AWS - Data Protection with SNS

-

 

Amazon Simple Notification Service (Amazon SNS) sends notifications two ways, A2A and A2P.

A2A provides high-throughput, push-based, many-to-many messaging between distributed systems, microservices, and event-driven serverless applications. 

These applications include Amazon Simple Queue Service (SQS), Amazon Kinesis Data Firehose, AWS Lambda, and other HTTPS endpoints. A2P functionality lets you send messages to your customers with SMS texts, push notifications, and email. 

In this post, we will see how to protect sensitive data from being sent to the endpoints.

We already have a TOPIC and EMAIL subscription in place.

Let's test it by sending a message with a US mobile number.


And we got the message.


Let's create a "Data Protection Policy" with DENY for USA Mobile Numbers.

Edit the TOPIC.


The Deny Statement has predefined Data Identifiers like Phone numbers and others. In the above statement, I have added a DENY for PHONE NUMBER US.

DENY DIRECTION can be INBOUND and OUTBOUND.

INBOUND -> DENY messages coming to the SNS.

OUTBOUND -> DENY messages sent to the endpoint (Email).

So, If I publish the same message it will not be sent. If Cloudwatch is configured (Audit) you will see a log for the same.

AWS Code Commit - CI/CD Series Part 1

  This is a multi-part series to show how to implement a CI/CD pipeline in AWS. In this post, We will see how to use AWS Code Commit. AWS CodeCommit is a fully managed source control service that allows you to store and manage your code securely in the cloud.  It provides a private Git repository for your code and supports all Git commands and workflows. CodeCommit also integrates with other AWS services like AWS CodePipeline and AWS CodeBuild, allowing you to automate your entire software release process. This can help you streamline your development workflows and improve the overall efficiency of your team. I created a repo from AWS CodeCommit -> Create Repository. And I begin with cloning the repo locally. So that I can make changes and push it. To clone the repo click on "HTTPS" under Clone URL. I make changes to index.html file. Now push it to AWS CodeCommit. Let’s verify the changes in AWS Code commit. Changes are reflected in AWS CodeCommit. We are done with Part ...

Docker - Preventing IP overlapping

  What is IP address overlapping? When the container IP address overlaps with another IP external, then the application running on the container is not accessible from outside due to the IP address overlapping.  NOTE: This IP address overlapping can happen on the bridge interface IP or docker container IP. Let's see how to address this IP overlapping issue on the bridge interface. I already have a running container.  root@demo:~# docker run -d --name web --network mynet1 nginx:alpine 268647e11011d513d2357ce1c81e0f48787038a83d01d028d31a5b29dbdb885b root@demo:~# docker container ls CONTAINER ID   IMAGE          COMMAND                  CREATED         STATUS         PORTS     NAMES 268647e11011   nginx:alpine   "/docker-entrypoint.…"   4 seconds ago   Up 3 seconds   80/tcp  ...
