precaution to harden your server and ideally place the RRAS server in your DMZ behind
hardware firewalls to minimize exposure.

Communication security is achieved only when the intended recipient(s) receive
and read the intended communication. In the physical world, this could mean
whispering into someone??™s ear or holding a closed-door meeting. This physical
closeness minimizes the risk of private messages being intercepted in transit. If you need
to communicate securely over larger distances, you can use a courier to transport your
message, or you can use the digital age equivalent: e-mail. The problem, however, is that
you have no real control over who reads that message while it??™s en route. Messages can
easily be intercepted and read. The solution is to perform some kind of encryption on
the message so that even if it??™s intercepted, the message cannot be read unless it can first
be deciphered.
Encryption can be performed in many ways. The easiest way is to transform the
message to be sent using some kind of key, and then, using the same key, to reverse the
process on the recipient??™s end to decode the information.
