Running Authenticated Asset Scans

Role Availability Read-Only Investigator Analyst Manager

An authenticated asset An IP-addressable host, including but not limited to network devices, virtual servers, and physical servers. scan verifies scanned Internet Protocol (IP) addresses and detects vulnerabilities. Log in Log in (verb): Process in which an individual gains access to a computer system after providing sufficient credentials to authenticate their unique identity. Login (noun): User credentials, typically a username and matching password. as administrator or root High-level user account with full administrative privileges. to perform an authenticated scan Authenticated scans are performed from inside the machine using a user account with appropriate privileges.. See Managing Credentials in USM Anywhere for more information.

Warning: An authenticated scan may fail if the local mail exchanger, which applies to Linux hosts Reference to a computer on a network., is enabled in the target asset.

You cannot scan USM Anywhere Sensors.

You can scan an instance or network, but first you need to check these points:

  • The sensor reaches the targets

  • The sensor is able to scan their ports

If your USM Anywhere Sensor is deployed in Amazon Web Services (AWS) to a virtual private cloud (VPC), see Amazon VPC-to-Amazon VPC connectivity options for more information.

The following table shows the asset scan credentials and escalation options.

Asset Scan Credentials and Escalation Options
Operating System Method and Credentials Escalation
Linux, BSD, Solaris, or macOS SSH Program to securely log into another computer over a network, execute commands in a remote machine, and move files from one machine to another through Secure Copy (SCP). password or public key Cryptographic key that can be used by anyone to encrypt messages intended for a particular recipient, such that the encrypted messages can be deciphered only by using a second key that is known only to the recipient (the private key). authentication Process used to verify the identity of a user, user device, or other entity, usually through a username and password. sudo A program for UNIX-like computer operating systems that allows users to run programs with the security privileges of another user, by default the superuser. or su

Note: If a scan is suspended or otherwise running for more than two hours, it will time out. You can see the timeout result in the asset's Scan History, as well as in the system event generated for that scan.

To run an authenticated asset scan from Assets

  1. Go to Environment > Assets.
  2. Complete one of these options:
    • Next to the asset name that you want to scan, click the icon select Full Details, and then select Actions > Authenticated Scan.

      or

    • Next to the asset name you want to scan, click the icon and select Authenticated Scan to directly start the asset scan. If the option is not enabled, you need to add a credential. See Managing Credentials in USM Anywhere for more information.

    A message displays at the top of the page to inform you that the authenticated scan is in progress.

    Important: Credentials assigned directly to an asset have higher priority than those assigned to an asset group.

  3. In the asset details page, click Scan History in the table area to display the results of the scan.

    You can see the status of each scan and its details, which informs you if the scan is unsuccessful due to bad credentials or a connectivity issue between the USM Anywhere Sensor Sensors are deployed into an on-premises, cloud, or multi-cloud environment to collect logs and other security-related data. This data is normalized and then securely forwarded to USM Anywhere for analysis and correlation. and the asset you are attempting to scan. USM Anywhere also creates a system event named Authenticated Asset Scanner Result for the scan and for testing the credentials.

    Each asset has a Scan Details link you can click to download a zip file containing the details of the recent scan. The link is only present for the most recent scan of each asset, and is available for one week after the scan has been run.

  4. Below the Vulnerabilities tab, you can see the vulnerabilities that the scan has found.

    You can also see the vulnerabilities that the scan has found by going to Environment > Vulnerabilities. While the scan is running, a Scanning button displays. When the scan finishes, the message Scan finished. Refresh to view scan results displays. Click Refresh Scan Results to update the list.
