A Guide to WordPress File Integrity Monitoring

Do you run a WordPress website? Are you worried about hackers and malware? You should be!

Securing your WordPress site is critical in today’s online world. Hackers are always looking for ways to break into sites. Imagine finding out that someone hacked your site, changed important files, stolen data, or spread malware!

So, how can you protect your site from these threats?

This is where WordPress file integrity monitoring (FIM) comes in. FIM helps keep your website safe by constantly watching over your files. It checks to make sure nothing has changed without your permission.

TL;DR: File integrity monitoring (FIM) helps protect your WordPress site by monitoring file changes and giving early warnings about suspicious activity. Take the first step towards implementing FIM on your site using a malware scanner plugin like MalCare.

Remember the previous example about hackers changing your site files? Without FIM, spotting these changes becomes much harder. FIM gives you a better chance of catching suspicious activity early. This helps you address WordPress security issues before they escalate.

In this guide, we’ll explain what FIM is and how monitoring file integrity impacts security. We’ll also explore different ways to set it up to help you protect your WordPress site.

What is file integrity monitoring?

File integrity monitoring (FIM) is a process that continuously watches over your site files. It monitors your files and alerts you if they have been modified.

Imagine it as a vigilant guard that regularly checks your files and compares them to a safe, original version. If it spots any unwanted or suspicious changes, it raises an alert so you can fix the issue before it becomes a bigger problem.

This is particularly important for WordPress users. Hackers can attack websites and infect them with malware in the blink of an eye. FIM provides early warnings, allowing you to act quickly and prevent potential damage.

Besides enhancing security, FIM is also useful for compliance. Many regulations need websites to maintain a certain level of security. By monitoring file integrity, you can help meet those standards and keep your site in line with legal requirements.

However, when it comes to securing your WordPress site, FIM is just not enough. It has its limitations that we explain later in this article.

Monitor file integrity using a plugin

Using a plugin is the easiest way to set up file integrity monitoring (FIM) on your WordPress site. We highly recommend MalCare for this purpose. It offers an excellent malware scanner that detects even the most obscure malware on your site. It then shows detailed information, including file integrity monitoring (FIM), about your site so that you can remove malware in just one click.

Setting up MalCare is straightforward. Simply sign up and add it to your site. The plugin continuously scans your files for any changes. If it detects unauthorized modifications—which usually indicate malware—it alerts you immediately. This proactive approach helps you address security threats swiftly.

In addition to its FIM capabilities, MalCare offers an activity log. This log provides a detailed record of all actions, suspicious or otherwise, taking place on your site. Unusual activity is often a first indication that something is awry with your site.

MalCare also includes a backup feature, allowing easy restoration of original files if any unauthorized changes occur.

Monitor file integrity using server-level solutions

Server-level solutions can offer more robust and comprehensive file integrity monitoring (FIM). However, they will require diving deeper into your site settings to function. If you don’t feel like doing that, or your web host does not give you access to site settings, we recommend using a plugin like MalCare that makes it easy.

If you still wish to try them out, two of the most popular server-level solutions are Qualys and Tripwire.

Tripwire is a well-known name in the realm of cybersecurity. Their FIM service can catch even the smallest changes to your files. It also offers detailed reports and real-time alerts. But you need to buy their FIM service. This can be a significant investment but may be worth it for the level of security it provides.

Qualys is another strong contender in this space. Unlike Tripwire, they offer a 30-day trial of their FIM solution. So you can test out the service before committing to it financially.

Monitor file integrity using open-source tools

If you’re comfortable with a bit of technical work, open-source tools can provide another effective way to monitor file integrity. One notable option in this space is OSSEC.

OSSEC offers a powerful, open-source tool for FIM. But, there’s a catch—your site must be hosted on a dedicated server. Additionally, it involves some technical configuration to get it up and running smoothly.

This isn’t a plug-and-play solution; you’ll need to have a technical bent to set it up correctly. Use OSSEC only if you enjoy diving into the nitty-gritty details of server management and want complete control over your FIM setup.

But if you’re not technically inclined, you might find the setup process daunting. In that case, you might be better off with a more user-friendly solution like MalCare.

Types of file integrity monitoring

There are two main types of file integrity monitoring (FIM): proactive and reactive. Each has its distinct approach to keeping your site secure.

Proactive FIM

This type of FIM focuses on real-time or nearly real-time detection of file changes. It’s like having a security camera that alerts you the moment it sees suspicious activity.

MalCare’s robust firewall, along with its malware scanner, is a great example of proactive FIM. These tools monitor your files continuously, catching and addressing potential security issues as they happen. This allows you to take immediate action to prevent further damage.

Reactive FIM

On the other hand, reactive FIM identifies and responds to file changes after they have occurred. Think of it as a detective that comes in to investigate a scene post-incident.

Scanning your WordPress site on a schedule or manually falls under this category. These scans periodically check your files for any unauthorized changes, allowing you to respond and fix issues discovered during the scan. While it’s not as immediate as proactive FIM, it still plays a vital role in maintaining your site’s security.

Why do you need file integrity monitoring?

File integrity monitoring (FIM) is one of the many markers used to ensure your website is safe and secure. Here are several reasons why:

Is file integrity monitoring enough?

File integrity monitoring (FIM) is a useful tool for detecting changes that might signal malicious activity. However, it has its limitations.

It’s important to understand that FIM is not a foolproof solution.

One major issue is that hackers can alter the change dates of files. Since these dates are part of what FIM tracks, this can make FIM unreliable in catching all malware.

FIM also merely serves as an indicator; it doesn’t fix issues on its own. It’s like a smoke detector—it tells you there’s a problem, but it doesn’t put out the fire. You need someone who really knows their way around WordPress to effectively interpret what FIM is showing.

Moreover, FIM struggles with customizations. If you’ve made changes to files and compared them to the original repository, you might get false positives. FIM looks for differences and doesn’t always consider legitimate updates or custom modifications.

If you plan to use FIM to spot malware on your WordPress site, keep in mind it’s just one piece of the puzzle. It works best when used alongside a comprehensive malware scanner like MalCare. A good scanner considers multiple signals, not just file integrity, to ensure effective malware detection.

Final thoughts

Keeping your WordPress site secure has become more important than ever. This is where file integrity monitoring (FIM) plays an important role. It helps you spot unauthorized changes to your site’s files quickly. It can also help you stay ahead of hackers, meet regulatory requirements, build user trust, and cut down on downtime caused by security breaches. Whether you choose real-time monitoring or scheduled scans, it’s important to pick a solution that fits your needs and skill level.

However, FIM is simply not enough when it comes to securing your site. It should always be used together with other, more reliable security tools like security plugins, firewalls, etc.

One such reliable tool to secure your site is MalCare. Its robust malware scanner can identify even the most deeply hidden malware. This makes it easy to spot and fix problems right away. MalCare’s smart firewall and vulnerability detection capabilities only add to the overall security of your site. By using a tool like MalCare, you can keep your WordPress site safe, giving you peace of mind in a world full of online threats.
