This helps to prevent SQL injection attacks, which can be used to execute malicious code on the server. - **Parameterization:** ASP.NET uses parameterization to prevent SQL injection attacks. Parameterization involves using placeholders for user input in database queries. This prevents attackers from injecting malicious code into the query, which can then be executed on the server. - **Output encoding:** ASP.NET uses output encoding to prevent XSS attacks. Output encoding converts special characters into HTML entities, which prevents them from being interpreted as HTML code by the user's browser. This helps to prevent attackers from injecting malicious code into web pages, which can then be executed by the user's browser. - **Data encryption:** ASP.NET can be used to encrypt data before it is stored in a database or transmitted over a network. This helps to protect data from unauthorized access. In addition to these security features, ASP.NET also provides a number of other security features, such as: - **Role-based security:** ASP.NET can be used to implement role-based security, which allows you to control who has access to different resources on your web application. - **Session management:** ASP.NET can be used to implement session management, which allows you to track users as they navigate through your web application. This can be used to improve the user experience and to prevent unauthorized access to resources. - **Web application firewalls:** ASP.NET can be used with a web application firewall (WAF) to provide additional protection against a variety of attacks, including SQL injection, XSS, and denial-of-service attacks. By using these security features, ASP.NET can help to protect your web application from a variety of attacks. However, it is important to note that no security system is perfect. It is important to implement security best practices and to regularly monitor your web application for signs of attack. --- Original Source: https://www.mindstick.com/forum/157784/how-does-asp-dot-net-protect-against-attacks-such-as-sql-injection-and-xss-when-encrypting-data Copyright © MindStick Software Pvt.
