Previous Question Next Question

To secure user sessions and prevent hijacking attacks, you should implement secure session management practices such as using HTTPS, setting secure cookies, and implementing proper session expiration.

<!-- BEGIN COPY / PASTE -->
    // Example of setting a secure session cookie in Express.js
    app.use(session({
      secret: 'your-secret-key',
      resave: false,
      saveUninitialized: true,
      cookie: {
        httpOnly: true, // Prevents client-side scripts from accessing the cookie
        secure: true,   // Ensures the cookie is sent over HTTPS only
        maxAge: 60000   // Sets session expiration time
      }
    }));
    <!-- END COPY / PASTE -->

Additional Comment:

Always use HTTPS to encrypt data in transit, protecting session cookies from being intercepted.
Set the httpOnly flag on cookies to prevent JavaScript access, mitigating XSS attacks.
Implement session expiration and regeneration to reduce the risk of session fixation.
