How to strengthen the session security of the website, in view of this problem, this article introduces the corresponding analysis and answer in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible way.

In the website security protection, session session security is the current security protection, which must be securely deployed. Session is related to the entire user logging in to the website to interact with the website, and the session operation that data transmission has to be carried out. If session is hijacked, then the user account in the website will be maliciously logged in, and the login of the webmaster will also be hijacked, resulting in the website being hijacked, tampered with, redirected and so on. According to our SINE Security, when we deploy the security protection for customer websites, we find that most customer websites do not strengthen the session session state. For session security, we will share with you and explain to you so that more people know about website security.

What is a session website session?

To put it simply, when a user logs in to the website, a session value will be generated on the back-end server and recorded in the server, which is similar to the reason of cookies. Each user visiting the website will be assigned a separate session to the user, which is equivalent to marking the user. The normal session flow is: user access-establish session value-server data is transferred to the customer IP containing session. If the user does not have a session value, then the server will not connect to it and will not return any data to the user. Session id is independent.

The security problem that often occurs in session sessions in daily websites is that session is hijacked and attackers bypass session checks to get users' information directly. Some attackers even forge session to log on to the website and log on to any member account, and some advanced attackers will forge session to log in to the backstage of the website to obtain administrator rights.

Our SINE security often encounters that the customer's session is not released, causing the session to be available all the time. Attackers use the user's session to send malicious code to the server, or request some user operations, such as changing the user's password, withdrawing, data modification and so on. This is a session replay attack. The other is that after the visitor opens the website and does not have a login account password, he has already created a session value, which is also the same as its session value after the account is logged in, that is to say, a session value is called for both login and non-login status. If the website program does not do security verification and filtering in the design process, then it is very problematic. The attacker uses a session value to log in to the user account and obtain information. It may even lead to the disclosure of users' information.

So how to protect session session security of the website?

1. The session value after login is unique. Delete the session value previously written to the server after the account is logged out to prevent session from being available all the time.

two。 Security filtering of users' permissions is equivalent to the category of logical vulnerabilities. When session visits some pages with administrative rights, it compares the session of its current administrator account. If the session value is not the administrator's, then directly exit the page and return an error. If you do not know much about website security, it is recommended to find a professional website security company to deal with, domestic SINESAFE, Qiming Star, convinced, Green League is relatively good.

3. Set the effective time of session on the server side, such as setting the usage time of 12 hours, and delete it if the session exceeds 12 hours, so as to prevent attackers from using session sessions maliciously to hijack the attacking website.

4. Do two-way encryption verification to session, cooperate with cookies to encrypt, and decrypt the encrypted value to the server, so that the normal data communication can be carried out. The above is the security explanation and sharing of session session in website security protection. I also hope that this sharing of SINE security will let more and more people have an in-depth understanding of website security. Only when the website is secure can we ensure our information security and prevent the occurrence of user information disclosure.

This is the answer to the question about how to strengthen the session security of the website. I hope the above content can be of some help to you. If you still have a lot of doubts to be solved, you can follow the industry information channel to learn more about it.
