Use Password Safe as an external credential provider for Tenable.io asset scans

This guide provides information and steps for integrating Tenable.io with BeyondTrust Password Safe.

Security administrators know that conducting network vulnerability assessments means getting access to, and navigating, an ever-changing sea of usernames, passwords, and privileges.

Tenable.io is a cloud-based vulnerability management platform that is designed to help organizations identify and manage security risks across their entire IT infrastructure. By integrating Tenable applications with BeyondTrust Password Safe, customers have more choice and flexibility.

The benefits of integrating Tenable with Password Safe include:

• Credential updates directly in Tenable applications, requiring less management.
• Reduced time and effort documenting where credentials are stored in the organizational environment.
• Automatic enforcement of security policies in specific departments or business unit requirements, simplifying compliance.
• Reduced risk of unsecured privileged accounts and credentials across the enterprise.

Configure Password Safe

To use the integration, the following items must be configured in Password Safe:

• API registration.
• API account and group with correct permissions.
• Asset must exist in Password Safe with the same asset name as in Tenable.io (case sensitive).
• Managed asset must exist in Password Safe with the same asset name as in Tenable.io (case sensitive).
• Managed account used for Tenable scan. This account must be API enabled and be linked to the managed asset.

ℹ️

The managed account must be a shared account and not a dedicated account.

• Access policy that allows the API group or user to request the managed account.

Create an API registration

In Password Safe, all APIs must be registered. To register a new API:

1. In the BeyondInsight console, go to Configuration > General > API Registrations.
2. Click Create API Registration.
3. Select API Key Policy.
4. Provide a name for the API registration.
5. You must add an IP authentication rule for the address of your Tenable.io instance:
   • Click Add Authentication Rule.
   • From the Type dropdown, select Single IP Address.
   • Leave the IP Rule option selected.
   • Provide the IP Address.
   • Click Create Rule.
6. You must also add the IP range of the managed assets to be scanned.
   • Click Add Authentication Rule.
   • From the Type dropdown, select IP Range.
   • Leave the IP Rule option selected.
   • Provide From and To IP addresses.
   • Click Create Rule.
7. Click Create Registration.

The API Key is required for the Tenable.io configuration.

Create an access policy

Before you can configure an API group, you must have an access policy for the group that allows managed accounts to be requested and allows for API callers to override the automatic password changes after they are released. Create the access policy as follows:

2. Select an existing access policy or create a new one.
3. In the access policy, click Create Schedule and select the appropriate options.
4. Under Policy Types, toggle View Password to enable it.
