After you finish installing and configuring AlienVault USM (with OTX enabled), you will be able to quickly see which alarms indicate malicious activity from a known bad actor on the Alarms page. For more information, see Using OTX in AlienVault USM.
To enable OTX in your AlienVault USM installation, you must enter the OTX key and connect to your OTX account. If you do not have an OTX account and would like to sign up for it, you can do so from the Getting Started Wizard.
To join OTX from the Getting Started Wizard On the Join OTX screen, click Sign Up Now.
A popup takes you to the sign-up page on https://otx.alienvault.com/accounts/signup/.
Fill out the information (username, email address, and password) and click Sign Up.
A page appears informing you that a verification email with a link to OTX was sent to the email address you provided.
After you receive the email, click the link and, on the confirmation page for logged-in AlienVault USM users, click Login.
An AlienVault USM key page appears, displaying your OTX key and stating that the username you used to register for OTX is logged in.
Click Next.
The Thank You for Joining the Open Threat Exchange page appears.
Click Finish.
Important: After you click Finish, you cannot run the Getting Started Wizard again.
