I’ve released a little paper with title An (In)security Overview on Analysis of Client-Server Software Applications that I think is self explainatory.
Here a little abstract:
The principal objective of this paper is to give a good detailed
panoramic view of the Security aspects involved in Client-Server based
Applications. The panoramics will be seen from the point of view of a
Reverse Engineer that should be aware of the Security Problems that are
directly releated to the Client-Server Software Structure.
