Managing Amazon GuardDuty Security Findings Across Multiple Accounts


Managing Amazon GuardDuty Security Findings Across Multiple Accounts In our previous article, we discussed how GuardDuty can help organizations monitor their workloads and  AWS accounts from malicious activities and how to monitor findings with Amazon CloudWatch Events. Imagine that your organization has multiple AWS accounts for different workloads, teams, and projects. With every account, you need to monitor GuardDuty findings individually. It will be quite difficult for your security team to monitor these findings with their constant switching between AWS accounts.  Amazon GuardDuty supports the consolidation of these findings to one AWS account. For example, your organization has 10 AWS [...]

AWS Secrets Manager vs Systems Manager Parameter Store


AWS Secrets Manager vs Systems Manager Parameter Store Managing the security of your applications is an integral part of any organization especially for infrastructures deployed in the cloud. One aspect of application security is how the parameters such as environment variables, database passwords, API keys, product keys, etc. are stored and retrieved. As a best practice, secret information should not be stored in plain text and not be embedded inside your source code. It is also recommended to set up an automated system to rotate passwords or keys regularly (which is easy to forget when you manage keys manually). Managing [...]

Global Secondary Index vs Local Secondary Index


Global Secondary Index vs Local Secondary Index A secondary index is a data structure that contains a subset of attributes from a table, along with an alternate key to support Query operations. An Amazon DynamoDB table can have multiple secondary indexes. Global Secondary Index Read/Write Capacity Calculation (Provisioned Throughput Mode) Eventually consistent reads consume ½ read capacity unit. Therefore, each query can retrieve up to 8KB of data per capacity unit (4KB x 2). The maximum size of the results returned by a Query operation is 1 MB. The total provisioned throughput cost for a write consists of the sum [...]

AWS Global Accelerator vs Amazon CloudFront


AWS Global Accelerator vs Amazon CloudFront In this day and age, your site speed performance is an important factor when it comes to user experience. It is widely recommended for websites to have an average load time of 3 seconds as users tend to abandon the site if a page takes longer than 3 seconds to load. According to Amazon, just 100 milliseconds of extra load time cost them 1% in sales. Indeed, every second counts in our fast-paced digital world. Amazon Web Services has always been the global leader in Cloud Computing with its speed, performance, and reliability. With [...]

AWS CodeCommit Repository


AWS CodeCommit Repository Amazon Web Services, with its ever-growing breadth of services, offers a fully-managed version control system where developers can privately store their application source code like Github or Bitbucket. CodeCommit can be used as a staging ground coupled with CodeDeploy and CodePipeline to seamlessly deploy code to Amazon EC2 instances.  In this article, I will discuss how we can leverage Amazon SNS to send notifications whenever there are events in our repository. This is particularly useful when we need to keep our work colleagues up-to-date if there are events in our repository. Triggers are used for two things. [...]

Amazon Cognito User Pools vs Identity Pools


Amazon Cognito User Pools vs Identity Pools With the proliferation of smartphones in our connected world, more and more developers are quickly deploying their applications on the cloud.

There are multiple stages involved in user verification and most of these are not visible from the end-user. AWS provides an easy solution for this situation. User Identity verification is at the core of Amazon Cognito. It provides solutions for three key areas of user identification:  Authentication – provides users sign-up and sign-in [...]
