QNX Software Development Platform
QNX SDP is a cross-compiling and debugging environment, including an IDE and command-line tools, for building binary images and programs for target boards running the QNX OS 8.0.
System Security Guide
The QNX System Security Guide is intended for both system integrators who are responsible for the security of a QNX OS system and developers who want to create a QNX OS resource manager free from vulnerabilities.

  - Security Features Overview
  - Security for Developers
  - Security for System Integrators
    - A security checklist for system integrators
    - Privilege control
    - Systems without passwords
    - Secure boot
      Secure boot is a mechanism that ensures the integrity of the running system, by cryptographically verifying each stage of the boot process.
    - Cryptography for system integrators
      QNX OS supports multiple ways to access cryptography services.
    - Address space layout randomization (ASLR)
      Address space layout randomization varies the location of data and instructions each time an executable is loaded as long as it was compiled with Position-Independent Executable (PIE) support.
    - Fortified system functions
      QNX OS fortified system functions are designed to detect out-of-bounds memory accesses by performing lightweight parameter validation at compile-time, runtime, or both.
    - Access control
      Access control is the selective restriction of access to a resource. Access controls take many different forms and the sections below describe which ones can be used in QNX OS systems.
    - Filesystem security
    - Random number generation
    - Virtualization security features
      Virtual devices (vdevs) provided by QNX Hypervisor for Safety (QHS) and other QNX hypervisors.
    - The /proc filesystem
    - Application groups
      Application groups are used to group processes together so they can be controlled as a group.
    - chroot (change root)
      The QNX OS chroot() function allows you to set the root directory of a process to a path other than the system's root directory, a feature common to most UNIX-like operating systems.
    - Hypervisor security
      The QNX hypervisor is built as an extension of the QNX OS microkernel. As such, it inherits the security features of the microkernel itself as well as the secure execution environment created by the microkernel. In addition, the hypervisor has additional layers that are purpose-built for secure virtual machine operation.
  - Abilities
  - Security Policies
    Although QNX OS allows a process to set which operations it is permitted to do, a better option is to use the system’s security policies functionality.
  - Fortified System Functions
  - Pathtrust
    The pathtrust feature prevents processes from executing untrusted code. If a process is compromised, pathtrust mitigates the threat of the system being further compromised by an attacker using chained-together exploits.

QNX Software in the Cloud
QNX Software in the Cloud enables developers to use the QNX software in Amazon Web Services (AWS) and Microsoft Azure (Azure).
QNX Toolkit for Visual Studio Code
This User's Guide describes the QNX^® Toolkit for Visual Studio Code. The guide introduces you to the QNX Toolkit by explaining the QNX development environment and how to build, run, and debug your QNX^® Operating System (OS) applications and systems.
QNX Hypervisor and QNX Hypervisor for Safety
The QNX Hypervisor and QNX Hypervisor for Safety products allow you to run multiple OSs on a target system so you can separate critical and non-critical functions, support a wide variety of applications, and reduce hardware costs.
Typographical Conventions, Support, and Licensing
This section describes the typographical conventions used throughout the documentation, explains how to obtain technical support, and provides some information about licensing.

This section discusses the security features that you should use when you are creating a QNX OS system using pre-built applications.

For information on the security features that you use when creating the pre-built applications, see the Security for Developers chapter.
