You might have difficulties understanding the user privileges, but if you want to give full access to a user you have to set the user privilege level to 15.

To connect to a VTY, users must present a valid password.”Ĭisco upgrades their devices’ IOS very often. describes how to configure the Intelligence Engine 2100 (IE2100) Series Cisco Networking Services (CNS) embedded agents on your Catalyst 2950. “Virtual teletype ( VTY) is a command line interface (CLI) created in a router and used to facilitate a connection to the daemon via Telnet, a network protocol used in local area networks. This is how it will look on the running config: R1(config)#enable algorithm-type sha256 secret “***” Now, we will need to enable secret on the global interface: R1(config)#crypto key generate RSA modulus 1024 R1(config)#ip domain-name test and is impossible to convert to clear text.Ģ. Well, as you can see I haven’t crossed the secret (password). R1(config)# username “test” privilege 15 algorithm-type sha256 secret “cisco123” This makes it suitable when it is appropriate to compare ‘hashed’ versions of texts, as opposed to decrypting the text to obtain the original version.”
“A hash is not ‘encryption’ – it cannot be decrypted back to the original text (it is a ‘one-way’ cryptographic function, and is a fixed size for any size of source text).

PC> telnet 192.168.1.This post will show you how to configure and enable SSH connection between your PC to any Cisco device.
It will prompt you to enter TELNET password – i.e., nortel123. From a PC, we can access the router, and also configure it through a TELNET port, but only from those which are connected with that router.Īs shown below: Accessing the router from Norman Laptop: The telnet password can work with devices with telnet enabled on them. Password:norman123 (entering the secret password) Password:norcon123 (entering the console password) It encrypts passwords that are stored in router or switch configuration files. This is a security vulnerability since anyone can view them just by looking at the running-config or start-up config. How does the service password-encryption command enhance password security on Cisco routers and switches It encrypts passwords as they are sent across the network. on our Cisco devices, these passwords are visible as a clear text in the running-config. (which will encrypt the above simple password)Ĭonsole and Telnet interface do not allow to enter “Secret”. When we configure passwords like Privileged Mode password, VTY line password, Console line password, etc. Norman_Router(Config)# service password-encryption Norman_Router(config-line)#password nortel123 (using different passwords for different connections increases the security) Norman_Router(Config)# line vty 0 1 ( 0 1 which means two lines are open at a time, so two people can access the router through telnet simultaneously.) Norman_Router(Config-line)# login (verifying password at login time) Incomplete or incorrect configurations are a vulnerability that attackers can exploit. Norman_Router(Config-line)#password norcon123 (using different passwords for different connections increases the security) Configure a Cisco Switch for Peace of Mind Completing simple tasks like configuring passwords and creating network access lists controls who can access the switch can enable you to stay secure online. Password:norman123 (after entering this secret you will able to access privilege mode) I recommend you use “secret” instead of “password”.

Secret is more secure, and there are no changes to crack the HASH Code, because no one in the world has cracked the HASH Code. While in secret, the secret string “norman123” is converted to HASH, which is irreversible – which means it cannot be revealed by reversing the formula. These Encrypted Strings can also be decrypted, which means the attacker can attack if you have kept the password. You can also use off-line analyzer to find in all configuration backups the devices, where are not. In SwitchBackup, you can use predefined snippet Encrypt password and apply it to all devices in the domain at once. In password, the password string “norman123” gets encrypted, and it is stored in the router’s running-config. to encrypt all paswords in plain text configuration file on Cisco network devices. What is the difference between the “password” and “secret”? Norman_Router(Config)# enable secret norman123 (recommended) Norman_Router(Config)# enable password norman123
The password authentication can be done at user level, console and telnet. For remote connection to router or switch, you need to enable ssh on Cisco router and configure ssh correctly. The first step towards security is to make it password protected at all the connections. Easy configure ssh on Cisco router or switch. The router can be made secure by preventing others from accessing it.
