Symmetric vs. Asymmetric CMKs

2021-03-16T00:34:11+00:00

Even before the Internet, the security, privacy, and integrity of information have always been the top concern of institutions like banks, hospitals, and universities. Nobody wants their personal information (name, address, credit card number, etc.) to be exposed in public for anyone to use. Imagine signing up on your favorite social media website, and after a few days, somewhere on the globe has been using your profile and pretending to be you without you knowing! Or maybe you’ve been using your credit card for shopping online and suddenly, your bank is sending you email reports for fraudulent activities on your [...]

AWS Managed Policies For Job Functions

2021-04-08T08:19:27+00:00

AWS managed policies for job functions are policies that contain sets  of permissions required for a specific job function or role (especially in the IT industry). It is designed to simplify the creation of policies by combining the permissions for many services into a single policy. You can attach these policies for job functions to any group, user, or role.  To further understand this, let’s consider the scenario below: Mikee is the new database administrator of a social media startup that leverages on Amazon Web Services. She was assigned to configure the minimum set of permissions in IAM so she [...]

Amazon Aurora Machine Learning

2021-04-08T08:36:08+00:00

Amazon Aurora Machine Learning is a proprietary technology of Amazon that enables a native SQL user to integrate Machine Learning-based predictions to an application without knowing or understanding any machine learning algorithms. Machine learning heavily relies on datasets for it to work. You can say that data is the oil that keeps the engine of machine learning running. There is a massive amount of data generated every day. To give you an idea, according to this article, “By 2020, it’s estimated that for every person on earth, 1.7 MB of data will be created every second.”  Almost 2 MB of [...]
