These flashcards cover key terms and definitions related to the decommissioning of network devices and data sanitization processes.

Decommissioning Phase

The phase in a system's lifecycle when a device is disposed of, posing risks related to data security and software licensing.

Data Remnant Removal

The process of ensuring that no data can be recovered from storage devices before disposal or reuse.

Factory Reset Routine
