike Barnes - Sr IT Engineer - Lynx Software Technologies - LinkedIn Our business model is that a block of services comes with the artifacts to train users how to tweak them for additional hardware. Once the SoC has an accurate PTP clock, PCI BAR sharing is used to give other VMs access the timer registers. Lynx does not guarantee the accuracy of the information herein beyond the date of publication. Some employees have been here for one year, others since the beginning! You change the start-up script to call your application instead of bash, leaving you with a system with just the minimal necessary components, and hence less expensive to certify. Lynx has also developed tests that analyze maximum stack usage that is used for stack analysis as well as test vectors that exercise boundary conditions on each functional module that is involved in certification. The software development process typically ensures that the static analysis tool can be run against the certifiable code base to create an assurance case for the software. Each exec file has access to the POSIX API as well as the ARINC API. It makes assumptions and chooses precisely which HPA (host physical) and GPA (guest physical) addresses to allocate the memory regions, the interrupts and the peripherals connected to each VM. The technology has also enabled programs to effortless spawn derivative platforms into adjacent programs further maximizing component reuse.

It owns the hardware resources and the applications are completely reliant on its correct operation. For Lynx: But, in general, LynxSecure does NOT contain any certified cryptographic libraries. Hybrid designs can be certified and supported with a heterogeneous, multi-core safety- and security-partitioning framework. It stipulates the following: Lynx products and services are not subject to ITAR. In this sense, there is nothing special about a partitionit is just a normal LynxOS-178 application (that is, a set of processes, threads, a filesystem and device nodes). San Francisco Bay Area, Silicon Valley), Operating Status of Organization e.g. The Common Criteria remains a useful standard, but no further SKPP evaluations will be accepted, and the SKPP is effectively dead. VM access to the CPUs built in Random number generator can be disabled to prevent it being used as a covert information channel. It allows the use of standard LynxSecure artifacts prepared by Lynx ahead of time for whatever choice of VM configuration the project chooses. Message: guests can use the kernel to send a 64 byte message to another guest in a single direction. Policy exceptions can come from guest generated hypercall events and hardware generated events E.g. My system must achieve safety and/or security certifications. It can be used temporarily during development, for example, to validate USB hardware is working before porting the driver to your RTOS environment. Lynx Simple Applications (bare-metal applications) currently have tool chain support based on GCC. LynxSecure is developed and maintained in San Jose, California in accordance with FAA DO-178 Safety Quality Standards and United States DoD Risk Management Framework guidelines. Luminosity offers a modern interface based on open standards, giving a consistent user experience across the Lynx Software Technologies family of real-time operating systems. Advanced features such as scheduling of VMs to share cores, and segmented boot (runtime replacement of VM images) require direct modification of the HCV. LynxOS-178 supports up to 16 ARINC 653 time, space, and resource partitions per OS instance. Policy violations can be programmed to trigger mode switching events to precisely recover from the event. All security policies, hardware partitioning, and inter-guest memory access privileges are defined according to the engineers needs, with few design impositions due to the hypervisor. Initial milestone benefits speed and delivery for platforms using advanced NXP Semiconductors Layerscape processors. Does LynxOS have any features for reporting security risks? LynxOS-178 is a commercial off-the-shelf (COTS) RTOS that fully satisfies the objectives of the DO-178B level A specification and meets requirements for Integrated Modular Avionics (IMA) developers. Our NIST security artifacts are for LynxSecure on x86. Individual applications can have dedicated encryption modules assigned to the edge of the application interface to decrypt data reads and encrypt all data writes before passing the data to the RTOS filesystem to complete persistent block device commits, Partition Layer Individual drive partitions can be separately encrypted by a software encryption layer that can transparently decrypt/encrypt data read and write requests performed by individual application partitions, Block Device Layer Full disk encryption is supported through the integration of SED (Self Encrypted Drive) with the Lynx RTOS hardware control interface. We use the RedHat package manager, a popular, open source package management utility. To learn more, visit the the "more information" page for LynxOS-178.
