You can configure Autokey for NTP server from the Cisco ISE CLI in Configuration Mode. WithĪutokey, all key distribution and management functions involve only public values, which considerably simplifies key distribution Public-key cryptography is generally considered more secure than symmetric-keyĬryptography because the security is based on a private value, which is generated by each server and never revealed.

NTPv4 uses symmetric-key cryptography and also providesĪ new Autokey scheme based on public-key cryptography.

This procedure ensures that the reports and logs from the various nodes in your deployment are always in sync with regardĬisco ISE also supports public-key authentication for NTP servers. You can also specify whether or not Cisco ISE should use only authenticated NTP servers, and you can enter one or more authentication keys for that purpose.Ĭisco recommends that you set all Cisco ISE nodes to the Coordinated Universal Time (UTC) timezone -especially if your Cisco ISE nodes are installed in a distributed deployment.

You can reset the password for that administrator ID, as described in the 'Reset a Disabled Password Due to Administrator If you choose to get locked out, the Admin portal 'locks you out' of the system.Ĭisco ISE adds a log entry in the Server Administrator Logins report, and suspends the credentials for that administrator Specified time or locked out (as configured).
