Cross-site Request Forgery Protection in web applications via  Double Submit Cookies Pattern What is Cross-site Request Forgery Protection(CSRF)? This is a kind of attack and type of a malicious exploit of a website. We also name this attack as the one-click attack or session riding. This forces an end user to execute unwanted actions on a web application in which they're currently authenticated. This attack is mainly focusing on state-changing request, not theft data.

Internet of Things What is Internet of Things? Simply put, this is the concept of basically connecting any device with an on and off switch to the Internet (and/or to each other). This includes everything from cellphones, coffee makers, washing machines, headphones, lamps, wearable devices and almost anything else you can think of. This also applies to components of machines, for example a jet engine of an airplane or the drill of an oil rig. As I mentioned, if it has an on and off switch then chances are it can be a part of the IoT. The analyst firm Gartner says that by 2020 there will be over 26 billion connected devices... That's a lot of connections (some even estimate this number to be much higher, over 100 billion). The IoT is a giant network of connected "things" (which also includes people). The relationship will be between people-people, people-things, and things-things. Key Components of IoT? 1. Sensors & Actuators : Inputs/Outputs ...

Usage of Cloud Computing 1. Infrastructure as a service (IaaS) and platform as a service (PaaS)   When it comes to IaaS, using an existing infrastructure on a pay-per-use scheme seems to be an obvious choice for companies saving on the cost of investing to acquire, manage and maintain an IT infrastructure. There are also instances where organizations turn to PaaS for the same reasons while also seeking to increase the speed of development on a ready-to-use platform to deploy applications. 2. Priva...
