As you can read in the post installation message that is new as of Joomla 3.9.3, "Since Joomla 3.9.3, Joomla is shipped with additional security hardenings in the default htaccess.txt and web.config.txt files. These hardenings disable the so called MIME-type sniffing feature in webbrowsers. The sniffing leads to specific attack vectors, where scripts in normally harmless file formats (i.e. images) will be executed, leading to Cross-Site-Scripting vulnerabilities.
The security teams recommends to manually apply the necessary changes to existing .htaccess or web.config files, as those files can not be updated automatically." How to manually apply these necessary changes to prevent browsers from sniffing your Joomla site is what today's Maintenance Monday is all about.
Using a CDN (Content Delivery Network) can help improve the page load speed of your Joomla site. A CDN serves files from a server location closest to the physical location of your site visitors and users. Not only does it get those files to your users faster, the increased speed of your site can improve your ranking in search results.
It can also help reduce the load on your server or web hosting account. This episode shows how to set up Joomla to use AWS Cloudfront (Amazon Web Services) as a CDN.
