Configure Nessus

Before You Begin

When you access Nessus in a web browser, a warning appears regarding a connection privacy problem, an untrusted site, an unsecure connection, or a related security certificate issue. This is expected and normal behavior. Nessus provides a self-signed SSL certificate.

Refer to the Security Warnings section for steps necessary to bypass the SSL warnings.

Note: Depending on your environment, plugin configuration and initialization can take several minutes.

1. On the Create an account window, enter a username and password for the Nessus System Administrator account.

   Note: Passwords cannot contain Unicode characters.

2. Click the Continue button.
