Configure Nessus

Before you begin:

• Install Nessus.

When you access Nessus in a browser, a warning appears to regard a connection privacy problem, an untrusted site, an unsecure connection, or a related security certificate issue. This is 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.

To configure Nessus:

1. Follow the Install Nessus instructions to open to the Welcome to Nessus screen in your browser.

2. On the Welcome to Nessus screen, select how you want to deploy Nessus.

3. Follow the configuration steps for your selected product:
• Install Nessus Essentials, Professional, or Manager
• Link to Tenable.io
• Link to Tenable.sc
• Link to Nessus Manager
• Link a Node (Nessus Manager cluster)
• Manage Nessus Offline
