Scan Images in Sonatype Nexus Registry

Edit on GitHub

To scan a repository in Sonatype Nexus Registry, create a new registry scan setting.

Prerequisites

You have installed a Container Defender somewhere in your environment.

Configure the connector port for the Docker engine to connect to the Nexus registry.

The Docker client needs the Docker registry exposed at the root of the host together with the port that it is accessing. Nexus offers several methods to overcome this limitation, one of which is the connector port method, which Prisma Cloud supports.

From the Nexus web portal, select the Administration screen.

Select the Nexus Repository.

Select Online
to allow the Nexus repository to accept the incoming requests.

Configure the Docker repository connector to use an HTTP or HTTPS port.

The Defender can establish a connection with the Nexus registry over the connector port that you configured in the Nexus registry.

Ensure that the port is open for the image to be accessed successfully.

Add a Nexus registry in Prisma Cloud

Select Add registry
.

In the Add New Registry Setting Specification
, enter the following values:

In the Version
drop-down list, select Sonatype Nexus
.

In Registry
, enter the hostname, or Fully Qualified Domain Name (FQDN), and the connector port for the Nexus registry’s login server.

The format for the FQDN is <hostname>:<connector_port>
, where <hostname>
is a unique value specified when the registry was created, and the <connector_port>
is the one you configured in the Nexus repository administration.

Example: <http|https://<nexus_hostname>:<HTTP/HTTPS connector port for the specific Nexus repo>
.

https://ec2-100-25-223-135.compute-1.amazonaws.com:8083

Leave the Repository
blank or include a pattern to match the Docker repositories inside the Nexus registry.

For example: To scan all the images under a path, include the path/to
string.

In Tag
, enter an image tag. Leave this field blank to scan all images, regardless of their tag.

In Credential
, configure how Prisma Cloud authenticates with Nexus registry.

Select a credential from the drop-down list.

If there are no credentials in the list, click Add
to create new credentials and select the Basic authentication.

In OS type
, specify whether the repo holds Linux
or Windows
images.

In Scanners scope
, specify the collections of defenders to use for the scan.

Console selects the available Defenders from the scope to execute the scan job according to the Number of scanners
setting. For more information, see deployment patterns.

In Number of scanners
, enter the number of Defenders across which scan jobs can be distributed.

In Cap
, limit the number of images to scan.

Set Cap
to 5
to scan the five most recent images, or enter a different value to increase or decrease the limit. Set Cap
to 0
to scan all images.

Select Add
.

Select Save and scan
.

Verify that the images in the repository are being scanned.

Go to Monitor > Vulnerabilities > Images > Registries

A progress indicator at the top right of the window shows the status of the current scan. As the scan of each image is completed, the finding results display in the table.

To get details about the vulnerabilities in an image, click on it.

To force a specific repository to be scanned again, select Scan
from the top right of the results table, then click on the specific registry to rescan.
