Tokens Improve IoT Security

Even though malware may be sand-boxed in an isolated partition, it can still attack system objects. Despite isolated partitioning, a hacker might determine a valid RTOS object address and operate on it.

Task Runtime Limits

A common attack vector for IoT and embedded devices is to put a task into an infinite loop. This blocks all equal and lower-priority tasks from running. This article looks into how this kind of attack can be prevented.

Portals Isolate Partitions

Portals provide an indirect API to isolate services in one partition from callers in other partitions.

ptasks and utasks Improve Security

Two kinds of tasks, two levels of protection — and a four-step, partition-by-partition process for moving vulnerable legacy code out of privileged mode into unprivileged mode.
