Set up templates and dashboards for Amazon Safety Lake knowledge

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

Index templates are predefined mappings for safety knowledge that selects the proper OpenSearch discipline varieties 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 knowledge 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) Circulate 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 establish OpenSearch indices containing Safety Lake knowledge, we suggest 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

Configure OpenSearch Ingestion

Every OpenSearch Ingestion pipeline may have a single knowledge 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 organising OpenSearch Ingestion, it’s worthwhile to create the next IAM roles and arrange the required permissions:

• Pipeline function – Defines permissions to learn from Amazon Safety Lake and write to the OpenSearch Service area
• Administration function – Defines permission to permit the person 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 providers.

Earlier than you create an OpenSearch Ingestion pipeline, the principal or the person creating the pipeline will need to have permissions to carry out administration actions on a pipeline (create, replace, listing, and validate). Moreover, the principal will need to have permission to cross the pipeline function to OpenSearch Ingestion. In case you are performing these operations as a non-administrator, add the next permissions to the person creating the pipelines:

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

Configure a learn coverage for the pipeline function

Safety Lake subscribers solely have entry to the supply knowledge within the Area you chose whenever you created the subscriber. To offer a subscriber entry to knowledge from a number of Areas, confer 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 function:

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

3. Make a remark of this Amazon S3 bucket title.

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

6. Be aware of the Amazon SQS queue ARN underneath 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 (change 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": "Exchange {your-account-id} along 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 have got efficiently created the coverage to learn knowledge 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 function

We suggest utilizing fine-grained entry management (FGAC) with OpenSearch Service. Whenever you use FGAC, you don’t have to make use of a website entry coverage; you’ll be able to skip the remainder of this part and proceed to creating your pipeline function with the mandatory permissions. For those who use a website entry coverage, it’s worthwhile 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 function has permissions to entry Amazon S3 and Amazon SQS throughout accounts, OpenSearch Ingestion can ingest knowledge throughout accounts.

Create the pipeline function with mandatory permissions

Now that you’ve got created the insurance policies, you’ll be able to create the pipeline function. Full the next steps:

1. On the IAM console, select Roles within the navigation pane.
2. Select Create function.
3. For Use circumstances for different AWS providers, 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 (for those who’re utilizing a website entry coverage).
7. Select Subsequent.
8. For Position Title, enter pipeline-role.
9. Select Create.

Preserve word of the function title; you’ll be utilizing it whereas configuring opensearch-pipeline.

Now you’ll be able to map the pipeline function to an OpenSearch backend function for those who’re utilizing FGAC. You possibly can map the ingestion function to considered one of predefined roles or create your personal with mandatory permissions. For instance, all_access is a built-in function that grants administrative permission to all OpenSearch features. When deploying to a manufacturing setting, be certain that to make use of a job 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 function you created to create an OpenSearch Ingestion pipeline. Full the next steps:

1. On the OpenSearch Service console, select OpenSearch Ingestion within the navigation pane.
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. Beneath supply, replace the next data:
   1. Replace the queue_url within the sqs part. (That is the SQS queue that Amazon Safety Lake created whenever 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-Most important-Queue.)
   2. Enter the Area to make use of for aws credentials.

6. Beneath sink, replace the next data:
   1. Exchange 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. Beneath Community, choose Public for this put up. Our suggestion is to pick VPC entry for an inherent layer of safety.
9. Select Subsequent.
10. Evaluate the small print and create the pipeline.

When the pipeline is lively, you must see the safety knowledge ingested into your Amazon OpenSearch Service area.

Visualize the safety knowledge

After OpenSearch Ingestion begins writing your knowledge into your OpenSearch Service area, you must be capable to visualize the info utilizing the pre-built dashboards you imported earlier. Navigate to dashboards and select any one of many put in dashboards.

For instance, selecting DNS Exercise gives you dashboards of all DNS exercise revealed in Amazon Safety Lake.

This dashboard reveals the highest DNS queries by account and hostname. It additionally reveals the variety of queries per account. OpenSearch Dashboards are versatile; you’ll be able to add, delete, or replace any of those visualizations to fit your group and enterprise wants.

Clear up

To keep away from undesirable prices, delete the OpenSearch Service area and OpenSearch Ingestion pipeline, and disable Amazon Safety Lake.
