Embedded devices have become more interconnected and reliant on commoditized hardware running commercial or open operating systems. While this has provided greater flexibility for software selection, faster time to market, and mid-cycle adoption of new technologies, it has also made systems vulnerable to malicious software installations and unauthorized changes as they flow through a multi-party distribution channel. Additionally, these remote systems are often difficult to patch with critical software updates, leaving them vulnerable to both existing and zero-day threats. Change control provides update-free control over what software can run, ensuring continuous system uptime and integrity. This eliminates emergency patching and the need to run performance-draining anti-virus software.
