We previously saw that the upswing P2P applications have experienced is also
due to ease of installation and use, the low cost (most of the time free) and its
great rewards. Even novice users have little difficulty using such applications
to download files that other users shared intentionally or accidentally shared on
the P2P network.
This is yet another security problem P2P applications are posing. Empowering
a user, especially a novice, to make choices regarding the accessibility of their
files is a significant risk. Because of it’s convenient and familiar look, applications
