Understanding Session Hijacking

Session hijacking involves unauthorized access to an active user session, allowing attackers to impersonate the user and perform malicious activities. There are different methods used in session hijacking, including:

1. Session Sidejacking

Protecting Against Session Hijacking

Fortunately, there are several measures you can take to protect your online sessions from hijacking attempts:

1. Use HTTPS: Ensure that websites you visit use secure HTTPS connections to encrypt data exchanged between your browser and the server. Always check for the padlock icon in the address bar.
2.

This adds an extra layer of security to your login process.
3. Regularly Update Software: Keep your operating system, web browsers, and other software up to date. Updates often include security patches that address known vulnerabilities.
4. Be Cautious of Public Wi-Fi: Avoid accessing sensitive information, such as online banking, when connected to public Wi-Fi networks. If necessary, use a VPN (Virtual Private Network)E2E Encryption (End-to-End Encryption): A system of communic... to encrypt your traffic.

• Implement Session Expiration: Set session timeouts, forcing users to re-authenticate after a certain period of inactivity. This reduces the risk of session hijacking if a user forgets to log out.
• Implement CSRF Protection: Cross-Site Request Forgery (CSRF) attacks exploit session information to execute unauthorized actions. Implement mechanisms like CSRF tokens to prevent such attacks.
• Employ Transport Layer Security (TLS)Public Key Infrastructure (PKI): A framework that manages di...: Use TLS protocols to encrypt data transmitted between clients and servers, preventing eavesdropping and tampering.
