For more information, see the Amazon Elastic File System product page. You can use an EFS file system as a common data source for workloads and applications running on multiple instances. Manages the files encryption and decryption for the Encrypted File System (EFS). Login is protected by a rather strong password, but this doesn't stop anyone from pulling out the disks and making a copy. Amazon EFS provides scalable file storage for use with Amazon EC2. sudo yum install -y amazon-efs-utils Next steps After installing amazon-efs-utils on your EC2 instance, proceed to the next steps for mounting your file system: Install botocore so that you can use Amazon CloudWatch to monitor your file system's mount status. Solution Now you can apply the EFS certificate generated for the SYSTEM account to an existing EFS-ecrypted file or folder. Users that are utilizing EFS can share encrypted files with other users. The server is running some services which receive data from devices and store them around, and it has a web app for visualization. Run the following command to install the amazon-efs-utils package. EFS in Windows Server 2003 further improves on the capabilities of EFS in Windows 2000. To clarify, we have a server located at a remote location, and we would like to protect our installed software from copying or disassembly. If this option is chosen, all the other options will be ignored. The reason I am asking is that I would like to enable encryption on a certain folder containing deployed executables for several applications (a service, a gui console, some command line tools, etc.), so I'd like to understand exactly how I will need to configure all this to work. Command line options /K Creates a new certificate and key for use with EFS. how are Windows services able to use the disk at all in this case? How does this work if you enable encryption for the entire drive? I.e. k Create a new certificate and key for use with Encrypting File System (EFS) files. If I enable encryption for a certain folder, I presume this means that other system accounts (like LocalSystem or NetworkService) won't be able to access contents of this folder. Update the files to use a new EFS key: CIPHER /rekey pathname. EFS encrypts data with a one-time pseudorandom key, called the File Encryption Key (FEK), and then it encrypts the FEK with the users current EFS public key. As of June 2001, Microsoft has developed an improved version of the Cipher.exe tool that provides the ability to permanently overwrite (or 'wipe') all of the deleted data on a hard disk. If I understood correctly, when I enable NTFS encryption (EFS) for a specific folder in Windows, it uses specific account's user name/password (salted) to create asymmetric keys for data encryption and decryption. Cipher.exe is a command-line tool (included with Windows 2000) that you can use to manage encrypted data by using the Encrypting File System (EFS).
