An organization must distribute a highly sensitive application that requires stringent validation of its integrity before installation. The application is large, and the distribution speed is a secondary concern. What is the BEST distribution method to ensure the integrity of the application while adhering to the security policy?
A file download via an unencrypted File Transfer Protocol (FTP) connection
Encrypted physical media such as DVDs with integrity checks
A web-based file hosting service with password-protected downloads
Peer-to-peer file sharing within the local network
Downloadable content from a public cloud service with standard HTTPS encryption
An email attachment sent through an encrypted email service
Distributing the application through encrypted physical media is the best method in this scenario to ensure the integrity and security of the application. While downloadable content is convenient, it is more vulnerable to interception and tampering during transmission. Encrypted physical media helps guarantee that the application has not been tampered with, as the recipient can verify the integrity of the encryption upon receipt. This method is secure and suitable for scenarios where the size of the application is large, and distribution speed is not the primary concern.
