2015-06-17

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'.
 
Configure SSH server? [yes]: yes
Enter the domain-name: blog.norvel.com.cn
Configuring interface specific AutoSecure services
Disabling the following ip services on all interfaces:
 no ip redirects

Securing Forwarding plane services...
Enabling CEF (This might impact the memory requirements for your platform)
Enabling unicast rpf on all interfaces connected
to internet
Configure CBAC Firewall feature? [yes/no]: yes
