• 400 Bad Request Errors: When a client's request cannot be processed due to an invalid or unsupported response from the server.
• HTTPS Connections: Secure Hypertext Transfer Protocol, often abbreviated as HTTPS, uses encryption and a secure connection to ensure data confidentiality and integrity. However, this security is compromised when the "400 Bad Request" error occurs, indicating that the request cannot be processed due to an invalid or unsupported response from the server.
• Vulnerabilities of HTTPS: The use of self-signed certificates, lack of SSL/TLS version 1.0 support, and insufficient firewall rules can leave a web application vulnerable to man-in-the-middle attacks, data exfiltration, and other security threats when it sends HTTP requests over HTTPS.
• Case Study: A hypothetical example illustrating the consequences of a "400 Bad Request" error in an online banking system that uses HTTPS for all transactions. The article would demonstrate how the error could lead to financial losses due to stolen user credentials or unauthorized access to sensitive information.
