Hi and welcome to this posting! :D My name is Pedro Chaparro and I've been tutoring students for the last 3 years. I have a BSc in Computer Science and Engineering and I am currently studying for a MSc in Cyber Security at EPFL & ETH Zurich. I love to learn and help others. For instance, one of the ways I prepared for the Math National Exam was actually by being a tutor to friends who were having many doubts. You can learn more about me by visiting my website, chaparro.pt, or by reading my CV, cv.chaparro.pt. I would say my way of explaining is a bit different: I always try to keep people engaged and I don't stop until all the doubts are cleared! To explain something, I do it in a simple and intuitive way, and I like to come up with funny ways for people to understand the material. I also create a lot of drawings and figures to make it easier to understand! I take notes in a writing application and share them at the end of each class.

Trusted teacher: Objectives The program begins with an introductory level cybersecurity skills training, then progresses to advanced cybersecurity techniques such as reverse engineering, penetration testing techniques, and more. This training program will enable you to: • Implement technical strategies, tools, and techniques to secure data and information for your organization • Adhere to ethical security behavior to analyze and mitigate risks • Understand security in cloud computing architecture in depth • Understand legal requirements, privacy issues, and audit methodologies within a cloud environment • Focus on IT compliance and enterprise systems integrity to create a more secure enterprise IT framework what will you learn 1. Inactive survey conduct Attackers spend 70-80 percent of their time gathering information about their target. Doing so answers a lot of questions that saves them time during the activity. It makes sense that you as a security professional would do the same. In this module, Passive Survey Conducting, you will learn about effective untraceable data collection, referred to as a survey. First, you will see what information can be discovered about your target using public and open source information. Next, you'll discover what WHOIS, nslookup, and even Google can reveal about your target. Finally, you'll explore some of the apps designed to help automate this stage of the survey. Upon completion of this unit, you will have the skills and knowledge of passive reconnaissance needed to perform penetration testing. 2. Take an active survey So far, we've been "calm" about the survey. But the passive side is that we often don't see every system through passive ways. This was the active poll come to play. In this module, Conducting Active Reconnaissance, you will gain the ability to discover more network nodes and collect system information during penetration tests. First, you will learn how to discover all targets on a given network. Next, you will discover how to use enumeration to find services and even accounts on targets. Next, you'll see how to scan each point for vulnerabilities that could allow someone to gain unauthorized access to protected digital or electronic materials, and might get around routers or even firewalls to get in. Finally, you will explore how to research different types of scripts and some great tools to help automate your tasks. Upon completion of this course, you will have the skills and knowledge to discover many nodes, service accounts and even some of the vulnerabilities needed to cover every aspect of an active survey step in any pent-up engagement. 3. Gathering information and identifying weaknesses Now that you have identified, enumerated, and exposed vulnerabilities through both active and passive reconnaissance efforts, you need to know what to do with that data. In this module Gathering Information and Identifying Weaknesses, you will learn basic knowledge and gain the ability to analyze the weaknesses that you have discovered. First, you will learn how to choose the right vulnerability scanner, whether it is open source, commercial, on-premises or cloud-based. Next, you will discover how to organize said data by classifying assets, identifying false positives and preparing for judgment. Finally, you will explore how to turn this data into actionable exploits. Upon completion of this unit, you will possess the skills and knowledge to analyze vulnerabilities or command you to prepare for the next stage of the penetration testing lifecycle. 4. Application testing There are many different ways that software flaws can be exposed through design and implementation, so you will need to perform a variety of tests thoroughly to evaluate each application for which the company is responsible.
