I am very much interested in network security since my school days and as of now in my college i have worked on building my own encryption cipher .
But the point is i really dont know on which way to proceed ?
I mean network security is a very vast field.
I do have programming experiences on C/C++ , but i am looking for a field which is very adventurous and dynamic , well by dynamic i mean is that it must involve me every time not like programming , that once u build the code the job is done (of course u have operation and maintainence , but sounds boring to me )
Is there any particular field in network security which meets my requirements ?
