Creating data protection policies to secure message data (SDK)

The number and size of Amazon SNS resources in an Amazon account are limited. For more information, see Amazon Simple Notification Service endpoints and quotas.

Creating data protection policies (Amazon SDK)

You can create an Amazon SNS data protection policy using the Amazon SDK.

To create a data protection policy together with an Amazon SNS topic (Amazon SDK)

Use the following options to create a new data protection policy together with a standard Amazon SNS topic:

Java
/**
 * For information regarding CreateTopic see this documentation topic:
 *
 * https://docs.aws.amazon.com/code-samples/latest/catalog/javav2-sns-src-main-java-com-example-sns-CreateTopic.java.html
 */

public static String createSNSTopicWithDataProtectionPolicy(SnsClient snsClient, String topicName, String dataProtectionPolicy) {

    try {
        CreateTopicRequest request = CreateTopicRequest.builder()
                .name(topicName)
                .dataProtectionPolicy(dataProtectionPolicy)
                .build();

        CreateTopicResponse result = snsClient.createTopic(request);
        return result.topicArn();
    } catch (SnsException e) {
        System.err.println(e.awsErrorDetails().errorMessage());
        System.exit(1);
    }
    return "";
}
JavaScript
// Import required AWS SDK clients and commands for Node.js
import {CreateTopicCommand } from "@aws-sdk/client-sns";
import {snsClient } from "./libs/snsClient.js";

// Set the parameters
const params = { Name: "TOPIC_NAME", DataProtectionPolicy: "DATA_PROTECTION_POLICY" };

const run = async () => {
  try {
    const data = await snsClient.send(new CreateTopicCommand(params));
    console.log("Success.",  data);
    return data; // For unit tests.
  } catch (err) {
    console.log("Error", err.stack);
  }
};
run();
To create or retrieve a data protection policy for an existing Amazon SNS topic (Amazon SDK)

Use the following options to create or retrieve a new data protection policy together with a standard Amazon SNS topic:

Java

public static void putDataProtectionPolicy(SnsClient snsClient, String topicName, String dataProtectionPolicy) {

    try {
        PutDataProtectionPolicyRequest request = PutDataProtectionPolicyRequest.builder()
                .resourceArn(topicName)
                .dataProtectionPolicy(dataProtectionPolicy)
                .build();

        PutDataProtectionPolicyResponse result = snsClient.putDataProtectionPolicy(request);
        System.out.println("\n\nStatus was " + result.sdkHttpResponse().statusCode() 
                + "\n\nTopic " + request.resourceArn()
                + " DataProtectionPolicy " + request.dataProtectionPolicy());
    } catch (SnsException e) {
        System.err.println(e.awsErrorDetails().errorMessage());
        System.exit(1);
    }
}


public static void getDataProtectionPolicy(SnsClient snsClient, String topicName) {

    try {
        GetDataProtectionPolicyRequest request = GetDataProtectionPolicyRequest.builder()
                .resourceArn(topicName)
                .build();
        
        GetDataProtectionPolicyResponse result = snsClient.getDataProtectionPolicy(request);
        
        System.out.println("\n\nStatus is " + result.sdkHttpResponse().statusCode() 
        + "\n\nDataProtectionPolicy: \n\n" + result.dataProtectionPolicy());
    } catch (SnsException e) {
        System.err.println(e.awsErrorDetails().errorMessage());
        System.exit(1);
    }
}
JavaScript
// Import required AWS SDK clients and commands for Node.js
import {PutDataProtectionPolicyCommand, GetDataProtectionPolicyCommand } from "@aws-sdk/client-sns";
import {snsClient } from "./libs/snsClient.js";

// Set the parameters
const putParams = { ResourceArn: "TOPIC_ARN", DataProtectionPolicy: "DATA_PROTECTION_POLICY" };

const runPut = async () => {
  try {
    const data = await snsClient.send(new PutDataProtectionPolicyCommand(putParams));
    console.log("Success.",  data);
    return data; // For unit tests.
  } catch (err) {
    console.log("Error", err.stack);
  }
};
runPut();

// Set the parameters
const getParams = { ResourceArn: "TOPIC_ARN" };

const runGet = async () => {
  try {
    const data = await snsClient.send(new GetDataProtectionPolicyCommand(getParams));
    console.log("Success.",  data);
    return data; // For unit tests.
  } catch (err) {
    console.log("Error", err.stack);
  }
};
runGet();
