API 101

Application program interface (API) is a set of routines, protocols, and tools for building software applications. An API specifies how software components should interact and APIs are used when programming graphical user interface (GUI) components. A good API makes it easier to develop a program by providing all the building blocks. A programmer then puts the blocks together" (webopedia, 2016).


Application Programming Interfaces allows applications to talk to other applications. For example:
  1.  Mobile devices all use APIs to connect our mobile app to Facebook.
  2. YouTube users consume videos using the universal embeddable video player (like Vimeo) allowing Youtube videos to be embedded on any website around the web, all driven by APIs.

SCM Software Configuration Management What? SCM is a software engineering discipline consisting of standard processes and techniques often used by organizations to manage the changes introduced to its software products. SCM helps to eliminate the confusion often caused by miscommunication among team members. The SCM system controls the basic components such as software objects, program code, test data, test output, design documents, and user manuals. Who? The Software Engineering Institute (SEI) advocated a standard definition for CM oriented to software, broadening the definition of the Institute of Electrical and Electronics Engineers (IEEE) and the guidelines of the International Organization for Standardization (ISO). Why? Is software engineering practices associated with software configuration management offer a number of opportunities to address requirements found International  Standard, ISO 9001. From management perspective, the principles and practices ...

Security Countermeasures and Denial of Service

" Denial of Service (DoS) and Distributed Denial of Service (DDoS) attacks impact system availability by flooding the target system with traffic or requests or by exploiting a system or software flaw" (PCcare, 2018). What happens during a DoS attack , is that a single attacker directs an attack against a single target, sending packets directly to the target. It basically targets the network bandwidth or connectivity. There are many common forms of DoS attacks , for example: Smurf Fraggle Ping flood Ping-of-death Syn Flood Land Teardrop DNS poisoning Banana Attack Negative Acknowledgement (NACK) Deuthentication (Deauth) One of the most knowledgeable and used is Spam . It consists of sending unwanted e-mail messages to users. It's considered a from of DoS because: It consumes bandwidth that is used by legitimate traffic.  It can fill a mailbox or hard disk and result in legitimate e-mail being rejected.  Spam is often distributed by hijacking misconfigured...

Reflection about Security and Privacy course

My experience with this course was a good one. I learned more theory about security and privacy than hands on learning, which  isn't a bad thing but i would've preferred some practice sessions with the Wizeline team on topics that could've helped us during the development of our project. My team and i had to really do some research on how to do 2FA with the technologies that we were using, we didn't have a guide line to get ourselves started. But as usual we managed to get it done. I think that including the Wizeline Security team really gave the course a plus. Taking this course really opened my eyes towards the Security aspect of software, because being a good programmer is so much more than just writing good code. It's about allowing yourself to explore every different angle of programming. The goal is to become a professional a multidimensional programmer and that's also my goal.  I believe that the goal of this course was to comprehend the impo...
