QNX Software Systems


Security as a Core Competency of QNX Neutrino

Well designed. Well tested. Well protected. That, in a nutshell, explains why the QNX Neutrino microkernel offers a level of security and fault tolerance unmatched by conventional operating systems. In fact, the key principles of secure software design - such as least privilege, complete mediation, economy of mechanism, and separation of duties - define the very essence of QNX Neutrino's microkernel architecture.

In this paper, security expert Eugen Bacic explores the tenets of software security and explains how QNX Neutrino provides an environment that is secure, stable, and reliable.

Learn how the QNX Neutrino microkernel offers:
  • mechanisms that prohibit unwarranted access to system resources
  • a concise, modular architecture that eliminates potential security holes
  • a tamper-resistant kernel that thwarts hacker modifications
  • mechanisms that prevent unintentional sharing of information
  • a strict prioritization scheme that ensures high-priority requests always execute first
  • audit facilities that address evolving requirements for accountability and privacy
