Security must be a top priority for devices that support critical processes.
Industrial control systems, medical devices, automotive systems and many other embedded systems must be secure. These devices need to be protected from exploits that can compromise system integrity, performance, system availability and the confidentiality of sensitive data.

A classic security breach vector involves exploiting weak authentication. As security researchers like to point out, failing to change default passwords for administrative access remains the top security issue for all types of IT systems.
But a related — and perhaps more devious — attack vector involves exploiting a weakness in a process that is supposed to help ensure device security in the first place: the remote system update.
