+# Network Security
+
+Two companies A, located in Canada, and B, located in France, want to collaborate on a super secret project. Each company has its own internal network with private servers and they want to allow the employees from the other company to access them.
+
+These two companies have hired you as a consultant to help them to enable their collaboration wile keeping their project secret. They are giving you a list of concerns: 
+
+- if the network is opened to the "outside", anybody could connect to their servers? Is there any way to prevent that? 
+- someone outside of their network might be able to eavesdrop or hijack their communication?
+- people might suspect that the two are working on super secret project if they see the type of communication they have?
+
+For each concern, they are asking you to:
+
+1. explain whether it is a valid concern by explaining them how they could be attacked or not
+2. help them secure their networks by providing the best and the most straightforward solution to their concern
