Securing Remote Access to a Cisco Router Using SSH

Securing Remote Access to a Cisco Router Using SSH

Hashtags: #networksecurity #CiscoRouter #SSH #configuration

Are you looking to configure Secure Shell (SSH) on your Cisco Router for secure network access? Follow these steps to set up SSH on your router for secure access.

=>Set the domain name and hostname of your router using the following commands:

  • ip domain-name ccnaguru.com
  • hostname ccna

=>Generate an RSA key pair for secure communication using SSH by typing:

  • crypto key generate rsa general-keys modulus 4096
  • The name for the keys will be: ccna.ccnaguru.com
  • The key modulus size is 4096 bits
  • Generating 4096 bit RSA keys, keys will be non-exportable...[OK]
  • *Mar 1 0:3:4.769: %SSH-5-ENABLED: SSH 1.99 has been enabled

=>Set SSH version to 2 for improved security and set a timeout value and authentication retries using the following commands:

  • ip ssh version 2
  • ip ssh time-out 30
  • ip ssh authentication-retries 5

=>Configure the Virtual Terminal (VTY) lines to allow SSH connections using the following commands:

  • line vty 0 15
  • transport input ssh
  • login local
  • exit

=>Create a local user account for SSH authentication using the following commands:

  • username saeed password ahmad

=>Configure an interface with an IP address and enable it using the following commands:

  • interface f0/0
  • ip address 192.168.10.1 255.255.255.0
  • no shutdown

Now you can connect to your Cisco Router using SSH from your PC by using the following command:

  • ssh -l saeed 192.168.10.1

Implementing these steps will help you secure your network access by using SSH for secure communication with your Cisco Router. #networksecurity #CiscoRouter #SSH #configuration
