In this module, we will delve into various security vulnerabilities that can affect .NET Core applications. You'll learn about SQL injection, cross-site scripting (XSS), and cross-site request forgery (CSRF) attacks, understanding how they occur and how to prevent them. We will also explore directory traversal, unvalidated redirects, session hijacking, parameter manipulation, and security misconfigurations. Additionally, you’ll discover the risks associated with file uploads and insecure cryptographic storage. By the end of this module, you will have hands-on experience with these vulnerabilities, equipping you with the skills to safeguard your applications against potential threats.

In this module, we will explore various mitigation strategies to fortify your .NET Core applications against sophisticated cyber-attacks. You'll learn how to secure user inputs, handle file uploads safely, and implement protection against CSRF and XSS attacks. We will delve into the nuances of serialization and deserialization, the importance of security headers, and the implementation of CAPTCHA. Additionally, we will cover best practices for authentication, secure data access, and storage. Finally, you'll gain hands-on experience by applying mitigation techniques to various vulnerabilities, ensuring your code is both functional and secure.

In this module, we will delve into the essential aspects of cryptography, starting with an overview of its history and evolution. You'll explore the fundamentals of symmetric encryption and various ciphers, followed by an in-depth look at asymmetric encryption and the mathematical principles behind the RSA Cryptosystem. Additionally, we will cover hashing techniques and the critical importance of digital signatures in cybersecurity. By understanding these cryptographic concepts, you will be able to implement secure encryption and hashing mechanisms in your .NET Core applications, ensuring robust protection of sensitive data.
