Musical notation is a set of symbols that we use to communicate the sounds we want a player to create on their instrument. It can be seen as the language of music and is core to understanding most topics in music theory. We will start this article by seeing…
A graph is a structure used to represent how two or more objects connect to each other. Many problems in the computer science realm use graph representation, and as such, many algorithms revolve around efficiently finding properties in graphs. …
A stack is a set of items stored using a last-in first-out or LIFO policy. This means that the last thing that is inserted to the stack is the first thing that is removed from the stack. Often, we might think of a stack like a stack of dinner plates…

The process of ethical hacking can be broken down into 5 main phases. These phases are:
1. Reconnaissance
2. Scanning
3. Gaining Access
4. Maintaining Access
5. Covering Tracks
In this article, I will walkthrough each of the phases to give a general overview of what each phase entails.
Phase…
In general, hackers can be divided into three general groups: white hats, black hats, and gray hats. White hats are ethical hackers, they use their skills to help defend a system from malicious users. Black hats are malicious hackers who use their skills for illegal or malicious purposes. Gray hats…
This article will explain to you the fundamentals of XXE vulnerabilities. When a server parses XML data provided by a user, there is a risk of XXE vulnerabilities. These vulnerabilities typically leverage external entities to expose sensitive information stored on the server. This is possible due to a feature…
