Warning Banners

This chapter is short, but very important. Every router should have an appropriate warning banner for all login access. These banners, however, are often thought of as pure fluff by those technically inclined. How could a warning banner serve as any protection against a hacker? What hacker is going to go away because a warning banner tells him to? It is important to remember that warning banners are not implemented to provide technical protection. They provide legal protection.
