Device Updates: Security Shield

By default, the Pulsar system is configured to use the Wind River public repository for the most critical Linux updates.

Wind River also offers an update service providing a full range of bug and security fixes for Pulsar – Pulsar Security Shield. These updates can include fixes for common vulnerabilities and exposures (CVEs), unreported vulnerabilities, and product bugs that do not have security implications.
