Ethical Hacking and Penetration Testing Basics Ethical hacking is the practice of testing a computer system, network, or application with permission to find security weaknesses before bad actors do. Penetration testing is a structured form of this work that follows a plan, uses real-world techniques, and produces practical fixes. The aim is to improve security without disrupting daily operations. To stay within the law and protect people’s privacy, always get written authorization and define the test scope. A good test respects data, limits access, and logs every action. Before you begin, agree on goals, time frames, and what kind of report the client will receive. ...

Getting Started with Virtualization and Containerization Virtualization and containerization help you run software in safe, isolated spaces. Virtualization uses a hypervisor to create full virtual machines, each with its own operating system. Containerization uses the host OS kernel and runs apps in lightweight containers. Both methods give you clean environments for testing, learning, and deploying software. Starting out is easier than it looks. Decide your goal: do you want to study how machines behave, or do you want to package apps for reliable deployment? If you need complete OS diversity and strong isolation, virtualization is the way. If you want fast startup, small size, and easy sharing, containers are ideal. ...
