FTP via VPN:
o Good protection for the portion of the network actually
covered by the VPN
o No protection for portion not covered by the VPN (for example, if
using site-to-site VPN, traffic will not be protected in each
organization's internal networks)
o Need to setup VPN
SFTP
o Good protection for all traffic
o Need to have SFTP software (but available for free - www.openssh.org,
http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html)
FTP with PGP-encrypted files
o Protection not only for data in transit, but also at rest
o Non-repudiation based on digital signautres, which offer higher
legal protection than server logs
o Need to install/configure/program PGP software on both ends
