WordPress security concerns are extremely valid for a number of reasons. The question often arises “Is WordPress secure?” The answer is that it depends. WordPress itself is very secure as long as WordPress security best practices are followed.
Since WordPress powers 25% off all websites, security vulnerabilities are inevitable because not all users are careful, thorough, or security conscious with their websites. If a hacker can find a way into one of the 700 million WordPress websites on the web, they can scan for other websites that are also running insecure setups of old or insecure versions of WordPress and hack those too.
WordPress runs on open source code and has a team specifically devoted to finding, identifying and fixing WordPress security issues that arise in the core code. As security vulnerabilities are disclosed, fixes are immediately pushed out to patch any new security issues discovered in WordPress. That’s why keeping WordPress updated to the latest version is incredibly important to the overall security of your website.
It’s important to note that WordPress security vulnerabilities extend beyond WordPress core into the themes or plugins you install on your site. According to a recent report by wpscan.org, of the 3,972 known WordPress security vulnerabilities:
- 52% are from WordPress plugins
- 37% are from core WordPress
- 11% are from WordPress themes
Armed with this information, here are 5 common WordPress security concerns.
Brute force attacks.
A brute force attack is a trial and error approach to entering usernames and passwords in an attempt to break into a WordPress installation.The brute force attack method exploits the simplest way to get access to your website: your WordPress login screen.WordPress, by default, doesn’t limit login attempts, so bots can attack your WordPress login page using the brute force method. Even if a brute force attack is unsuccessful, it can still wreak havoc on your server, as login attempts can overload your system. While you’re under a brute force attack, some hosts may suspend your account, especially if you’re on a shared hosting plan, due to system overloads.
File inclusion exploits.
After brute-force attacks, vulnerabilities in your WordPress website’s PHP code are the next most common security issue that can be exploited by attackers. (PHP is the code that runs your WordPress website, along with your plugins and themes.)File inclusion exploits occur when vulnerable code is used to load remote files that allow attackers to gain access to your website. File inclusion exploits are one of the most common ways an attacker can gain access to your WordPress website’s wp-config.php file, one of the most important files in your WordPress installation.
Your WordPress website uses a MySQL database to operate. SQL injections occur when an attacker gains access to your WordPress database and to all of your website data.With an SQL injection, an attacker may be able to create a new admin-level user account which can then be used to login and get full access to your WordPress website. SQL injections can also be used to insert new data into your database, including links to malicious or spam websites.
Malware, short for malicious software, is code that is used to gain unauthorized access to a website to gather sensitive data. A hacked WordPress site usually means malware has been injected into your website’s files, so if you suspect malware on your site, take a look at recently changed files.Although there are thousands of types of malware infections on the web, WordPress is not vulnerable to all of them. The four most common WordPress malware infections are:
- Drive-by downloads
- Pharma hacks
- Malicious redirects
Each of these types of malware can be easily identified and cleaned up either by manually removing the malicious file, installing a fresh version of WordPress or by restoring your WordPress site from a previous, non-infected backup.
Armed with this knowledge of the common WordPress security concerns, you can come up with a plan that will all but avoid these issues. This approach needs to look at the following things to be successful.
Avoid weak passwords.
Using a weak password is one of the biggest security vulnerabilities you can easily avoid. Your WordPress admin password should be strong, include multiple types of characters, symbols or numbers. In addition, your password should be specific to your WordPress site and not used anywhere else.
Keep WordPress, plugins and themes updated.
Allowing WordPress, plugins or themes to become outdated is a major problem for addressing WordPress security concerns. it’s important to always run the latest version of all software installed on your WordPress website. Updates will appear in your WordPress dashboard as soon as they’re available. Make a practice of running a backup and then running all available updates every time you login to your WordPress site. While the task of running updates may seem inconvenient or tiresome, it’s an important WordPress security best practice.
Using plugins and themes from untrustworthy sources.
Poorly-written, insecure, or outdated code is one of the most common ways attackers can exploit your WordPress website. Since plugins and themes are potential sources of security vulnerabilities, as a security best practice, only download and install WordPress plugins and themes from reputable sources, such as from the WordPress.org repository, or from premium companies that have been in business for a while. Also, avoid bootleg or torrented “free” versions of premium themes and plugins, as the files may have been altered to contain malware.
Using poor quality or shared hosting.
Since the server where your WordPress website resides is a target for attackers, using poor-quality or shared hosting can make your site more vulnerable to being compromised. While all hosts take precautions to secure their servers, not all are as vigilant or implement the latest security measures to protect websites on the server-level.Shared hosting can also be a concern because multiple websites are stored on a single server. If one website is hacked, attackers may also gain access to other websites and their data. While using a VPS, or virtual private server, is more expensive, it assures your website is stored on its own server.
By doing the following 8 things, you can ensure that your WordPress security concerns are under control.
Using a Strong Password
If you’re currently using a password that contains fewer than 6 characters, change it now. If you’re currently using a password on more than one login, change it now. If you’ve had the same password for more than six months, change it now. Start practicing good WordPress password security, especially if you’re an admin user. Using a password manager like LastPass makes it much easier to use strong passwords everywhere.
Install a WordPress Security Plugin
Using a WordPress security plugin is a great way to take care of additional security measures on your WordPress website. Most of these plugins offer a one-click WordPress security check that activates the most important and recommended WordPress security settings.
Enable WordPress Two-Factor Authentication
Two-factor authentication adds an extra layer of protection to your WordPress login. In addition to your password, an additional time-sensitive code is required from another device such as your smartphone, in order to login. Two-factor authentication is one of the best ways to lock down your WordPress login and nearly completely minimizes the potential of successful brute force attacks.
Keep Your WordPress Site Updated
Again: keeping your WordPress site updated is one of the best ways you can avoid potential WordPress security issues. Login to your WordPress site now and run any available updates for WordPress core, your themes or plugins. If you’re using premium WordPress plugins or themes, make sure you have a current license to ensure you’re getting updates and not running outdated versions.
Setup Proper Permissions on Your Server
Ensure proper permissions are set on all directories on your server. Proper permissions dictate who has permission to read files, create and edit files.
Run Scheduled Malware Scans
Keep tabs on potential malware infections with scheduled malware scans. Most services give you a report on your website’s malware status along with several other blacklisting statuses.
Have a Reliable WordPress Backup Plan
Having a WordPress backup plan is an important component of your WordPress security strategy. Set up scheduled backups to run and make sure you’re sending your backups safely off-site in a secure, remote WordPress backup location. Also, make sure your backup strategy has a restore component in case you need to restore a backup.
Activate WordPress Brute Force Protection
Protecting yourself from brute force attacks is another way to reduce any potential vulnerabilities or server overloads. Use a service that includes both local and network brute force protection to ban users who have tried to break into other sites from also breaking into yours.
While WordPress security issues do exist, most can be avoided with WordPress security best practices and an awareness of the potential security risks. Armed with knowledge and strategies to protect your WordPress site, you can greatly minimize your vulnerability to hacks and keep your WordPress site safe and secure.
