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.
