What is the meaning of data erasure?
Data erasure (sometimes referred to as data clearing, data wiping, or data destruction) is a software-based method of overwriting the data that aims to completely destroy all electronic data residing on a hard disk drive or other digital media by using zeros and ones to overwrite data onto all sectors of the device.
How is data destruction different than deletion?
Whereas anyone can delete data, it takes a skilled professional to actually destroy data. The goal of data destruction is to completely get rid of any trace of the data so that it is no longer accessible.
What are data erasure standards called?
In the past few years, NIST Special Publication 800-88 has become the go-to data erasure standard in the United States. Originally issued in 2006 and revised in December 2014, this publication addresses flash-based storage and mobile devices, which weren’t considered under the DoD process.
What is a data deletion request?
A Personal Data Deletion Request is a document through which someone can request that their personal data be deleted from a company, whether that company is online or not. Personal data includes things like legal name, email, financial information, and more.
Why is data erasure important?
By overwriting the data on the storage device, the data is rendered unrecoverable and achieves data sanitisation. With data erasure, the data storage device can still be used.
What is data deletion and recovery?
Data recovery is the process of restoring data that has been lost, accidentally deleted, corrupted or made inaccessible. In enterprise IT, data recovery typically refers to the restoration of data to a desktop, laptop, server or external storage system from a backup.
Why is data deletion important?
The most important reason for data destruction is to keep your files and folders that were stored on your device from falling into the wrong hands. Even if you think that your erasure software had been successful, simply throwing out your electronic device is a gamble.
Why bit erasing is needed?
BitRaser helps safeguard privacy and prevents data leakage when disposing, donating, returning or reselling old storage media or devices. For organizations, it is a perfect tool to mitigate risks of data leakage and meet statutory & regulatory compliance.
When should you delete data?
Benefits of reducing data volumes Once the data has stretched beyond data-retention requirements, it’s time for it to be deleted. This might be because it has been archived for the amount of time required by law, or because it has been stored indefinitely, but has not been looked at for months or years.
