* End-to-end encryption of all inbound and outbound communication, including personal email and chat sessions that allow solders to securely communicate with families

* Layer 7 inspection and TCP/UDP port restriction, including firewall rules to only allow TCP port 80 and 443 and approved applications

* A host-based whitelist of approved websites and applications that only allow mission-related tools and sites

* The use of satellite communication to include multiple proxy servers to scramble the source IP address

Which of the following is of MOST concern in this scenario?
