Storage Media, which is being decommissioned, will be passed to a specialist contractor for secure disposal.
A) Hard Disk Destruction
Degaussing is a simple method that permanently destroys all data and disables the drive. Degaussing uses a high-powered magnetic field that permanently destroys data on the platters. The recommended specification for data destruction is the SEAP 8500 Type II standard used for classified government material.
B) Solid-State Devices
Solid-state devices normally require the complete physical destruction of the device to ensure that any recovery of data is impossible. Incineration will melt SD cards. Devices such as USB thumb drives should be physically destroyed using brute force methods. As long as appropriate safety methods are in use, non-specialist staff can destroy these devices.
C) Cloud Based(AWS) Devices
“When AWS determines that media has reached the end of its useful life, or it experiences a hardware fault, AWS follows the techniques detailed in Department of Defense (DoD) 5220.22-M (“National Industrial Security Program Operating Manual”) or NIST SP 800-88 (“Guidelines for Media Sanitization”) to destroy data as part of the decommissioning process.” P.39 AWS Security Best Practices White paper
