配置路由器使用Cisco AutoSecure 实验过程： R1#auto secure --- AutoSecure Configuration --- *** AutoSecure configuration enhances the security of the router, but it will not make it absolutely resistant to all security attacks *** AutoSecure will modify the configuration of your device. All configuration changes will be shown. For a detailed explanation of how the configuration changes enhance security and any possible side effects, please refer to Cisco.com for Autosecure documentation. At any prompt you may enter '?' for help. Use ctrl-c to abort this session at any prompt. Gathering information about the router for AutoSecure Is this router connected to internet? [no]: yes Enter the number of interfaces facing the internet [1]: Interface IP-Address OK? Method Status Protocol FastEthernet0/0 unassigned YES unset administratively down down Ethernet1/0 unassigned YES unset administratively down down Ethernet1/1 unassigned YES unset administratively down down Ethernet1/2 unassigned YES unset administratively down down Ethernet1/3 unassigned YES unset administratively down down Enter the interface name that is facing the internet: FastEthernet0/0 Securing Management plane services... Disabling service finger Disabling service pad Disabling udp & tcp small servers Enabling service password encryption Enabling service tcp-keepalives-in Enabling service tcp-keepalives-out Disabling the cdp protocol Disabling the bootp server Disabling the http server Disabling the finger service Disabling source routing Disabling gratuitous arp Here is a sample Security Banner to be shown at every access to device. Modify it to suit your enterprise requirements. Authorized Access only This system is the property of So-&-So-Enterprise. UNAUTHORIZED ACCESS TO THIS DEVICE IS PROHIBITED. You must have explicit permission to access this device. All activities performed on this device are logged. Any violations of access policy will result in disciplinary action. Enter the security banner {Put the banner between k and k, where k is any character}: k www.norvel.com.cn k Enable secret is either not configured or is the same as enable password Enter the new enable secret: Confirm the enable secret : Enter the new enable password: Choose a password that's different from secret Enter the new enable password: % Password too short - must be at least 6 characters. Password configuration failed Enter the new enable password: Confirm the enable password: Configuration of local user database Enter the username: suyajuncn Enter the password: Confirm the password: Configuring AAA local authentication Configuring Console, Aux and VTY lines for local authentication, exec-timeout, and transport Securing device against Login Attacks Configure the following parameters Blocking Period when Login Attack detected: Device not secured against 'login attacks'.
