gives companies new possibilities in data exchange. Nowadays it is

service. Once installed, hardware security devices donít require
Software security packages on the other hand can provide you with
much greater protection. Generally software security packages
consist of the mixture of programs to ensure maximum protection is
achieved. Software is easy to update and that is why any kind of
newly discovered security weakness can be quickly patched up. The
