HTTP Security

HTTP Security refers to the principles, practices, and mechanisms used to protect data transmitted over the Hypertext Transfer Protocol (HTTP) from unauthorized access, tampering, or interception. It encompasses a range of techniques including encryption, authentication, and authorization to ensure the confidentiality, integrity, and availability of web communications. This is fundamental for securing web applications, APIs, and online services against common threats like man-in-the-middle attacks, data breaches, and session hijacking.

Why learn HTTP Security?

Developers should learn HTTP Security to build secure web applications that protect sensitive user data, such as passwords, personal information, and financial details, from cyber threats. It is essential for compliance with regulations like GDPR and PCI-DSS, and for preventing vulnerabilities like cross-site scripting (XSS) and SQL injection in client-server interactions. Use cases include implementing HTTPS for encrypted connections, setting secure cookies, and using headers like Content-Security-Policy to mitigate risks in modern web development.
