Web Security and Privacy

Web Security and Privacy is a critical sub-discipline of cybersecurity focused on protecting web applications, servers, and user data from a wide range of online threats. It encompasses the practice of defending web infrastructure from attacks such as SQL injection and Cross-Site Scripting (XSS) to ensure service integrity and availability, while also safeguarding user privacy by preventing the unauthorized access, tracking, or misuse of personal data. Key techniques involve implementing secure coding practices, conducting vulnerability assessments, and utilizing cryptographic protocols like HTTPS to create a trustworthy and safe online environment for both businesses and their users.
