QNX OS for Security
The QNX® OS for Security delivers the OS that aerospace, defense and security systems need to meet the stringent security requirements of mission-critical applications.
In addition to the field-proven reliability of the standard QNX Neutrino RTOS, the QNX OS for Security provides different privilege levels for different applications, mediation to verify all accesses, and a mechanism for resource protection.
QNX OS for Security provides protective barriers between processes including networking and filesystems, which are typically within the kernel memory space in monolithic operating systems.
The QNX OS for Security is certified to Common Criteria ISO/IEC 15408 Evaluation Assurance Level (EAL) 4+. It is a full-featured RTOS that:
- Is certified under the common criteria standard
- Includes symmetric multi-processing (SMP) support for multi-core processors
- Includes the unique QNX adaptive partitioning technology in the certification
The microkernel architecture provides proper isolation between all aspects of a system, including filesystems and networking stacks.
The OS’s unique adaptive partitioning technology guarantees system resources for applications, while preventing rogue software from denying resources to other parts of the system. During overload conditions, this same technology enforces hard resource guarantees, ensuring that applications receive their budgeted share of resources.
