Configuring HSTS (HTTP Strict Transport Security)

HSTS is a policy that tells browsers to only interact with your site using HTTPS. This helps prevent attacks. To enable HSTS, add a special header to your server's responses. Here's an example for Apache servers:

Header always set Strict-Transport-Security "max-age=31536000; includeSubDomains" 

Managing Mixed Content Warnings

Mixed content happens when a secure page (HTTPS) loads resources (like images or scripts) over an insecure connection (HTTP). This can make your site less secure. To fix this, update all resource URLs to HTTPS. You can use browser tools to find and fix these issues.

Remember, SSL/TLS configurations can be manually reviewed, including the supported protocols, cipher suites, and certificate details, to identify potential weaknesses.

What is an SSL certificate?
