How to Run a WordPress Security Audit
A WordPress site can do a lot. However, it also needs looking after. Security isn't always the first thing on your list, but ignoring it can cost you more than just traffic. A weak spot in your setup can put customer data at risk, damage your reputation, or take your site offline altogether.
The truth is, most threats don't come from some elite hacker group. They come from everyday things. These may include an outdated plugin, a weak password, or a setting that was never reviewed. That's why running a WordPress security audit isn't just a "nice to have." It's something every site owner should do regularly.
What is a WordPress security audit?
A WordPress security audit involves reviewing your website to detect vulnerabilities, signs of tampering, or any activity that doesn't belong. It's a proactive approach to identifying issues like hidden malware, outdated plugins, or sudden performance drops before they develop into bigger problems.
During an audit, the goal is to identify anything that might compromise your site's integrity. That includes scanning for unauthorised logins, unexpected file changes, or code injections hiding in plain sight. Some checks can be done manually with a bit of technical know-how, while others require specialised tools that comb through your files and configurations with precision.
The key benefits of running regular security audits
Regularly auditing the security of your WordPress site brings several tangible benefits.
1. Spotting weaknesses before hackers do
Every piece of software, whether it's plugins, themes, or the WordPress core itself, can have flaws. Developers release patches when they discover vulnerabilities, but those patches don't always arrive immediately. In the meantime, hackers can exploit these weaknesses. Security audits help you identify these issues early, whether it's outdated software, a misconfigured setting, or something as simple as weak passwords. Identifying and fixing these problems means you're staying one step ahead of potential threats.
2. Securing sensitive data
WordPress sites often store sensitive user information like passwords or payment details. If that data is compromised, you may face both financial and reputational damage. A breach can result in stolen data or, worse, lost data. A security audit looks at your site's overall security to ensure that user information is protected. This is very important, especially when dealing with customer trust. Ensuring data is encrypted and stored securely goes a long way in making sure your visitors feel safe.
3. Preventing downtime
A website that goes down due to a security breach isn't just an inconvenience. It's a risk to your business. Downtime means lost opportunities, be it potential sales or customer engagement. Hackers often target sites to bring them offline or disable them. Regular security audits ensure there's no vulnerability for hackers to exploit, which means your site stays accessible without interruptions.
4. Building and maintaining trust
Trust is everything in the online world. A security breach can damage your brand's reputation and drive customers away. Users who don't feel their data is safe are less likely to engage with your website. Running a WordPress security audit regularly shows visitors that you take their security seriously. It's a strong signal that you're looking out for their privacy, which keeps them returning.
5. Improving performance
Security issues affect safety and can slow your website down. Things like outdated plugins or improperly configured settings can impact site speed. When you take the time to audit your security, you're also improving your site's efficiency. Performance matters, and running a smooth and secure website improves user experience and even helps with SEO rankings.
6. Avoiding legal trouble
As data protection laws tighten worldwide, failing to keep your site secure can result in hefty fines or legal action. Regulations like GDPR or CCPA require businesses to protect personal data, and if your website fails, the consequences can be costly. Running regular security audits keeps you in line with these regulations and reduces the chances of facing legal trouble.
7. Saving time and money
Dealing with a breach is expensive. Beyond the initial cleanup costs, there are forensic investigations, legal fees, potential lawsuits, and the PR effort to repair your brand's reputation. Catching issues before they escalate is much cheaper and more efficient than responding to an attack. Regularly auditing your WordPress site will save you from these future costs and ensure your site stays protected and running smoothly.
When to run a WordPress security audit
Knowing when to run a WordPress security audit is important for maintaining your site's security. Consider performing an audit during these key moments.
1. After major updates
Whenever you update the WordPress core, themes, or plugins, perform a security audit. Updates can introduce new vulnerabilities, so reviewing the changes ensures that no issues have been overlooked.
2. When you notice unusual activity
If your website experiences unusual behaviour, conduct a security audit. Unusual behaviour includes unexpected login attempts, traffic spikes, or other irregularities. These anomalies can be indicators of a security issue that needs attention.
3. After a hack or attack
Run a thorough security audit in the unfortunate event of a hack or attack. This helps you identify how the breach happened, what damage was done, and what steps need to be taken to prevent future attacks.
4. If you switch web hosts
Changing web hosts can impact your site's security settings. A security audit ensures that everything is correctly configured on the new server and that your site remains secure after the transition.
5. Before major events or launches
Running a security audit before significant events like a product launch or a high traffic event is a smart move. It helps ensure your site can handle increased activity without compromising security.
6. Before adding new features
New features and functionalities can introduce vulnerabilities. Before adding anything new, conducting a security audit helps ensure these additions do not risk your site's overall security.
How to perform a manual WordPress security audit
Running a manual WordPress security audit doesn't require expensive tools or developer level expertise. What it does need is a structured checklist and a bit of patience.
1. Start with the basics
Begin your audit by checking that everything is current. Outdated WordPress components are often the weakest link in site security.
- Log in to your WordPress admin panel.
- Navigate to Dashboard → Updates.
- Review if the core WordPress software, any active plugins, or themes have pending updates.
- Install all available updates one by one. Start with the core, then plugins, and finally themes.
Don't stop there. Head over to Plugins → Installed Plugins and Appearance → Themes to deactivate and delete anything you're no longer using. Leaving inactive plugins and themes sitting around is like locking your front door but leaving the windows wide open.
2. Check user accounts
Once your software is up to date, it's time to look at who's inside your site.
- Go to Users → All Users from your dashboard.
- Review the list of accounts. Ask yourself whether you recognise this person, and whether they should still have access.
- You typically won't need more than one or two admins for blogs, portfolios, or business sites. Large lists with strange usernames or unfamiliar email addresses should raise a flag.
To tighten things up further:
- Visit Settings → General and find the Membership section.
- Ensure the "Anyone can register" box is unchecked unless you intentionally allow public registrations, as you would on a membership or WooCommerce site.
Even if everything looks fine, change your administrator password as a precaution. Pick a long, complex password, ideally a mix of uppercase, lowercase, numbers, and symbols. And if you haven't already, install a two factor authentication plugin. It adds an extra wall between your site and anyone trying to force their way in.
3. Run a front end security scan
Now that you've cleaned up internally, turn your attention to what's publicly visible.
- Use a scanner like IsItWP Security Scanner.
- Enter your site URL and let it run a scan.
These WordPress security audit tools will check for malware signatures, outdated software, and any blacklisting issues. While they can't look into your database or admin panel, they're great for spotting surface level infections or redirecting malware. This step won't fix anything, but it will show you what might be wrong, especially if your site has been compromised and you're unaware of it.
4. Dig into your website traffic patterns
Traffic stats can tell you a lot if you know what to look for.
- Open your analytics dashboard. If you're using MonsterInsights, access it directly inside WordPress.
- Look at metrics like total pageviews, bounce rate, and referral sources over the past 30 days.
Sudden drops in traffic could mean search engines have flagged or blacklisted your site. An unusual spike in traffic from suspicious countries or URLs might hint at a bot attack or spam activity. Also keep an eye on pages that are receiving traffic unexpectedly, unusual user behaviours or login attempts, and referral traffic from shady domains. Your analytics tool might not scream that you've been hacked, but it will whisper if something's off.
5. Confirm that backups are active and reliable
A manual audit should always include verifying your backups, because prevention is great, but recovery saves you when all else fails.
- Check which plugin you're using for backups, such as UpdraftPlus or BlogVault.
- Go to that plugin's settings page and look for the most recent backup date.
- Download a copy of your latest backup to local storage or a cloud drive. Then test whether you can access and restore it, even partially.
Don't just assume backups are happening on schedule. Many plugins rely on cron jobs or external services, and a misconfiguration could stop them silently. Also check where your backups are stored. Keeping a local backup on the same server as your site won't help much in a server crash or cyberattack.
How to perform an automatic WordPress security audit
Manually checking security basics is a good start. However, it's rarely enough. Keeping an eye on file changes, tracking user actions, or catching malicious code slips through the cracks when done manually. That's where automation saves time and catches what you might miss.
1. Set up a WP Activity Log to monitor user behaviour
If multiple users have access to your WordPress backend, keeping tabs on their actions is non negotiable. WP Activity Log gives you visibility into everything happening behind the scenes, including logins, changes to posts, and plugin activity.
- Go to your WordPress dashboard and navigate to Plugins → Add New.
- Search for WP Activity Log and click Install Now, then Activate.
- Go to WP Activity Log → Enable/Disable Events once activated. From here, choose exactly what you want to monitor, such as post changes, user profile edits, and file uploads.
- Check the Logged In Users section to see active sessions. If you notice any unusual activity, for example an admin logged in from an unexpected IP, you can end the session directly.
- Head to the Audit Log Viewer to browse the real time activity log. The WordPress security audit log helps in quickly identifying anything that looks off.
2. Use Sucuri for deep scans and traffic filtering
WP Activity Log covers user side monitoring. But what about malicious code, file injections, or bot traffic? That's where Sucuri is used. It is considered an all in one plugin acting as the site's bodyguard, firewall, and cleaner.
- From your WordPress admin, go to Plugins → Add New, search for Sucuri Security, install it, and activate it.
- After activation, go to the Sucuri Security dashboard. You'll be prompted to generate an API key to connect to their security network.
- Once that's done, the plugin will immediately start scanning your site for known threats, like modified core files or malware patterns.
- Turn on Post-Hack actions such as email alerts and file integrity checks. This keeps you updated if any core file gets altered without your knowledge.
- To fully use the firewall and DDoS protection, you'll need a paid Sucuri plan. Once subscribed, you'll receive DNS instructions to route your traffic through Sucuri's firewall.
3. Scan for vulnerabilities with Wordfence
Wordfence offers both a firewall and a malware scanner, but what makes it really useful is its ability to flag known vulnerabilities in plugins, themes, and even WordPress core files.
- Go to Plugins → Add New and search for Wordfence Security. Install and activate the plugin.
- On activation, go to Wordfence → Dashboard, and complete the setup wizard.
- Go to Scan → Start New Scan once the plugin is ready. This checks for file changes, known malware, plugin vulnerabilities, and blacklisted IPs.
- Review the scan results. Wordfence usually provides a link to update or fix the issue if you see plugin vulnerabilities.
- Set up scheduled scans under Scan Options, so you don't have to remember to run them manually every time.
Enable email alerts for critical issues so you're not caught off guard.
4. Track file changes with iThemes Security
Where WP Activity Log focuses on users, iThemes Security focuses on your files and system integrity. It's great for detecting suspicious behaviour like core file tampering or unauthorised changes to configuration files.
- Install iThemes Security from the plugin directory and activate it.
- Navigate to Security → Settings and turn on File Change Detection.
- Configure how often the plugin should scan your file system. Daily scans usually work well unless your site sees frequent updates.
- Head to the Notifications section and set up alerts, so any unexpected file change triggers an email notification.
This method works well alongside WP Activity Log and Wordfence, especially when you want to catch changes that don't leave a user trail.
5. Monitor uptime and SSL with Jetpack Security
Security isn't just about what's happening inside WordPress. Things like expired SSL certificates or frequent downtime can open up vulnerabilities too. Jetpack's security module offers uptime monitoring, brute force login protection, and alerts for plugin updates.
- Install Jetpack from the plugin library and connect it with a WordPress.com account.
- Activate the Security module, which includes downtime monitoring and backup options.
- Go to Jetpack → Settings → Security and make sure features like Brute Force Protection and Downtime Monitoring are turned on.
- Enable notifications so Jetpack emails you if your site goes offline, your SSL certificate expires, or an outdated plugin becomes a risk.
This helps you stay ahead of availability and encryption related issues, which often go unnoticed until users complain.
