Manually Set Up Prisma Cloud Role for AWS Accounts

Download CFT template from Prisma Cloud.
See Onboard Your AWS Account and follow the steps to
Download IAM Role CFT
.
Search for the
ExternalID
field within the template.
Copy the
ExternalID
value, which you will need to paste in the AWS console as described in the next Step.
Log in to the AWS management console to create a role for Prisma Cloud.
Refer to the AWS documentation for instructions. Create the role in the same region as your AWS account, and use the following values and options when creating the role:
Type of trusted entity:
Another AWS Account
and enter the
Account ID
:
188619942792
Select
Require external ID
and paste the
ExternalID
value that you copied in Step 1 above.
Do not enable MFA. Verify that
Require MFA
is not selected.

Click
Next
and add the AWS Managed Policy for
Security Audit
.

Add a role name and create the role. In this workflow, later, you will create the granular policies and edit the role to attach the additional policies.
Get the granular permissions from the AWS CFT for your AWS environment.
The Prisma Cloud S3 bucket has read-only templates and read-and-write templates for the public AWS, AWS GovCloud, and AWS China environments.
Download the template you need.

If you have onboarded your AWS accounts on Prisma Cloud after December 8, 2022, you do not need to download the static CFTs from the

Links to Legacy CFTs

below. For backward compatibility, Prisma Cloud will support onboarding using static CFTs until further notice.

Identify the permissions you need to copy.

To create the policy manually, you will need to add the required permissions inline using the JSON editor. From the read-only template you can get the granular permissions for the

PrismaCloud-IAM-ReadOnly-Policy

, and the read-write template lists the granular permissions for the

PrismaCloud-IAM-ReadOnly-Policy

and the

PrismaCloud-IAM-Remediation-Policy

.

For AWS accounts you onboard to Prisma Cloud, if you do not use the host, serverless functions, and container capabilities enabled with Prisma Cloud Compute, you do not need the permissions associated with these roles:

PrismaCloud-ReadOnly-Policy-Compute
role—CFT used for Monitor mode, includes additional permissions associated with this new role to enable monitoring of resources that are onboarded for Prisma Cloud Compute.
PrismaCloud-Remediation-Policy-Compute
role—CFT used for Monitor & Protect mode, includes additional permissions associated with this new role to enable read-write access for monitoring and remediating resources that are onboarded for Prisma Cloud Compute.

Open the appropriate template using a text editor.

Find the policies you need and copy it to your clipboard.

Copy the details for one or both permissions, and make sure to include the open and close brackets for valid syntax, as shown below.




Create the policy that defines the permissions for the Prisma Cloud role.
Both the read-only role and the read-write roles require the AWS Managed Policy
SecurityAudit Policy
. In addition, you will need to enable granular permissions for the
PrismaCloud-IAM-ReadOnly-Policy
for the read-only role, or for the read-write role add the
PrismaCloud-IAM-ReadOnly-Policy
and the limited permissions for
PrismaCloud-IAM-Remediation-Policy
.
Select
IAM
on the AWS Management Console.
In the navigation pane on the left, choose
Access Management
Policies
Create policy
.
Select the
JSON
tab.
Paste the JSON policies that you copied from the template within the square brackets for Statement.


If you are enabling read and read-write permissions, make sure to append the read-write permissions within the same Action statement.

Review and create the policy.
Edit the role you created previously and attach the policy to the role.

Required only if you want to use the same role to access your CloudWatch log group
Update the trust policy to allow access to the CloudWatch log group.
Edit the
Trust Relationships
to add the permissions listed below. This allow you to ensure that your role has a trust relationship for the flow logs service to assume the role and publish logs to the CloudWatch log group.
{
      "Effect": "Allow",
      "Principal": {
        "Service": "vpc-flow-logs.amazonaws.com"
      },
      "Action": "sts:AssumeRole"
}
Copy the
Role ARN
.

Resume with the account onboarding flow in Onboard Your AWS Account
