![]() ![]() Premier Healthcare: PII of 20,000 patients got leaked when an employee’s laptop was stolen in 2016.Patient’s names, medical record numbers and ethnicities got compromised. Lifespan: In Feb 2017, an employee’s MacBook was stolen, as a result, the PII of around 20,000 patients got leaked.The following organizations did not have disk encryption enabled and suffered data a breach due to a lost or stolen device: File-level encryption (FLE) - FLE is file system level based encryption, it encrypts the data in individual files and directories.Full disk encryption (FDE) - As the name says, FDE protects the entire volume and encrypts each and every file present on the system.Hence, someone having access to the computer/laptop cannot read the data stored on the disk, thus the organization does not have to worry about data breaches due to lost or stolen devices.įull disk encryption and file-level encryption are the two types of encryption available for encrypting data: In full-disk encryption, each and every file stored on the operating system is encrypted using the encryption key. In disk encryption, the whole data is encrypted and decrypted using the same key, thus it makes use of symmetric encryption. If the encryption process uses the same key to encrypt and decrypt the data, it’s called symmetric encryption and if the keys are different then it's called asymmetric encryption. The encryption process makes use of symmetric and asymmetric encryption for encryption and decryption of data. Using modern encryption algorithms, it is not easy or feasible to decrypt encrypted data, thus a breach of encrypted data is not considered reportable by many regulatory authorities. Encrypted text hides the original data from unauthorized users since encrypted text cannot be read by anyone. Encryption is the process of converting plaintext to encrypted text.
