RADIUS uses this special username for enable authentication.
#Cisco router vs netgear router mac address spoofing secure password
If using RADIUS, create a user named $enab15$ and set the enable password for it. If using TACACS+, configure a TACACS+ enable password per user. Step 4 Enforce enable authentication: Authenticate enable access with TACACS+ or RADIUS, and use local enable as fallback method. aaa authentication login group local-case Use RADIUS or TACACS+ as the primary method, and local authentication as fallback. Step 3 Enforce login authentication: Define a login authentication method list and apply it to console, VTY and all used access lines. ! Define the source interface to be used to communicate with the TACACS+/RADIUS servers Radius-server host auth-port 1645 acct-port 1646 key Tacacs-server host single-connection key Set source IP address for TACACS+ or RADIUS communications. If possible, use a separate key per server. Step 2 Define server groups: Set server groups of all AAA servers. Configure aaa session-id common to ensure the session ID is maintained across all authentication, authorization, and accounting packets in a session. Step 1 Enable AAA: Enable AAA with the aaa new-model global command. TACACS+ and RADIUS configurations templates are provided in Appendix A, "Sample Configurations." All management access (SSH, telnet, HTTP and HTTPS) should be controlled with AAA. Unauthorized attempts and actions to access or use this system may result in civil and/orĪll activities performed on this device are logged and monitored.ĪAA is the primary and recommended method for access control. You must have explicit, authorized permission to access or configure this device. UNAUTHORIZED ACCESS TO THIS DEVICE IS PROHIBITED Login banner examples are provided in Appendix A, "Sample Configurations."

With the guidance of a legal professional create and apply a login banner. Also note that some devices may have more than 5 VTYs. Note that line passwords are used for initial configuration and are not in effect once AAA is configured. Step 3 Line passwords: define a line password for each line you plan to use to administer the system. The locally configured enable password will be used as a fallback mechanism after AAA is configured. Enable access should be handled with an AAA protocol such as TACACS+ or RADIUS. Step 2 Enable secret: Define a local enable password using the enable secret global command. Router(config)# service password-encryption Once configured, all passwords are encrypted automatically, including passwords of locally defined users. Step 1 Global local password encryption: enable automatic password encryption with the service password-encryption global command. In addition to enforcing a strong password policy, secret information and password should be protected with the use of encryption. Protect Local PasswordsĪs described in Restrict Infrastructure Device Management Accessibility, page 2-3, infrastructure devices always have local passwords and secret information that need to be properly secured.

This chapter provides detailed guidance on how to implement each tool and best practice, along with plenty of templates and examples. The reader may use this chapter as a starting point, and later continue implementing the more advanced tools also part of the security baseline. It presents an initial subset of tools and best practices that provide most value and with a minimal operational impact. This chapter explains how to get started with the security baseline.
