The "potential security implications" are referring to the fact that someone could set these remotely without authentication. So, yes, setting up SSL for HTCondor would do the trick.
1) Install SSL certs (and the CA/signing cert) on the central manager and execute nodes.
2) Set the AUTH_SSL_CLIENT_* and AUTH_SSL_SERVER_* condor_config entries.
3) Add SSL to your list of authentication methods for "CONFIG"-level commands.
We have a recipe for setting up SSL for DAEMON-level (and NEGOTIATOR-level) commands, which you might find handy:
However, we don't yet have one specifically for using the client tools to issue commands to daemons (such as condor_config_val -rset).
If you become stuck at all, please let me know and I can spend a little time putting together a real recipe.
