In this series of posts about Security in IoT, I try to clarify the following questions: Is our IoT devices secure enough against different attacks and how we can measure it? How can we improve it? What are the most common backdoors in IoT devices? How we can detect the vulnerability of IoT devices? What

Adding user Sign-in of AWS Cognito to Android app is relatively easy, so this post would be short and easy to follow. Before adding authentication to the project, we should add some prerequisites to our Android project. Basically, there are three prerequisites for each Android app which wants to connect to communicate with AWS. These

RTT is the length of time it takes for a signal to be sent plus the length of time it takes for an acknowledgment of that signal to be received [1]. In other words, a small packet will be sent to a specific computer and it will send the packet back, the time difference between

According to Wikipedia, Edge Computing is a method of optimizing applications or cloud computing systems by taking some portion of an application, its data, or services away from one or more central nodes (the “core”) to the other logical extreme (the “edge”) of the Internet which makes contact with the physical world or end users

In part I, I’ve described Serverless Computing in detail with an example. In this post, I’ll start by describing serverless platforms and toolkits and continue with comparing some of them to each other. B. Serverless Platform Cloud providers offer Serverless platforms which are ready to develop and deploy a serverless application. Most popular platforms are

Serverless computing is changing the way of computation in the cloud and even in the network edges. Companies are spending time and money to maintain their servers and related software in order to make their business application up and running for their users. Traditional server-based computation slows down companies to go to the market which
