What is ISO 27001 data destruction?

ISO 27001 data destruction provides guidelines for properly managing information security posts. The standard ensures that sensitive data is permanently and securely removed from unwanted media. 

Guidelines for secure disposal and destruction of information assets

If you want to have strong data security, you must ensure you dispose of them properly when they are no longer in use. For this, you have a few secure options at your disposal:

• Overwriting data with random patterns or zeroes
• Physically destroying storage media
• Degausser to wipe data from media

What should you include in the disposal and destruction policy?

Scope definition

Start by defining the policy’s scope. This step helps you figure out what’s covered and what’s not. Think about:

• The types of data covered
• The locations where this data is stored
• Who has access to this data

Records for disposal and destruction

This policy ensures you’re on top of proper record disposal and destruction. It applies to all types of records, regardless of format, that are no longer needed for business purposes. Keep it up to date.

Asset register

Asset registers play a significant role. When an asset has no value anymore, it can be disposed of or destroyed. But remember to remove it from the register first. This ensures clarity within the organization.

Asset disposal form

ISO 27001 standards emphasize a formal disposal process, especially for sensitive data. The asset disposal form is key in tracking which assets are disposed of and when. It helps with both physical and digital assets.

Responsibilities

Once you know what needs to go, decide who’s responsible for the task. It could be a specific individual or a department. Having clarity on this ensures the job is done right and on time.

Appropriate disposal method

Now, choose the right disposal method. There are many options out there, so select one that fits your needs, budget and the type/quantity of waste you have.

Verification

You must have a way to verify data removal after a specialized company or contractor handles the media. Keeping things organized and audited is key. Even tracking hard disk serial numbers is the minimum for this process.
