Require all denied
</FilesMatch>

RewriteRule ^(.*)$ https://%{HTTP_HOST}/$1 [R=301,L]
6. Prevent Clickjacking
Protect your site from being embedded in an iframe:
Code:
Header always append X-Frame-Options DENY
7. Enable Caching and Compression
Improve performance by enabling caching and compression:
Code:
Enable gzip compression
<IfModule mod_deflate.c> AddOutputFilterByType DEFLATE text/html text/plain text/xml text/css AddOutputFilterByType DEFLATE application/javascript application/json </IfModule>
Cache files
<IfModule mod_expires.c> ExpiresActive On ExpiresByType text/css "access plus 1 week" ExpiresByType application/javascript "access plus 1 week" ExpiresByType image/jpeg "access plus 1 month" </IfModule>
8. Block Specific User Agents
Deny access to known malicious bots:
Code:
SetEnvIfNoCase User-Agent "BadBot" bad_bot
Deny from env=bad_bot
9. Prevent MIME-Type Sniffing
Add security headers to protect against MIME-type sniffing:
Code:
Header set X-Content-Type-Options "nosniff"
