How to secure WordPress without a security plugin?

Hello,

I will try to focus purely on the Wordpress side of things, but of course, having a secure server is also extremely important.

Here are some of the things that I could suggest:

The basics:

• Always update WordPress to the latest version Security is arguably the most important reason why you should keep your WordPress website up to date. You really do not have any excuses for not updating your WordPress version as this can be done with just a click of a button and it only takes a few seconds/minutes.

• Keep an eye on your plugins I would strongly recommend to keep the plugin count to a minimum and always keep your plugins updated. More often than not attackers are able to gain access via an outdated plugin. I would also suggest deleting any plugins that you are not using

• Delete any themes that you’re not using Quite often people would install a few themes and just leave them on the site disabled and outdated. This opens up a lot of vulnerabilities so I would suggest just deleting any themes that you do not use and just have your active theme installed.

The power of the .htaccess file - Here are some nice .htaccess rules that you could use in order to protect your site, this takes only a few minutes to copy and paste these rules into your .htaccess file so I strongly suggest that you add at least some of them.

• Protect your wp-config.php:

<files wp-config.php>
  order allow,deny
  deny from all
</files>

• Secure your wp-includes folder:

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^wp-admin/includes/ - [F,L]
RewriteRule !^wp-includes/ - [S=3]
RewriteRule ^wp-includes/[^/]+\.php$ - [F,L]
RewriteRule ^wp-includes/js/tinymce/langs/.+\.php - [F,L]
RewriteRule ^wp-includes/theme-compat/ - [F,L]
</IfModule>

• Protect the .htaccess

<files ~ "^.*\.([Hh][Tt][Aa])">
  order allow,deny
  deny from all
  satisfy all
</files>

• Disable hotlinking Note: Change the yourdomain.com part.

RewriteEngine on
RewriteCond %{HTTP_REFERER} !^$
RewriteCond %{HTTP_REFERER} !^http(s)?://(www.\.)?yourdomain.com [NC]
RewriteRule \.(jpg|jpeg|png|gif)$ - [NC,F,L]

• Disable directory listing

Options -Indexes

• Disable all php files in your uploads folder. This one is a bit more specific as you should not add it to your main .htaccess file. Upload a file called .htaccess to the root of wp-content/uploads with the following line:

<Files *.php>
  deny from all
</Files>

Protect your wp-admin area

• Use 2FA - For example, you could try using the Google authentication plugin.

• Enable limit login attempts - This would protect you against brute force attacks.

• Enable reCacptcha - Generally speaking, this would protect you against any kind of bots.

• Last but not least - Use a complex unique password for your admin user.

I hope that this helps and if anyone has any other suggestions please feel free to add them below!
