    What Is A WordPress Security Audit?

    In a nutshell, a WordPress security audit is an examination of your website’s security measures. But conducting a WordPress security audit, you be able to identify the additional security measures to employ to make sure your site is fully secured and protected.

    Running a complete security audit involves quite a few steps and will become overwhelming if you don’t follow a specific process and have your checklist ready to go.

    Even if you’ve run a security check in the past, this guide is to assist you in setting up a process that you’ll be able to repeat every three months. In a perfect world, you’d run a security audit every single day. But if you don’t have that kind of time, once every three months is a great place to begin.

    Why Run a WordPress Security Audit?

    With so many threats to your website, it’s important to make your WordPress site as secure as possible. Running a WordPress security audit of your website helps you prepare for and prevent successful attacks on your site. You can’t protect your site from every possible issue, but you can make sure you’re prepared for the most common threats by running a WordPress security audit.

    At some point in time, nearly every website running on WordPress is going to face security issues. For example, themes and plugins can have vulnerabilities that hackers can exploit and gain access to your site with malicious intent.

    Once they’re in, they’ll be able to display unauthorized ads and content, divert your site traffic to another website, rip off your customers or even steal personal data. These scenarios are just the beginning of what a hacker can do when they access the backend of your site.

    Running a full WordPress security audit will assist you in identifying these types of issues right away so that you can shut down any gaps of security on your website.

    How to Perform a WordPress Security Audit: 14 Questions to Answer

    To keep things as simple as possible, here are the numbered steps you’ll want to take every time you run a full security audit of your website.

    1. Is all software on your website up to date?

    When going through your WordPress security audit, one easy but very important thing to check is whether or not everything is up to date on your website. This includes all plugins, themes and WordPress itself. Do you have any pending updates on your site for your plugins, themes, or WordPress itself?

    With WordPress especially, version updates often include security fixes and improvements.  If you’re running older versions, any security issues are typically known and can be exploited. That’s why it’s so important to keep everything on your WordPress site updated.

    Updates are located in your WordPress admin dashboard in a few different places. (This is likely intentional, due to how important updates are to the health and security of your site.)

    wordpress updates

    You can automate updates on your site using the iThemes Security Pro WordPress version management feature. Automating your updates ensures you get the critical security patches that protect your site against WordPress security vulnerabilities and as a bonus, it reduces the amount of time you spend maintaining your WordPress site.

    Tip: Use a service like iThemes Sync to quickly run updates if you manage multiple WordPress websites.

    2. Who has admin level access to your site?

    WordPress lets multiple users contribute and collaborate in site maintenance and development. But not every one of your users will require full administrative access to your website. Know the right user role for each of your users – not everyone will need full access. Limiting access limits security issues from users.

    A prime example is a writer. They’ll only need access that allows for writing and publishing content. They don’t, however, require access that allows them to make other site changes like updating themes or installing plugins.

    To help you properly categorize your site users, WordPress offers six distinct user roles that you can assign to each of your users.

    • Super Admin
    • Administrator
    • Editor
    • Author
    • Contributor 
    • Subscriber

    Note that each one of these roles has its own unique site permissions.

    When you conduct a WordPress security audit, you’ll first want to analyze each of the users you’ve added to the backend of your site.

    • How many users have full admin access?
    • How many users actually need admin access?
    • Can you restrict site access by giving lower permissions for the ones who don’t require admin access?
    • Do you recognize every user that has access to the dashboard? If not, delete the users that you don’t recognize because they could be rogue accounts that hackers have created on your site.

    After you’re done, make sure that any individual who’s a site admin isn’t using the name, Admin. This is far and away the most common WordPress username, which hackers take advantage of to try to gain unauthorized site access.

    If someone has an Admin account, you’ll first need to create a brand new account for the person and assign the existing content to the new user account.

    After that’s done, simply delete the account called Admin.

    3. Are you using two-factor authentication?

    Adding WordPress two-factor authentication is one of the best methods to secure login access to your site. Two-factor authentication requires users to use an authentication token in addition to their username and password to login to WordPress.

    Even if a correct username and password are phished directly from a user’s email, the malicious login attempt can still be prevented if the user is using the mobile application to receive their authentication token. Two-factor authentication adds an incredibly strong layer of security to your WordPress site, and can easily be added using a plugin like iThemes Security.

    In fact, recent research from Google confirms using two-factor authentication can stop 100% of automated bot attacks. I like those odds. iThemes Security Pro makes it easy to add two-factor authentication to WordPress websites.

    4. Do you have a backup solution for your WordPress site?

    If anything goes wrong during a security audit, you’ll be happy that you have a full backup of your site that you can immediately put to use. This allows you to quickly restore your site and get it back to normal if something goes wrong.

    But have you considered what you’d do if even your backup copy failed? What would you do if you couldn’t restore your site at all?

    This is why it’s important to not only have a backup solution but to test it. If all you’re using for site backup is a tool from your host, many don’t allow you to run a test.

    Instead, download and install the WordPress backup plugin called BackupBuddy. This plugin automatically takes complete backups of your entire website.

    Keep in mind that the very first backup you take of your site could take a bit of time, as it copies your entire site onto a backup server. However, future backups will be a lot faster as they will only back up the changes you’ve made to your site since the prior backup.

    Once you’ve used BackupBuddy to complete your site backup, you’ll be able to go into the dashboard and test how it will be restored.

    5. Do you have any unused WordPress plugins?

    Vulnerable plugins are the weak point for so many different WordPress hacks. Plugins are tools created by developers that also maintain them and keep them updated. But, as with all forms of software, different security vulnerabilities can become an issue over time.

    Most plugin developers fix these issues quickly and release an update for users to download and install. Updates are often specific security patches that remove a vulnerability from your website.

    It’s important to download these updates right when they become available.

    During your WordPress security audit, take a look at the list of installed plugins on your site. Most WordPress site owners like to try out new plugins to see what they’ll do. But we’ll often not use them permanently and forget that we’ve installed them.

    Take some time to delete the plugins you’re not using. This takes away all unneeded elements on your site and reduces the risk of a hacker breaking in.

    Make sure that all of the plugins you’re running are familiar and that you recognize them. If you don’t recognize a plugin that’s running and you’re sure your team didn’t install it, it’s best to get rid of it post-haste. It could potentially contain malware that is infecting your site.

    Hackers will often use pirated software to distribute malicious malware.

    6. Do you have any unused WordPress themes?

    As a WordPress site owner, it’s common to install many different themes to find the one that we want to stick with. However, if you forget to delete the ones you’re not using, you’ve opened your site up to dangerous vulnerabilities.

    WARNING: Remember to delete themes and plugins you aren’t using. Unused themes and plugins leave your site vulnerable to dangerous attacks.

    Because of this, it’s important to delete all of the themes that aren’t in use and only keep the theme that’s currently running.

    Also make sure that your theme is updated to the latest version.

    7. Do you have any inactive users on your site?

    Much like outdated plugins and themes on your site, inactive users can be exploited to attack your site.

    Did you have a support person working on your site who you created a user for? Go ahead and delete that user.  If they’re not active on your site, they don’t need a user account.

    8. What does your web host do to secure your website?

    Due to shared hosting technology, more people than ever can now create their own websites with a very minimal investment. These shared hosting plans are very inexpensive and are tailored mostly for small websites.

    When you first launched your WordPress site, you probably went with one of these shared hosting plans. But as your site has grown, so have your hosting needs.

    TIP: Evaluate your hosting needs on a seasonal basis or whenever you make a major change in your business.

    Shared hosting means that you’re sharing a server with a lot of other sites. You don’t have any control over what these other sites that share your server are doing. If one of their sites gets hacked, it will probably consume a lot of server resources.

    This issue will slow your site down and bring its performance down to a halt.

    There’s also a chance that a malware infection can spread to your site from a different site running on your shared server. In other words, if you can afford to upgrade past shared hosting, it’s probably time to get on a dedicated server.

    Remember that quality hosting doesn’t normally come in at $4 per month. Take a look at the dedicated hosting plans that iThemes offers if you’re looking to power up your site and make sure it’s fully secure.

    9. Are you limiting login attempts?

    By default, there isn’t anything built into WordPress to limit the number of failed login attempts someone can make. Without a limit on the number of failed login attempts an attacker can make, they can keep trying a combination of different usernames and passwords until they find one that works.

    By limiting login attempts, you greatly reduce the opportunity for brute force attacks. Brute force attacks refer to the trial and error method used to discover usernames and passwords in order to hack into a website. WordPress doesn’t track any user login activity, so there isn’t anything built into WordPress to protect you from a brute force attack.

    The good news is that you can limit login attempts with the iTheme Security plugin. The iThemes Security Pro Local Brute Force Protection feature keeps tracks of invalid login attempts made by a host or IP address and a username. Once an IP or username has made too many consecutive invalid login attempts, they will get locked out and will be prevented from making any more attempts for a set period of time.

    10. Is your website HTTPS?

    An easy way to tell if the website you are visiting has an SSL certificate installed is to look in your browser’s address bar to see if the URL starts with HTTP or HTTPS. If the URL begins with an HTTPS, you are safely browsing on a site using SSL.

    The security benefits you gain from having an SSL certificate on your website is enough to make it a must-have for any website. However, to encourage everyone to protect their site visitors, web browsers and search engines have created negative incentives to encourage everyone to use SSL.

    Here’s more information on what is SSL and how to install it on your site.

    11. What users have FTP/sFTP access to your site?

    FTP, or File Transfer Protocol, is a technology that allows you to connect your local workstation to your website’s server. With it, you can access all of the folders and files of your site and make necessary changes.

    Because FTP access gives users the ability to delete and modify site files, you should only grant FTP access to people you trust and require this kind of site access.

    It’s best to check your list of users, then reset the FTP passwords if you need to.

    To change passwords, go into your WordPress hosting account and navigate to cPanel > FTP accounts.

    Remember to delete any user that doesn’t need FTP access to your site files.

    12. Are you monitoring security activity?

    Monitoring security activity on your WordPress site is a good way of tracking suspicious activity on your site. That’s where WordPress security logs come in. WordPress security logs provide detailed data and insights about activity on your WordPress website. If you know what to look for in your logs, you can quickly identify and stop malicious behavior on your site.

    WordPress security logs have several benefits in your overall security strategy. If your site does get hacked, you will want to have the best information to aide in a quick investigation and recovery.

    • 1. Identity and stop malicious behavior.
    • 2. Spot activity that can alert you of a breach.
    • 3. Assess how much damage was done.
    • 4. Aide in the repair of a hacked site.

    Here are a few activities you need to monitor with WordPress security logs:

    1. WordPress Brute Force Attacks – It is up to you to monitor your login security to protect your WordPress site. Luckily, a brute force attack isn’t very sophisticated, and it is pretty easy to identify in your logs. You will need to record the username and IP that is attempting to login and whether or not the login was successful. If you see that a single username or IP has consecutive multiple failed login attempts, the chances are you are under a brute force attacks.
    2. File Changes – Even if you follow the WordPress security best practices, there is still a chance for your site to become compromised. A compromise means the site has had malicious changes, and that is why is it is so important to stay on top of the file changes on your site by recording them in your WordPress security logs. File change entries include files added and removed and modifications to existing files. Now that you have the changes recorded in your security logs, you should schedule the time to audit them. If you are an iThemes Security Pro user, remember to enable File Change notifications to be notified when a file changes.
    3. Malware Scans – Not only should you run WordPress malware scans, you should also be recording the results of every malware scan in your WordPress security logs. Some security logs will only record scan results that fund malware, but that isn’t enough. It is crucial to be alerted as quickly as possible of a breach to your site. The longer it takes for you to know about a hack the more damage it will do.It is crucial to be alerted as quickly as possible of a breach to your site. The longer it takes for you to know about a hack the more damage it will do.
    4. User Activity – Keeping a record of user activity in your WordPress security logs can be your saving grace after a successful attack. If you are monitoring the correct user activity, it can guide you through the timeline of a hack and show everything the hacker changed, from adding new users to adding unwanted pharma ads on your site.

    The good news is you can start monitoring security activity on your site with a plugin like iThemes Security. iThemes Security does all the work for you by tracking these important events on your site.

    13. Are you implementing these WordPress hardening measures?

    The WordPress platform gives you specific hardening measures to make your site a lot more secure from malicious hacks.

    These measures include:

    • Disable plugin installation
    • Reset WordPress salts and keys
    • Disable the file editor in themes and plugins
    • Enforce strong passwords
    • Implement 2FA (two-factor authorization)
    • Limit login attempts

    During the security audit, it’s important to check that this list of measures is fully in place. As an example, if you’re using a plugin that limits user login attempts and provides 2FA, take a look to see if the plugin is still working and is fully up to date.

    Also see if there may be better or more current plugin options available.

    Some hardening measures take a bit of technical knowledge to put into place. But if you’re using the iThemes Security plugin, you’ll be able to put the hardening measures into place with a few simple clicks.

    14. Are you using a WordPress security plugin?

    The last and final in your audit is to evaluate the security plugin on your site. So many of the tasks on this WordPress security audit list can be accomplished with a WordPress security plugin like iThemes Security.

    If you aren’t running a WordPress security plugin, it’s time to download and install one right away. An effective security plugin such as iThemes Security will do so much to protect your site from bots and hackers. Although there are a lot of different security plugins on the market, some are more effective than others.

    Take a look at this list of the features that an effective security plugin must bring to the table:

    • Malware scanning – Skilled hackers are constantly looking for vulnerable plugins. It’s important to use a security plugin that will run daily scans of your site while conducting deep checks and scans of every folder and file on your site, including the database.
    • Offsite scanning – You’ll use a lot of resources when you run a security scan. If the plugin you’re using utilizes your server, each scan may overload your WordPress site and make it grind to a halt. Find a security plugin that makes use of its own servers when it scans your website.
    • Login protection – Hackers will often try to attack your WP login page and attempt thousands of username and password combinations to gain unauthorized access to your site. This is called a brute force attack, and the security plugin you use either needs to block these attacks or hide your login page.
    • Security alerts in real-time – Whenever there’s any suspicious or malicious activity on your WordPress site, your security plugin needs to effectively detect it, then immediately let you know. You’ll then be able to take swift action to stop any damage.
    • Security activity log – An audit log will track each user’s activity on your website, including who has logged in, the details of repeated failed login attempts, and what function a user performed on your site. Having an activity log is useful when you’re trying to determine how your site was broken into or what updates were employed that caused a site malfunction.

    If you manage multiple WordPress sites and have decided on iThemes Security for your solution, make sure you also download and install the iThemes Sync plugin.
