    What is the difference between simple and secure, certified data erasure?

    Some companies have the PC completely erased with the operating system in the form of formatting, which is often described as simple data erasure. However, this has nothing to do with data deletion, as the data can be restored using simple means. There is no certified data deletion in this sense, only the process of the deletion process during the data destruction can be certified, with the BSI data deletion there is the possibility to delete GDPR compliant. On the other hand, there is secure data deletion and describes the combination of the deletion algorithm, the process flow and the medium to be deleted. This also determines the duration of the deletion process.

    How is data carrier destruction defined in accordance with DIN EN 66399?

    DIN 66399-1 describes the general principles and terms of certified data destruction. Data carriers such as HDDs, SSDs, LTO tapes, CDs, smartphones or tablets are destroyed in accordance with DIN 66399-2 with security levels E4, T5, O4 and H5. The requirements for certified data carrier destruction are placed on the destruction machine. H5 describes the destruction of HDDs with a maximum shredder size of 320 mm² (10% tolerance up to 800 mm²). The destruction of data carriers from smartphones, tablets and SSDs is indicated with E4 - here the maximum shredder size is 30 mm² (10% tolerance up to 90 mm²). DIN 66399-3 describes the process of data destruction.

    Why secure data destruction?

    A simple data deletion is no longer sufficient these days to act responsibly with company and customer data in accordance with the GDPR. If data is lost or misused, there is a risk of high fines and criminal penalties. You should have your data deleted e.g. B. from a professional refurbisher. A written confirmation of the data deletion is essential. Security containers should also be used to protect your data media.

    What is the difference between "disposal" and "destruction" for data carriers?

    When they are disposed of, the data carriers usually end up undeleted on the landfill at the disposal company, where your data is freely accessible and not protected like a certified data deletion. If the hard drive is destroyed, the data carriers are mechanically destroyed with the help of a shredder and cannot be restored. The security level must be observed here. On-site disk destruction is a common practice to ensure that the disks do not leave your company in working order.
