Communications security and techniques are the best area for addressing this objective.
"Information security management and techniques" is incorrect. While the overall information security program would include this objective, communications security is the more specific and better answer.
"Client security management and techniques" is incorrect. While client security plays a part in this overall objective, communications security is the more specific and better answer.
"Server security management and techniques" is incorrect. While server security plays a part in this overall objective, communications security is the more specific and better answer.
