Acquiring the necessary skills to protect digital systems and secure sensitive information has become more crucial than ever. That’s why we present to you the course "Basics of System hacking and Penetration Testing" which provides you with a comprehensive and practical understanding of penetration testing and the basics of cybersecurity, enabling you to identify and effectively address system vulnerabilities. The course begins by explaining hacking techniques and password cracking fundamentals, starting with theoretical concepts to understand how encryption and protection techniques work, and moving on to applying practical strategies for password cracking. This helps you grasp how to strengthen password security. Additionally, you will learn about Steganography techniques and Covering Tracks— essential tools for ethical hacking to ensure these activities remain undetected during testing operations. The course also includes an in-depth study of malware such as viruses, Trojans, and worms, along with how to design and use these in testing environments. Furthermore, you will gain hands-on experience in network attacks like eavesdropping, ARP poisoning, and Denial-of-Service (DoS) attacks, with practice in virtual environments that simulate real-world scenarios. To deepen your understanding of defensive systems, the course covers Intrusion Detection Systems (IDS), Intrusion Prevention Systems (IPS), firewalls, and honeypots. You will also learn bypassing strategies and detection methods, equipping you to analyze and evaluate the security architecture of any system. By the end of the course, you will be equipped with the foundational knowledge and skills that prepare you to confidently enter the field of cybersecurity.
