Drives with this capability are known as self-encrypting drives SEDs ; they are present on most modern enterprise-level laptops and are increasingly used in the enterprise to protect the data. Theft of an SED results in a physical asset loss, but the stored data is inaccessible without the decryption key that is not stored on a SED, assuming there are no effective attacks against AES or its implementation in the drive hardware. Importance[ edit ] Information technology assets commonly hold large volumes of confidential data. Social security numbers , credit card numbers, bank details, medical history and classified information are often stored on computer hard drives or servers. Data breach[ edit ] Increased storage of sensitive data, combined with rapid technological change and the shorter lifespan of IT assets, has driven the need for permanent data erasure of electronic devices as they are retired or refurbished. Also, compromised networks and laptop theft and loss, as well as that of other portable media, are increasingly common sources of data breaches.
