Telnet gibi güvenlik açığı olan bir protokol kullanmak yerine giriş bilgilerinizi ve verileri akışlarınızı şifreleyecek daha güvenli olan bir protokol olanSecure Shell (SSH) kullanabilirsiniz. Bu sizi ve verilerinizi daha güvende hisetmenizi sağlayacaktır.
Şimdi adım adım SSH nasıl kurulacağını göreceğiz:

1. Hostname settings are made:

2. The domain name is set (here hostname and domain name are required to generate encrypted keys):

3. Encrypted keys are generated to securely conduct the session:

4. We create a username and password.

6. The maximum number of incorrect entries is set for an SSH connection:

7. We will determine the SSH version.

8. A connection to the vty lines of the router is established:
