Just as you are responsible for your own security while on a mission, or the security of your buddy, the security of the compound or barracks where you work, you are also responsible for the security of the communication that you do. You pay attention to what you say, to whom you say it. The data that is sent over the network must also be secure. Data theft is not just something that is physical, but something that happens remotely by breaking into your network. Network encryptors protect the network in any case.
