Final answer:
The statement is true, as embedded systems are often limited by power, computational ability, and network capabilities, all of which can impact their security.
Step-by-step explanation:
The statement that power, compute, and network are all security constraints for embedded systems and specialized devices is true. Embedded systems, due to their specialized and often resource-constrained nature, must be carefully designed with security in mind. Power constraints can affect a device's ability to perform security functions, compute constraints can limit the complexity of security algorithms, and network constraints can restrict how often and how securely an embedded system can communicate with other systems. Ensuring security within these constraints requires a tailored approach that takes all of these factors into account.
