Do I need to set a banner in CISCO Networking configuration? I have to configure a router to make sure, that this configuration, will not be taken from other networks, that will try to access my network system illegally. Can you help me with this problem?
To specify a message-of-the-day (MOTD) banner, use the banner motd global configuration command. This is one of the important fact when you configure a network, this configuration helps you to protect the network when someone is trying to connect to your network. The message will appear and you have to type the motd banner. The purpose of MOTD banner is the authorization, of your network that authorizes, that you are the one who configured the network.
Banners were created to give security warnings to anyone who connects to the router either via telnet or an auxiliary port. Of course they are not mandatory nor do they speed up the router but they make maintenance and troubleshooting of a network so much easier.
MOTD (message of the day) is the most common type of banner.
Below is how you would configure your router to have a banner:
Router(config)#banner motd
Router(config)#banner motd #
Enter TEXT message. End with the character ‘#’.
$ DO NOT LOG IN #
Router(config)#^Z
Router#
Router#exit
Protecting your network system will require applying more than approach. Safety and Security Center and physical security are other common approaches used to protect a network.
