The status reported for the interface still is given as up, even if carrier detect is not high, which is unlike the show serial interface display The only time the interface will report a down condition is if the encapsulation type is not set for the interface The line protocol display behaves the same as the line protocol for the serial interface Other than the interface and line protocol status, the show interface async 1 command is as useful for monitoring throughput, drops, and resets as it is for serial interfaces One additional set of information that the show interface command provides is related to the fact it uses PPP encapsulation With this configuration, the show command reports the status of the PPP, LCP, and NCP protocols These reports are the most valuable when multiple protocols are being used on the one link For example, if IP and IPX are being used on this interface, you would expect to see the ipcp and ipxcp state as negotiated when a user has dialed in If the user is experiencing difficulty in accessing some applications and not others over the dial link, it might be because one of the protocols has not successfully negotiated In this situation, the interface and line protocol will report up, and the only indication that one of the protocols in use over the link has failed is the state of the NCP negotiations The major omission for the show interface async 1 display is in reporting the status of EIA signals This is given in the show line 1 command, which is illustrated in Fig 8-10

In this chapter you learned some best practices for securing your network It is important to remember to implement security in layers and not to rely on just one method of securing your systems In this chapter you have seen the dot dot attack, which is launched by a hacker typing a URL into the web browser that navigates the folder structure on the server and can be used to delete files This shows that if you were not patching the server but relying only on a firewall, you would be vulnerable to the attack You have learned a number of operating system features that are used to secure systems, such as authentication and authorization Authentication is the process by which a user presents logon credentials that are then verified by the network server against a database; if the credentials are correct, the user is allowed to access the network After a user has been authenticated, an access token is generated that is used to authorize the user to access various network resources A network resource uses an access control list to determine who is allowed access A firewall is a device used for protecting one network from a second interconnected network, such as the Internet Firewalls compare the data passing through them with rules set up to allow or deny access There are several architectures for firewalls; three of them are dual-homed host, screened host, and screened subnet A dual-homed host firewall has two network interfaces and acts as a gateway between the two networks A screened-host firewall has a screening router placed between the public network and
