7.14 Secure Disposal or Re-Use of Equipment

Items of equipment containing storage media should be verified to ensure that any sensitive data and licensed software has been removed or securely overwritten prior to disposal or re-use.

Secure disposal or re-use of equipment in information security refers to the process of safely disposing of or reusing computer hardware and other equipment in a manner that protects the confidentiality, integrity, and availability of the data stored on the equipment. This can include tasks such as securely wiping the data from the equipment, physically destroying the hardware to prevent it from being reused, and properly disposing of the equipment to prevent environmental harm. The goal of secure disposal or re-use of equipment is to prevent the unauthorised access or misuse of data that could compromise the security of the network.

There are several standard guidelines for the secure disposal or re-use of equipment in information security. Some of these guidelines include:

• Documentation: It is important to keep records of the disposal or re-use of equipment, including details such as the date and method of disposal, the person responsible for the disposal, and any other relevant information. This documentation can be used to demonstrate compliance with security policies and regulations and can help ensure that the disposal or re-use of equipment is done in a secure and responsible manner.
• Data erasure: Before disposing of or reusing equipment, it is important to securely erase the data stored on the equipment. This can be done using specialized software tools that overwrite the data on the equipment multiple times, making it impossible to recover the data.
• Physical destruction: In some cases, it may be necessary to physically destroy the equipment to prevent it from being reused. This can include tasks such as shredding hard drives, crushing disks, and smashing other hardware components.
• Proper disposal: It is important to properly dispose of the equipment to prevent environmental harm. This can include recycling or donating the equipment, if possible, or disposing of it in accordance with local laws and regulations.
