You do not need to configure a certificate authority on your network to use EFS.
<em>EFS</em> is the short form for<em> Encryption File System</em>. With EFS, users can encrypt their files and folders and even the entire content of a given drive. By encrypting these files and folders, the access to them are restricted and thus increasing, improving and enhancing the security level of the users' data.
In other words, even though there are other ways to restrict access (such as using <em>logon authentication</em> and <em>NTFS file permissions</em>), EFS allows to add another layer of security to data.
To <em>encrypt</em> and <em>decrypt</em> data files and folders in EFS, a <em>certificate authority (CA)</em> could be used. This is however not a requirement. In the case where there is no certificate authority, EFS will sign a default certificate that will be used for encryption. In other words, <em>EFS will generate its own certificate</em> if none does not exist.
<em>The following are other things to note about EFS</em>
i. EFS uses a public and private key pair to encrypt data.
ii. Users do not need to enable EFS. It is enabled by default.
iii. For EFS to encrypt a file, the NTFS file system must be used.
Since a certificate authority is not required on your network to use EFS, the correct option is:
(b) False.
