Scan App-Embedded Workloads

App-Embedded Defenders can scan their workloads for vulnerabilities.

To see the scan reports, go to Monitor > Vulnerabilities > Images > Deployed You can filter the table by:

• App-Embedded: Select — Narrows the results to just images protected by App-Embedded Defender.
• App ID — Narrows the list to specific images. App IDs are listed under the table’s Apps column.

  For ECS Fargate tasks, the App ID is partially constructed from the task name. AWS Fargate tasks can run multiple containers. All containers in a Fargate task have the same App ID.

  For all other workloads protected by App-Embedded Defender, the App ID is partially constructed from app name, which is a deploy-time configuration set in the App ID field of the embed workflow.

You can use wildcards to filter the table by app/image name. For example, if the app name is dvwa, then you could find all deployments with Repository: dvwa*. This filter would show dvwa:0438dc81a9144fab8cf09320b0e1922b and dvwa:538359b5f7f54559ab227375fe68cd7a.

Create vulnerability rules

Create a vulnerability rule for a segment of App-Embedded workloads.

1. Login to the Console.
2. Go to Defend > Vulnerabilities > Images > Deployed.
3. Click Add rule.
4. Entar a rule name.
5. Click on Scope to select a relevant collection, or create a new collection.

   Workloads are scoped by App ID. App ID is specified when you embed the App-Embedded Defender into a workload, and it’s a unique identifier for the Defender/task pair.

   1. If creating a collection, click Add collection.
   2. Enter collection name.
   3. In the App ID field, enter one or more App IDs.

      Postfix wildcards are supported.
   4. Click Save.
   5. Select the new collection.
   6. Click Select collection.
6. Select an alert threshold.

   Thresholds select, by severity, which vulnerabilities Prisma Cloud should report.

   App-Embedded Defenders don’t support the block action.
7. Click Save.

Deploy an example Fargate task

Deploy the fargate-vulnerability-compliance-task Fargate task. Follow the steps in embed App-Embedded Defender into Fargate tasks.

You can use the following task definition to test Prisma Cloud’s App-Embedded Defender. It’s based on an Ubuntu 18.04 image.

{
  "containerDefinitions": [
     {
        "command": [
           "/bin/sh -c 'cp /bin/sleep /tmp/xmrig && echo \"[+] Sleeping...\" && while true; do sleep 1000 ; done'"
        ],
        "entryPoint": [
           "sh",
           "-c"
        ],

              "awslogs-region": "us-east-1",
              "awslogs-stream-prefix": "ecs"
           }
        },
        "name": "Fargate-vul-comp-test",

Review vulnerability scan reports

Review the scan results in Console.

If an App-Embedded Defender protects a container where the user isn’t root, the vulnerability and compliance scanning procedure will encounter permission denied errors that you can see in the Defender logs (Manage > Defenders > Manage > Defenders > Actions > Logs).

If an App-Embedded Defender protects a Fargate task with a container where the user isn’t root, the vulnerability and compliance scanning procedure will also encounter permission denied errors. However, the errors won’t be visible unless you download and inspect the Defender logs.

In both cases, the scan flow continues even though errors are encountered.

For Fargate version 1.3.0 and older, Prisma Cloud shows only a single scan report if the same image is run simultaneously as:

• A task on ECS Fargate, protected by App-Embedded Defender.
• A container on a host, protected by Container Defender.

In this case, the image is categorized as "App-Embedded". As a result, when the scan report table is filtered by App-Embedded: Select, a scan report will be shown. When the table is filtered by App-Embedded: Exclude, it will be hidden. And when filtering by Hosts, it will be hidden, even if the host matches, because the image is considered as App-Embedded.

For Fargate version 1.4.0, two separate scan reports are shown, one for App-Embedded and one for Container Defender.

1. Navigate to Monitor > Vulnerabilities > Images > Deployed and validate that the deployed image appears and contains vulnerabilities.
2. To see all images that are related to Fargate tasks, filter the image table by App-Embedded: Select.

   You can also filter the results by a specific task name or postfix wildcards. For example, fargate-task or fargate-task*.
3. Search for the fargate-vulnerability-compliance-task Fargate task.
4. Click on the image to see more details.

   The Apps column shows a count of the number of running containers protected by App-Embedded Defender.

   The Layers, Processes info, Labels, Runtime, and Trust groups tabs aren’t supported for images scanned by App-Embedded Defenders.

   1. Click the Vulnerabilities tab to review all findings.

      
   2. Review runtime information for the container.

      Go to the Environment > Apps tab, and then click on the app in the table to open the App-Embedded observations. You can bring up the same view by going directly to Monitor > Runtime > App-Embedded observations, and clicking on the same app.

      

      The Environment tab shows cloud-provider metadata that App-Embedded Defender collected about the running container. For more information about the type of cloud-provider metadata App-Embedded Defender can collect, see Monitoring workloads at runtime.
