Organisations must have a disposal and destruction policy covering all data and assets, including electronic and paper records. The policy should specify the methods that will be used for disposal and destruction, as well as the criteria for determining when data and assets should be disposed of. Regular reviews and revisions of the policy are required. This blog post aims to outline the ISO27001 requirements for the disposal and destruction of data and assets. This is an essential topic for any organisation that must comply with ISO27001, as it covers the requirements for ensuring that data and assets are properly disposed of when they are no longer needed.
Common methods used in disposal and destruction
The following are the several ways to destroy confidential information:
- Shredding is a popular method of destroying confidential information because it is quick and easy. However, it is essential to note that shredding does not eliminate the information. The shredded paper can still be pieced together, which means that someone with enough patience could potentially reconstruct the data.
- Burning is another popular method of destroying confidential information. Burning destroys the paper's physical structure, making it much more challenging to reconstruct the data. However, burning also releases harmful chemicals into the air, which can harm nearby people and animals.
- Pulping is a process that breaks down the paper into small pieces using water and chemicals. This process usually takes place at a paper recycling facility. Once the document has been pulped, it is challenging to reconstruct the original document.
ISO27001 guidelines to dispose and destruction of information assets
When it comes to the disposal and destruction of data, organisations must ensure that they comply with ISO27001. This standard provides guidelines for managing information security, including the removal and destruction of data. This blog post will explore the guidelines set forth by ISO27001 and how organisations can ensure that they comply. The ISO27001 standard provides guidelines for the management of information security. This includes the disposal and destruction of data. The standard states that data should be erased when it is no longer needed and cannot be recovered.
- Organisations must ensure that data is securely erased when it is no longer needed. There are a number of ways to erase data, including securely
- erasing the data and replacing it with random or zeroes
- Physical destruction of the storage media
- Using a degausser to destroy the data on the storage media
- When erasing data, organisations must ensure that the method used is appropriate for the type of storage media being used. For example, overwriting data on a hard drive is not effective at destroying the data if the drive is repaired or replaced. In this case, physical destruction of the drive is necessary.
- Identify your data disposal and destruction requirements. These requirements will vary depending on your data type and how sensitive it is. For example, you may require that all confidential data be shredded or destroyed before it is disposed of.
What should be included in ISO27001 Disposal and destruction policy
- The first step in creating a disposal and destruction policy is to define the scope. This step will help you determine which data is covered by the policy and which is not. It would help if you also considered the following when defining the scope of your policy:
- The type of data covered by the policy.
- The locations where the data is stored.
- the individuals who can access to the data.
- Records for disposal and destruction- The Records for Disposal and Destruction Policy is designed to guide the appropriate disposal or destruction of records. This policy applies to all records, regardless of format, that is no longer needed for business purposes and are ready for disposal.
- Asset register- Asset registers are an important part of disposal and destruction policies. When an asset no longer has any value to the organisation or individual, it can be disposed of or destroyed. However, the asset must be removed from the asset register before doing so. This ensures that the organisation or individual. An organisation's disposal and destruction policy must decide to dispose of or destroy an asset. The policy must be approved by the board of directors and reviewed regularly.
- Asset disposal form- The ISO27001 standard requires organisations to have a formal disposal process. This includes ensuring that all sensitive data is erased from devices before being disposed of. The asset disposal form is a vital part of this process, as it allows organisations to track which assets have been disposed of and when. It can be used to track physical and digital assets, including fields for the asset type, asset ID, disposal date, and disposer name.
- Responsibilities- Once you have defined what needs to be disposed of, you need to determine who is responsible for performing the disposal and destruction. This may be a specific individual or department within your organisation. Identifying who is responsible for this task is essential to ensure that it is performed correctly and promptly.
- Mention an appropriate disposal method- After you have determined what needs to be disposed of and who is responsible for performing the task, you need to select a proper disposal method. There are many different methods available, and the best method for you will likely depend on the type and amount of waste you need to dispose of and your budget.
- Verification- There should be a process for verifying data removal after a specialised company or contractor has processed the media. Maintaining an efficient technique for controlling the data destruction process is crucial. This makes sure that all media that needs to be cleaned up or destroyed is properly audited and sorted. The bare minimum for tracking individual components should be tracking hard disc serial numbers.
