What is an example of ways to secure session management?

- Check for suspicious activity and immediately destroy any suspect session.
- Store all session information server-side, never store anything except the SID in the client-side cookie.
What is session management testing?
These mechanisms are known as Session Management. In this test, the tester wants to check that cookies and other session tokens are created in a secure and unpredictable way. An attacker who is able to predict and forge a weak cookie can easily hijack the sessions of legitimate users.

This is one of the reasons why cookies (RFCs 2109 & 2965 & 6265) are one of the most extensively used session ID exchange mechanisms, offering advanced capabilities not available in other methods.
What is session management in web applications?
Session management manages sessions between the web application and the users. The communication between a web browser and a website is usually done over HTTP or HTTPS.
