Python is a versatile language and is used in general-purpose applications as well as in specific use cases. Since the creation of Python, it has been used in various applications and use cases by software developers and researchers alike. These applications include system-level applications, APIs (Application Programming Interfaces), e-commerce applications, database applications, and, more recently, data science and cybersecurity applications. In this book, you will get an in-depth understanding of writing Python code for solving simple to moderate complexity problems in cybersecurity. We will start with simple problems in reconnaissance and then slowly experiment with advanced cybersecurity techniques in forensics analysis or cyber forensics, penetration testing, malware analysis, and many more such areas. After completing this book, the readers will be confident in solving problems and creating solutions. They should also be able to work as cybersecurity professionals. The readers will benefit from this book's hands-on knowledge and activities, irrespective of their current level.
