How to Best Use This Chapter

Computer networks are a vital component to the operation of most businesses. Protecting these networks from attacks using firewalls is also vital. Many businesses deploy some type of power backup (on critical systems) to insure that these important components continue to operate in the case of a temporary power failure. Similarly, depending on a single device to protect important networks is not acceptable in many environments. Using multiple PIX Firewalls operating in a failover configuration enables your network to remain operational (and protected from attack) even if a single PIX Firewall fails. Test yourself with the "Do I Know This Already?" quiz and see how familiar you are with the failover functionality available on PIX Firewalls.
