Data Science Practice Test for Interviews & Exams 2025

Penetration Test, atau yang sering disebut sebagai “Pentest,” adalah uji keamanan yang dilakukan dengan meluncurkan serangan siber simulasi untuk menemukan kerentanan dalam sistem komputer. Para penetration tester adalah profesional keamanan yang terampil dalam seni peretasan etis, yaitu penggunaan alat dan teknik peretasan untuk memperbaiki kelemahan keamanan daripada menyebabkan kerusakan. Perusahaan mempekerjakan pen tester untuk meluncurkan serangan simulasi terhadap aplikasi, jaringan, dan aset lainnya. Dengan melakukan serangan palsu ini, pentester membantu tim keamanan mengungkap kerentanan keamanan kritis dan meningkatkan postur keamanan secara keseluruhan. Jadi, Pentest ini merupakan kegiatan yang sangat penting untuk mengidentifikasi dan memperbaiki kerentanan sebelum penyerang yang sebenarnya memanfaatkannya.Course ini akan mengajarkan langkah-langkah proses Penetration Test, dan untuk lebih spesifiknya kita akan mencari kelemahan pada platform Joomla. Joomla adalah platform pembuatan situs web yang bersifat open-source. Secara teknis, Joomla adalah sistem manajemen konten (CMS) yang ditulis dalam bahasa PHP dan menggunakan basis data MySQL/MariaDB. Dalam bahasa yang lebih sederhana, Joomla adalah alat pembuat blog dan situs web banyak digemari saat ini.Namun seringkali kita melihat situs-situs penting yang menggunakan Joomla dirusak oleh Hacker. Misalnya dilakukan defacing maupun ditanamkan sebuah halaman sebagai iklan slot gacor. Nah, kenapa situs Joomla ini bisa dihack padahal Joomla ini merupakan platform yang sangat banyak digunakan didunia?Course ini akan melakukan pembahasan mulai dari Information Gathering, Directory Enumeration, Eksploitasi, SSRF, Gopher, Libcurl, menanam Webshell reverse TCP, proses privilege escalation, mendapatkan hak akses root hingga bagaimana menanam backdoor. Metode untuk eksploitasi lab kali ini lebih rumit dan lebih panjang dari lab Easy - Medium sebelumnya. Kemudian akan ada materi tambahan khusus dimana kita akan melakukan debugging vulnerabl

You've built technically perfect features. That nobody used.You spent months in sprints. Only to discover you solved the wrong problem. Research shows that 45% of product features go completely unused—not because of poor code, but because teams build solutions before understanding the real human need.Design Thinking was supposed to prevent this. But for developers and engineers, the traditional process feels painfully disconnected: endless workshopsabstract sticky-note exercisesand frameworks that don't fit into your sprint cycles.There's a better way.This course shows you how to run the complete Design Thinking process at the speed of your development workflow—using AI as your research team, ideation partner, and prototyping assistant.How you will learn:Forget theory and fluff. You'll build three real-world projects that prove the methodology works:Project 1: B2C FinTech AppDesign a concept for a personal finance dashboard that builds user trust and makes complex financial data instantly understandable. You'll go from raw user pain points to a tested, high-fidelity prototype in under 6 hours.Project 2: B2B Sales Co-PilotIdeate and test an internal tool that sales teams will actually use.Learn to map existing workflows, identify friction points, and prototype solutions that integrate seamlessly into business processes—not disrupt them.Project 3: MVP Concept Accelerator (a tool you will still be using AFTER completing the course)Build the ultimate meta-tool: a reusable AI-powered system that takes any product idea and outputs validated personas, problem statements, feature concepts, and wireframes in 20 minutes. Use it for every future proj
