What is Data Destruction?
The three main ways to ensure that the data is no longer accessible on the storage media are:
It is the process of overwriting old information with new data that makes it difficult to locate or recover.
It is the process of eliminating magnetic field and destroying the storage device at the same time that makes it impossible to recover any information.
The physical destruction which includes disk shredding, disk crushing or disk melting.
These solutions all have their advantages and disadvantages and choosing one over the other depends on the level of destruction required; and whether the data destruction has to be certified for compliance purposes.
There are a number of situations where data needs to be properly destroyed when:
- Changing service providers
- Migrating from an on-premise infrastructure to the cloud
- Stopping a service or a product.
- Upgrading, decommissioning or scrapping IT equipment.
What are the risks of Undestroyed Data?
Why does your company need Certified Data Destruction?
Under new data protection laws, businesses are no longer allowed to store old data that is no longer needed and are responsible for destroying sensitive data. Thus, having a consistent data destruction policy followed by everyone within your company at all times is vital.
The first important part of a data destruction policy is the classification of the information – whether it is confidential trade information or customers’ private information or other documents that have no value – and which type of data can be removed. You can also decide which level of destruction is appropriate for your company’s situation and whether it requires a certification in order to be compliant.
