Choosing WordPress to power your site means WordPress is the basis of everything on your site. The fact that it is free and open source has many advantages. But with each update, the exploits of the previous version are made available to the public, making previous versions more likely to be hacked. By using back safety through dark tactics, you can remove or hide the version number of your WordPress installation. You can even choose a simpler solution with plugins to hide the version number. This may deter a bot from connecting to your site, but that does not correct holes in older versions of WordPress. Only updating your WordPress installation as new versions become available will remove published exploits.

The update of WordPress is simple (since version 3.7 is released with automatic updates)
In previous versions of WordPress, a new banner appears in your dashboard whenever an update is available. From now on, WordPress installations will automatically be updated to new minor versions without you having to lift a finger. Minor versions are usually for security updates. However, you will still need to update for new major releases.

To update WordPress

  1. First of all! Save your WordPress.
  2. Dashboard
  3. Updates

The biggest threat to your site
The fastest way to compromise your site is to add poorly coded, outdated, or obsolete themes or plug-ins to developers or unreliable sites. Due to the open source nature of WordPress, many themes or plugins are distributed under GPL or GPN (General Public License) licenses. So it's easy to create and redistribute themes and plugins to free WordPress theme and plug-in sites by adding hidden or malicious code. This code can be as simple as exposing a virus or as serious as exposing your visitors to identity theft.

Before downloading a theme or a free plugin:

  1. Search for the author and download it only from the website of the author or the WordPress custodian
  2. Ask WordPress.org/support for advice
  3. If you are going to use for free of confidence plugins or themes, check the compatibility list of version numbers and check that the plugin or theme is still supported and updated. Many themes or plugins are slow to receive updates or are simply abandoned.
  4. If you do not use it, lose it. If you do not use a theme or plug-in, delete it.
  5. Use supported themes and plugins (not free).

Experience shows that almost all WordPress attacks could be defended and defended simply by using safe, up-to-date and reliable plugins and themes.
