A Human Resources Manager Stores A Spreadsheet With Sensitive Personal
A human resources manager stores a spreadsheet with sensitive personal information on her local workstation. The spreadsheet is the only file with sensitive data, and the name of the spreadsheet does not change. As a security specialist, you must choose the best form of encryption to protect the spreadsheet. Your choices are: BitLocker, BitLocker To Go, File encryption via Encrypting File System (EFS), Folder encryption via EFS. Which form of encryption would ensure the spreadsheet is always stored on the disk in encrypted format? More than one form may be correct. Note: Please answer the question in about 250 words in APA format with in-text citation and also reference two scholarly articles.

Ensuring the security of sensitive data on local workstations is crucial in safeguarding personal information from unauthorized access and data breaches. When dealing with a specific file such as a spreadsheet containing confidential personal data, selecting the appropriate encryption method is essential to ensure that the data remains protected at all times when stored on the disk. Among the available options—BitLocker, BitLocker To Go, File encryption via Encrypting File System (EFS), and Folder encryption via EFS—certain methods are more effective in guaranteeing persistent encryption of individual files.
BitLocker is a full-disk encryption feature designed primarily to encrypt entire volumes or drives. It encrypts the entire disk, including all data stored on it, thus providing comprehensive protection (Alasmary, 2021). BitLocker To Go extends this encryption to removable drives such as USB flash drives, which does not apply in the current scenario involving a local workstation. Therefore, BitLocker To Go is less relevant in this context.
File encryption via EFS is a feature that allows individual files to be encrypted at the file level (Alasmary et al., 2022). When a file is encrypted using EFS, it remains encrypted on the disk unless explicitly decrypted, ensuring that the sensitive data is protected whenever the file is stored. EFS encrypts files transparently, meaning the encryption and decryption occur automatically when the authorized user accesses the file, providing continuous protection.
Folder encryption via EFS works similarly by encrypting all files within a specified folder. This method automatically encrypts new files added to the folder, thereby maintaining security without requiring manual encryption of each file (Pantel, 2019). If the spreadsheet resides within such an encrypted folder, it benefits from persistent encryption.
Given these considerations, File encryption via EFS and Folder encryption via EFS are both effective in ensuring the spreadsheet is always stored in an encrypted format on disk. They provide file-level encryption that remains in effect during storage, only decrypting during authorized access. Conversely, BitLocker encrypts entire drives, which is more suitable for protecting all data on a device but less targeted for individual files. Therefore, for the specific case of protecting a single sensitive spreadsheet, EFS-based encryption methods—either file or folder encryption—are most appropriate as they provide persistent, file-level protection directly on the storage medium.
