Set up templates and dashboards for Amazon Safety Lake information

Your subscriber for OpenSearch Ingestion is now prepared. Earlier than you configure OpenSearch Ingestion to course of the safety information, let’s configure an OpenSearch sink (vacation spot to put in writing information) with index templates and dashboards.

Index templates are predefined mappings for safety information that selects the proper OpenSearch area sorts for corresponding Open Cybersecurity Schema Framework (OCSF) schema definition. As well as, index templates additionally comprise index-specific settings for a specific index patterns. OCSF classifies safety information into completely different classes resembling system exercise, findings, identification and entry administration, community exercise, software exercise and discovery.

Amazon Safety Lake publishes occasions from 4 completely different AWS sources: AWS CloudTrail with subsets for AWS Lambda and Amazon Easy Storage Service (Amazon S3), Amazon Digital Non-public Cloud(Amazon VPC) Move Logs, Amazon Route 53, and AWS Safety Hub. The next desk particulars the occasion sources and their corresponding OCSF classes and OpenSearch index templates.

To simply determine OpenSearch indices containing Safety Lake information, we advocate following a structured index naming sample that features the log class and its OCSF outlined class within the title of the index. An instance is offered under

ocsf-cuid-${/class_uid}-${/metadata/product/title}-${/class_name}-%{yyyy.MM.dd}

8. To add these to OpenSearch Dashboards, select the hamburger menu, and beneath Administration, select Stack Administration.
9. Within the navigation pane, select Saved Objects.

10. Select Import.

11. Select Import, navigate to the downloaded file, then select Import.

12. Affirm the dashboard objects are imported accurately, then select Finished.

All the mandatory index and element templates, index patterns, visualizations, and dashboards are actually efficiently put in.

Configure OpenSearch Ingestion

Every OpenSearch Ingestion pipeline could have a single information supply with a number of sub-pipelines, processors, and sink. In our answer, Safety Lake managed Amazon S3 is the supply and your OpenSearch Service cluster is the sink. Earlier than establishing OpenSearch Ingestion, you have to create the next IAM roles and arrange the required permissions:

• Pipeline position – Defines permissions to learn from Amazon Safety Lake and write to the OpenSearch Service area
• Administration position – Defines permission to permit the consumer to create, replace, delete, validate the pipeline and carry out different administration operations

The next determine reveals the permissions and roles you want and the way they work together with the answer companies.

Earlier than you create an OpenSearch Ingestion pipeline, the principal or the consumer creating the pipeline will need to have permissions to carry out administration actions on a pipeline (create, replace, checklist, and validate). Moreover, the principal will need to have permission to move the pipeline position to OpenSearch Ingestion. If you’re performing these operations as a non-administrator, add the next permissions to the consumer creating the pipelines:

{
	"Model": "2012-10-17",
	"Assertion": [
		{
			"Effect": "Allow",
			"Resource": "*",
			"Action": [
				"osis:CreatePipeline",
				"osis:ListPipelineBlueprints",
				"osis:ValidatePipeline",
				"osis:UpdatePipeline"
			]
		},
		{
			"_comment": "Substitute {your-account-id} together with your AWS account ID",
			"Useful resource": [
				"arn:aws:iam::{your-account-id}:role/pipeline-role"
			],
			"Impact": "Permit",
			"Motion": [
				"iam:PassRole"
			]
		}
	]
}

Configure a learn coverage for the pipeline position

Safety Lake subscribers solely have entry to the supply information within the Area you chose if you created the subscriber. To offer a subscriber entry to information from a number of Areas, consult with Managing a number of Areas. To create a coverage for learn permissions, you want the title of the Amazon S3 bucket and the Amazon SQS queue created by Safety Lake.

Full the next steps to configure a learn coverage for the pipeline position:

1. On the Safety Lake console, select Areas within the navigation pane.
2. Select the S3 location akin to the Area of the subscriber you created.

3. Make an observation of this Amazon S3 bucket title.

4. Select Subscribers within the navigation pane.
5. Select the subscriber OpenSearchIngestion that you simply created earlier.

6. Pay attention to the Amazon SQS queue ARN beneath Subscription endpoint.

7. On the IAM console, select Insurance policies within the navigation pane.
8. Select Create coverage.
9. Within the Specify permissions part, select JSON to open the coverage editor.
10. Take away the default coverage and enter the next code (substitute the S3 bucket and SQS queue ARN with the corresponding values):

    {
    	"Model": "2012-10-17",
    	"Assertion": [
    		{
    			"Sid": "ReadFromS3",
    			"Effect": "Allow",
    			"Action": "s3:GetObject",
    			"Resource": "arn:aws:s3:::{bucket-name}/*"
    		},
    		{
    			"Sid": "ReceiveAndDeleteSqsMessages",
    			"Effect": "Allow",
    			"Action": [
    				"sqs:DeleteMessage",
    				"sqs:ReceiveMessage"
    			],
    			"_comment": "Substitute {your-account-id} together with your AWS account ID",
    			"Useful resource": "arn:aws:sqs:{area}:{your-account-id}:{sqs-queue-name}"
    		}
    	]
    }

11. Select Subsequent.
12. For coverage title, enter read-from-securitylake.
13. Select Create coverage.

You could have efficiently created the coverage to learn information from Safety Lake and obtain and delete messages from the Amazon SQS queue.

The whole course of is proven under.

Configure a write coverage for the pipeline position

We advocate utilizing fine-grained entry management (FGAC) with OpenSearch Service. If you use FGAC, you don’t have to make use of a website entry coverage; you possibly can skip the remainder of this part and proceed to creating your pipeline position with the mandatory permissions. For those who use a website entry coverage, you have to create a second coverage (for this put up, we name it write-to-opensearch) as an added step to the steps within the earlier part. Use the next coverage code:

{
	"Model": "2012-10-17",
	"Assertion": [
		{
			"Effect": "Allow",
			"Action": "es:DescribeDomain",
			"Resource": "arn:aws:es:*:{your-account-id}:domain/*"
		},
		{
			"Effect": "Allow",
			"Action": "es:ESHttp*",
			"Resource": "arn:aws:es:*:{your-account-id}:domain/{domain-name}/*"
		}
	]
}

If the configured position has permissions to entry Amazon S3 and Amazon SQS throughout accounts, OpenSearch Ingestion can ingest information throughout accounts.

Create the pipeline position with crucial permissions

Now that you’ve created the insurance policies, you possibly can create the pipeline position. Full the next steps:

1. On the IAM console, select Roles within the navigation pane.
2. Select Create position.
3. For Use circumstances for different AWS companies, choose OpenSearch Ingestion pipelines.
4. Select Subsequent.
5. Seek for and choose the coverage read-from-securitylake.
6. Seek for and choose the coverage write-to-opensearch (if you happen to’re utilizing a website entry coverage).
7. Select Subsequent.
8. For Position Title, enter pipeline-role.
9. Select Create.

Maintain notice of the position title; you’ll be utilizing it whereas configuring opensearch-pipeline.

Now you possibly can map the pipeline position to an OpenSearch backend position if you happen to’re utilizing FGAC. You’ll be able to map the ingestion position to one in every of predefined roles or create your individual with crucial permissions. For instance, all_access is a built-in position that grants administrative permission to all OpenSearch features. When deploying to a manufacturing surroundings, be certain to make use of a task with simply sufficient permissions to put in writing to your Amazon OpenSearch Service area.

Create the OpenSearch Ingestion pipeline

On this part, you utilize the pipeline position you created to create an OpenSearch Ingestion pipeline. Full the next steps:

2. Select Create pipeline.
3. For Pipeline title, enter a reputation, resembling security-lake-osi.
4. Within the Pipeline configuration part, select Configuration blueprints and select AWS-SecurityLakeS3ParquetOCSFPipeline.

5. Underneath supply, replace the next info:
   1. Replace the queue_url within the sqs part. (That is the SQS queue that Amazon Safety Lake created if you created a subscriber. To get the URL, navigate to the Amazon SQS console and search for the queue ARN created with the format AmazonSecurityLake-abcde-Principal-Queue.)
   2. Enter the Area to make use of for aws credentials.

6. Underneath sink, replace the next info:
   1. Substitute the hosts worth within the OpenSearch part with the Amazon OpenSearch Service area endpoint.
   2. For sts_role_arn, enter the ARN of pipeline-role.
   3. Set area as us-east-1.
   4. For index, enter the index title that was outlined within the template created within the earlier part ("ocsf-cuid-${/class_uid}-${/metadata/product/title}-${/class_name}-%{yyyy.MM.dd}").
7. Select Validate pipeline to confirm the pipeline configuration.

If the configuration is legitimate, a profitable validation message seems; now you can proceed to the subsequent steps.

8. Underneath Community, choose Public for this put up. Our advice is to pick VPC entry for an inherent layer of safety.
9. Select Subsequent.
10. Assessment the main points and create the pipeline.

When the pipeline is lively, it is best to see the safety information ingested into your Amazon OpenSearch Service area.
