A practitioner wants to move data from a target system and reduce the chance of it being read by unauthorized observers. The data is planning to be archived for smaller size and moved offsite. Which method fortifies protection against anyone trying to monitor the transfer?
Split the files into smaller archives and rely on built-in operating system permissions
Add the files into an archive and encrypt them with a strong cipher
Compress the files in an archive and rename them with different extensions
Use Base64 on the files before packing them into an archive
Using a password-protected archive with a robust cryptographic algorithm prevents anyone who intercepts the data from reading it and minimizes space usage by compressing the files. Renaming files or splitting them does not offer sufficient cryptographic security. Base64 also does not secure the data from viewing. Directory permissions do not encrypt the data in transit.
