The WordPress content management system (CMS) powers approximately 40% of websites on the internet, making it the largest CMS by market share. While this popularity ensures that the platform enjoys robust support from both internal and external developers, it also makes WordPress websites an attractive target for scammers and hackers.
If this leaves you concerned about security risks from using WordPress, keep in mind that the CMS itself is secure — it simply requires customization and good management to minimize vulnerabilities due to the open-source nature of the platform.
Importance of WordPress Security Best Practices
Using WordPress security best practices helps prevent unauthorized access or hacked websites. This open-source CMS provides users and developers alike with transparency in terms of the underlying code, but the downside is that it also lets bad actors exploit WordPress vulnerabilities. For instance, default WordPress setups put the administrative login on a fixed page, leaving it visible to hackers. For this reason, WordPress developers suggest changing the name of the login page to something less visible to those who wish to steal your information.
Common WordPress Security Vulnerabilities and Risks
WordPress security issues encompass roughly five key categories, each with their own particular way of letting hackers gain access to WordPress sites. Fortunately, each of these issues that makes your WordPress site vulnerable have easy fixes.
1. Outdated WordPress Core, Plugins or Themes
Some of the common WordPress vulnerabilities are outdated core, plugins or themes. When issues arise, the WordPress security team and developers of plugins and themes typically release updates to address them, but that very release can reveal the WordPress security vulnerabilities to the public, including hackers and scammers. This means that the faster you update outdated core installations, plugins and themes, the better chance you have at keeping WordPress secure. The key to maintaining this sort of security threat is keeping your WordPress installation, themes and plugins updated and ensuring any background software is updated as well.
2. Brute Force and DDoS Attacks
Another common WordPress security issue is brute force attacks. As mentioned above, leaving the WordPress login page on the default URL upon installation enables hackers to use a brute force attack to gain access to your website. This typically occurs when they use trial-and-error methodology to enter various username and password combinations until they log in successfully.
Even when these attacks are unsuccessful, they can overload your server and slow your WordPress website to a crawl. Secure passwords that utilize uppercase and lowercase letters plus numbers and symbols help foil these attacks as does hiding your WordPress login page. To further reduce security threats, limit login attempts and enable two-factor authentication.
Distributed denial of service (DDoS) attacks happen when hackers send a multitude of requests to a web server, causing it to slow and then crash. Utilizing multiple infected machines from around the world, these organized attacks have the potential to cost your business big money. Fortunately, a good web host like WPSitePlan mitigates these sorts of attacks by managing web server security and coming to the rescue when suspicious activity occurs.
3. File Inclusion and MySQL Database Exploits
Software exploits that attack vulnerabilities in PHP software used to run your WordPress site or your MySQL database can also help hackers gain access to your WordPress website. When hackers attack these background elements, they typically do so through a file inclusion export or SQL injection. Both techniques let hackers load remote files into your website files via outdated versions, providing access to your WordPress configuration file and the ability to change anything they like.
An easy way to prevent file inclusion exploits or fix SQL injection issues is to use a managed host like WPSitePlan that’s experienced in dealing with common WordPress security issues. A well-managed WordPress host keeps these essential background files updated to keep hackers out.
4. Poor Security and Credentialing
Another way hackers can gain unauthorized access is through poor security and credentialing. When you set up your website, your WordPress dashboard provides options to create five user roles, each with its own level of access — administrator, editor, author, contributor and subscriber. Administrator accounts are the most powerful, providing unlimited access to your entire website and allowing hackers to change everything from site files to the bank account where your e-commerce sales go. The key way to prevent unauthorized access is to be careful with login credentials, ensuring administrative user credentials are properly assigned only to those you trust with your WordPress website.
5. Cross-Site Scripting
They then use this hack to steal login credentials to access a user account. To avoid cross-site scripting, be sure to validate website data properly and use output sanitization — or simplify the process with a WordPress security plugin recommended by your web host.
Eliminating WordPress Security Vulnerabilities and Risks
A well-managed web host such as WPSitePlan understands WordPress security vulnerabilities and risks and works hard to keep your site up and running. Also equipped to handle other threats to your site’s security like malware and phishing attempts, a well-managed web host performs daily security scans, keeps your WordPress themes, plugins and core up to date and provides daily backups so you can revert back to a good version should your site’s database get hacked.
Keeping your WordPress website free of common security vulnerabilities and risks lets you enjoy maximum uptime, which is good for your business.
