The deployment of the SSL certificate is conducive to protecting the security between users and websites. What are the precautions after using the SSL certificate? Use the SSL certificate correctly and safely to ensure the security and smooth operation of the website. Common SSL certificates use precautions as follows!

　　1. The credible source of the certificate:

　　Use the SSL certificate obtained from a trusted certificate issuing agency (CA). Trust CA will verify your identity to ensure that your certificate is trusted in the browser. Do not use self -signed certificates because they will cause unsafe warnings in the browser.

　　2. Validity period of certificates:

　　Check and update the SSL certificate to ensure that the validity period will not expire. Expired certificates will cause browsers to display security warnings, and may also affect the availability of the site.

　　Third, private key security:

　　Make sure your SSL private key is stored in a safe position, and only trusted persons can access it. Private key leaks may lead to failure and security vulnerabilities.

　　Fourth, security protocol and encryption algorithm:

　　The configuration server uses powerful security protocols and encryption algorithms, such as TLS 1.2 or TLS 1.3, and avoid using weak passwords and encryption algorithms, such as SSL 2.0 and SSL 3.0.

　　Five, integrity protection:

　　Use the SSL certificate to ensure the integrity of the data. The SSL certificate can prevent data from being tampered or stolen during transmission.

　　6. Mixed content:

　　Avoid non -encryption (HTTP) content on the webpage of SSL, because this may trigger a security warning of the browser. Make sure that everything is provided through HTTPS.

　　Seven, certificate chain verification:

　　Make sure the server is configured correctly to verify the validity of the certificate chain. The browser will check whether the certificate is issued by the trusted CA and whether it is completely effective.

　　8. Domain name matching:

　　Make sure the SSL certificate matches your domain name. Do not reuse certificates on different domain names because this may lead to security issues.

　　Nine, SSL re -negotiated attack:

　　Take necessary security measures for SSL re -negotiating attacks. This attack may lead to the insecurity of the SSL connection.

　　10. The use of public Wi-Fi:

　　Use SSL on the public Wi-Fi network to ensure the security transmission of data. Public Wi-Fi networks are vulnerable to intermediate attacks. Using SSL can protect data from monitoring and stealing.

　　11. Monitoring and log:

　　Regularly monitor the status of the SSL certificate and the security of the server, and record security incidents for audit and investigation.

　　12. SSL certificate renewal:

　　Plan the renewal process of the SSL certificate in advance to avoid interruption caused by the expiration of the certificate.

　　13. HTTPS compulsory:

　　Using HTTPS for compulsory, setting the website or HTTP header through the website to ensure that all access is carried out by encryption.

　　In the process of using the SSL certificate, pay attention to the above thirteen points, which will help ensure the correct configuration and effective use of the SSL certificate, and further improve the security and user trust of the website and applications. SSL certificates management with timely, effective and safe can also ensure website security.
