# Encrypt all inter-system communication

Any communication that the PingDirectory server itself has with other systems should be encrypted to resist observation and interception.

This also applies to any communication that the underlying system needs to perform, including name service resolution, use of network-based filesystems, remote logging, shell access, and file transfer.
