WordPress: risks and security


Internet is unsafe, by definition. Cryptanalysis  and  cryptography shave always gone hand in hand: for every system vulnerability  there is a possible unpleasant spammer, hacker, or cracker intrusion. They can study and take posession of such a system in order to to use it according to their needs. This penetration can lead to incommensurable damage, compromising our data and violating our privacy.

Today, we are going to deepen the topic of the security of one of the most used CMS (Content Management System) in the world: WordPress.

Risks and security of WordPress

As already asserted , WordPress is an important content management system, which is regularly updated and developed. It allows the use of templates (collections of files aimed to modify the graphical interface of a a website and not the core functionality) and plugins (external components that can be integrated to WordPress to extend its functionalities) in order to make possible any customization of a website.

Come in ogni cosa, c’è l’altra parte della medaglia. Difatti, tutte queste parti del sito devono essere debitamente aggiornate, altrimenti possono crearsi delle vulnerabilità fatali per la sicurezza del sito WordPress.

As in all things, there is the other side of the coin. In fact, all of these parts of the website must be kept up to date, otherwise vulnerabilities may be generated, which are fatal to the security of WordPress.

WordPress Security

CMS must be updated as soon as possible. In most cases, the latest versions contain security improvements or corrections while the oldest ones may present vulnerabilities.

To protect WordPress template integrity is important to follow some tips by the developers of the CMS:

  • Limit access: minimize the risk of creating vulnerabilities
  • Containment: reduce to the maximum the amount of damages that a possible intrusione could cause, in the case website security is jeopardized
  • Regalar monitoring: backup everything periodically and monitor the website continuously
  • Reliability: it is highly recommended not to download or purchase templates from untrusted sources

WordPress plugin security

WordPress Plugins security

As specified for the other parts, also WordPress plugins have to be regularly kept to date. Moreover, it is recommended to be used only the strictly necessary plugins for your website. Others shouldn’t be just deactivated, but deleted completely.

Not necessary plugin must be DELETED, not only deactivated!

It is important to install plugins that act as a firewall for the website. There are many plugins with this functionality, some of which really useful.


wordpress utente passwordThe choice of password is really relevant. We are asked to enter our password to access WordPress back office, files through FTP protocol or various control panels of the website.

First of all, it is better that the password are different between them, even though any possible intrusion allows the intruder to execute almost every operations he has in mind.

When you choose a password you have to keep in mind the following conditions in order to prevent Brute Force Search attacks:

  • Name, username, company, website etc.
    • e.g. Nome: Frank, Password: frank123
    • e.g. Username: francis, Password: 4francissss
  • Dictionary words, of any language
    • e.g. homeasa123
  • Short passwords
    • e.g. tris
  • Passwords containing only numbers and letters
    • e.g. 123456 or homepage

In order to have a secure password, it is fundamental using a permutations of numbers, letters (lowercase and uppercase) and special characters, with minimum length of 8 digits:

Secure passwords examples:

  • rfR@3sP”!Fv
  • G)c#*Nb3vT4
  • p_09Xw!“cvj27F5GH=!

WordPress username

It is very important to avoid usernames like: admin, webmaster, Name or website because they are the most attacked. Using a difficult username (combined with a very strong password) would get the hacker’s job very hard and, at least, this point of entry would be safe.

Moreover, it is recommended to rename the table prefixes of the database. The default prefix is “wp_” and it is taken for granted by hackers. Therefore, by modifying it to something different (it is ok also “abc_”, but it is better “z6d3p92md93u_”) would avoid the SQL injections hacking.


These are just some parts of the WordPress security; there are also many more.The topic of security is very wide and in cintnuous evolution. Therefore, it is really important to get informed regular about new malware and about methods to stop them.
