How To Set Password On Cisco Router

We will starting time with physical security, followed by bones controls like implementing a password strategy, sign posting via login banners, and the employ of SSH for improved and confidential configuration management.

Mutual Threats to Physical Installations

Information security policies should exist based on take chances analysis and run a risk management. Adventure is based on the probability of threats exploiting assets with certain vulnerabilities. We have had threats to physical installations since the dawn of networking; nonetheless, these threats are augmented by some of the technology transit we see now a days. For example, information technology is a lot more likely to practice poor handling of key electrical components in a modular device switch or router that requires installation of modules, installation of blades, and network cards to either expand its functionality or add more horsepower.

Ability loss and other electric threats become a big issue, knowing how nosotros are consolidating devices, servers, and applications in information centers and trying to scale up to the number of connections and number of users that we want to serve. This tin can put a strain in our power direction components and may result in a security incident, non necessarily related to a malicious attack.

Configuring Router Countersign

Simply over again, the security is a multidimensional practice then not merely practice nosotros demand to care nigh physical threats and physical security, but likewise admission command and management command into the routers.

RouterX(config)#no aaa new-model
RouterX(config)#line console 0
RouterX(config-line)#login
% Login disabled on line 0, until 'password' is gear up
RouterX(config-line)#password cisco
RouterX(config-line)#exi
RouterX(config)#line vty 0 4
RouterX(config-line)#login
% Login disabled on line ii, until 'password' is set
% Login disabled on line 3, until 'password' is ready
% Login disabled on line four, until 'password' is set
% Login disabled on line 5, until 'password' is ready
% Login disabled on line 6, until 'countersign' is fix
RouterX(config-line)#password sanjose
RouterX(config-line)#exi
RouterX(config)#enable countersign cisco
RouterX(config)#enable secret sanfran
RouterX(config)#service password-encryption

We accept seen these commands already to configure line access into the device for management purposes. Each line can have its ain password, or you can tie all of the lines to a local user database. You could fifty-fifty retrieve about transporting or centralizing that user database in the grade of a AAA server and have all devices querying that server in order to obtain authentication information.

Direction should too be based on roles; this is what we know as part-based access command and and so you should have users for certain functions in the device and other users that have admission to privileged functions, which initially are set up and defined by the enable and enable hole-and-corner commands.

Even if you are using local hallmark it is highly advisable to have users divers with appropriate privilege level. To force a user login procedure (Authentication) you need to switch to "AAA new-model" and to create a user. Once again if you are using secret instead of password your configuration volition exist stronger.

RouterX(config)#aaa new-model
RouterX(config)#username admin privilege 15 hole-and-corner learncisconet
RouterX(config)#
RouterX(config)#aaa authentication login default local
RouterX(config)
