In my previous post, we learnt about how to launch RDS Aurora instance. The storage space of RDS Aurora is automatically scalable up to 64 TB and the read scaling can be achieved by creating up to 15 replicas in the cluster. I had migrated database into RDS Aurora to avail fault tolerance feature. Once the migration was completed I came...
Encrypting RDS provides additional security by encrypting the underlying storage of your RDS data. Amazon uses AES-256 encryption algorithm to encrypt your RDS data on the devices on the servers hosting your database instances.The performance impact of the encryption is minimal on your DB instance. Your end application does not require...

We have seen a lot of applications where some sub-domains or sub-directories are publicly exposed (intently or by mistake). So, with experience from our past pentests we have made a habit of testing for vulnerable or accessible sub-domains. During one of such testing, I was manually testing the URLs of different sub-domains of the...
In my last couple of blogs, I talked about Docker monitoring, why I would need Docker monitoring and how I can monitor Docker containers using AWS, Ruxit and Sysdig. Today, we are going to talk about another such tool which most of us already know about which also provides Docker monitoring. The tool is New Relic. How to...
Recently, I worked on a task wherein the users had to be authenticated based on existing Google credentials to get access of AWS Management Console. It took more time than expected to make it work as the documentation provided by Google is not complete. Let’s start by setting this up step by step. Scenario: Provide access of AWS...
