WordPress Security Audit: Checklist & Best Practices

With over 810 million websites running on WordPress, its impact cannot be underestimated in the present times. However, such popularity also attracts cybercriminals who are ready to take advantage of outdated plugins, weak passwords, or misconfigurations. Performing regular WordPress security audits will reveal such issues at an early stage, hence avoiding any compromise through attacks or leakage of sensitive information. However, several businesses are unaware of how a detailed audit can help them and align compliance requirements with real-world protection.

In this article, we explain what a WordPress security audit is and how WordPress sites have become vulnerable to plugin attacks. We also present the importance of regular WP audits and the functions of XSS and CSRF in penetration in detail. Next, we describe key objectives, the importance of WP security audit log data, and the step-by-step auditing plan. In this article, you will learn about the WordPress site security audit checklist, common issues, recommendations, and how SentinelOne enhances it.

What is a WordPress Security Audit?

A WordPress security audit is a systematic examination of the fundamental structure of your site, theme, and plugins to identify vulnerable points that a hacker may use. According to the statistics, 90% of WordPress security issues are in plugins, while 6% are in themes and 4% in the core software. This highlights the importance of systematically reviewing each layer, particularly user permissions, code versions, and server configurations. An effective auditing strategy combines a scanning tool with manual reviews and log files to provide a comprehensive picture of the site’s security.

Whether you are the owner of an online store or a blogger, infiltration attempts are likely to exploit certain patterns, including unpatched code and old admin credentials. With such audits in place, you are well-updated on new threats that are likely to occur within the shortest time, making your site relatively secure.

Need for WP Security Audit

Cross-site scripting remains a major threat, contributing to 50% of all the plugin vulnerabilities, while cross-site request forgery contributes to 15%. These statistics alone show how easily infiltration can happen if site owners do not pay attention to scanning or patching.

Even though WordPress is easy to use, hackers exploit outdated updates or ignorant staff actions to access the admin panels. In the following section, we discuss four primary reasons why a regular WordPress security audit is still crucial.

1. Combating Ransomware and Data Loss: While traditionally, ransomware is used to infect endpoints, it can also target any type of website and encrypt databases or lock admin panels. Hackers can take advantage of an outdated plugin or a compromised login page to inject malicious scripts. In the process of security WordPress website audit, you can see what to fix or remove immediately due to known vulnerabilities or malicious code. Therefore, by quickly establishing infiltration angles, you minimize the chances of ransom extortion or stolen users’ data.
2. Upholding Trust & Brand Reputation: If your site deals with personal data or performs transactions, infiltration can lead to data leakage or stolen credit card numbers. It is also very expensive to regain the trust of users after such an incident, including public relations and potential legal expenses. Conducting a regular WordPress security audit also increases user credibility as it ensures that the utmost security is provided for their data. In the long run, safe user experiences lead to brand loyalty and, therefore, a competitive advantage over other businesses.
3. Maintaining Regulatory & Industry Compliance: Online stores need to meet the requirements of PCI DSS or data security standards. A WordPress website security audit also checks whether encryption is used, what privileges users have, and logging activity, all of which is related to compliance. If infiltration happens, the documented measures on your site lower the possible fines or reputation damage. This synergy ensures that the WP practices adopted are in line with the general industry practices and strengthens your legal position.
4. Preserving SEO & Site Availability: Malicious script injections or domain blacklisting by search engines can severely affect your SEO and, thus, your traffic. Google marks such sites as malicious, demoting them in search rankings or displaying warning messages when a user attempts to visit the website. With a structured audit routine, you are able to identify attempts at infiltration that compromise site performance or content. A stable and secure site encourages users to stay and be active on the site, hence ensuring steady progress in the long run.

Key objectives of a WP Security Audit

Instead of just looking for plugin updates, an effective WordPress security audit aims at other objectives, such as checking on the user controls, integrity of the code, and real-time detection, among others.

Here are five key assessment goals that are the foundation of a comprehensive site assessment process: All of them contribute to preventing infiltration, protecting brands, and ensuring compliance with established security standards.

1. Confirm Plugin & Theme Integrity: Malicious or unverified plugins are still the most common entry point, especially if they are obtained from untrusted sources. Auditors identify the plugin’s originality, using official repositories or checking the reputation of the developers. This synergy also involves the search for remaining or “nulled” plugins that contain code that is malicious in nature. In the long run, constant plugin curation minimizes the time that criminals spend penetrating into the system.
2. Assess User & Role Management: Privileges granted or admin accounts that remain open for longer increase the chances of infiltration should passwords be compromised. Auditors confirm that their role is consistent with user responsibilities, as well as strong passwords. This way, staff or external contributors cannot install rogue plugins or change other files on the site without permission. Additional layers in the form of multi-factor authentication for admin or critical roles reduce infiltration attempts even further.
3. Verify Logging & Monitoring Configuration: Real-time monitoring requires identifying proper events—logins, file changes, and plugin updates. A properly structured WP security audit log shows the signs of infiltration or brute force attack, enabling quick action. Auditors verify that logs are detailed, kept for the right amount of time, and linked to alerting mechanisms. Unfortunately, logging, if not properly implemented, can be easily bypassed and an intrusion can go unnoticed until there has been a large data or SEO loss.
4. Evaluate Backup & Recovery Procedures: Even the best defense measures cannot prevent some hackers from penetrating the system – that is why site backups are crucial when criminals lock or modify the files. Auditors verify the backup schedule, offsite or cloud storage, and test restore procedures. This synergy saves site owners from panicking in case of infiltration leading to encryption or site defacement. This way, the backup set is always checked for functionality and updated if necessary to meet the defined standard.
5. Review Server & Hosting Security: WordPress security covers not only the content management system but also the server, .htaccess, or a firewall. Auditors may scan for hosting logs, the state of OS patches, or containers for infiltration vectors. It also provides the synergy to ensure your environment is locked down, such as in the directory indexing or file editing. This multi-layered approach combines WordPress scanning with more general hosting security measures, protecting it from the inside and the outside of the application.

WP Security Audit Log: Why It Matters

A clear WP security audit log serves as your site’s black box that tracks each specific change in the file or an admin activity. When infiltration takes place, it identifies who altered code, installed malicious plugins, or spammed a large number of people.

In the following points, we will explain why logs are an essential component of WordPress defense strategies:

1. Real-Time Intrusion Detection: It is easier to detect infiltration while it is in progress if you monitor activities such as logging of sensitive files or repeated attempts to log in as an administrator. It means that through tools or plugins, instant notification can be provided if the critical thresholds, such as failed login attempts, are crossed. This synergy contributes to a small dwell time of infiltrators, enabling the staff to contain affected accounts easily. In the long run, refining these triggers results in the identification of fewer false positives, more specific to actual infiltration indications.
2. Compliance & Forensic Analysis: Some regulations necessitate that proper evidence is provided that shows that data manipulations have been done and are traceable. In the case of infiltration or data theft, logs show how the intruders got in or out of the records. This synergy serves to justify potential legal actions or insurance claims by presenting a timeline of the infiltration steps. In the absence of logs, penetration analysis is often a best-guess scenario, which means that the attacker can penetrate your system time and again.
3. Tracking Content & Plugin Updates: Apart from infiltration detection, logs capture ordinary site changes, such as new pages, plugins, or theme modifications. This makes it easier to define who introduced new functionality to the code or who initiated a theme conflict. In case of infiltration, it is possible to determine whether the staff made changes to the code or an attacker inserted malicious scripts. In multiple cycles, logs provide information about user behaviors that can be beneficial for the developers in terms of streamlining particular workflows while ensuring the security of the system.
4. Building a Culture of Accountability: When employees are aware that every move is being recorded, it makes them more careful with actions like making hasty plugin modifications or simply clicking ‘ignore’ on the notifications about new patches. This encourages awareness across the site as dev teams use logs to consult or check on each other’s activities. It also allows auditors to determine the training needs of staff—such as misconfigurations that are recurring due to a lack of awareness. The result is a site environment that is systematically designed to counteract infiltration angles.
5. Prompt Incident Response & Recovery: In case of infiltration, logs help in identifying the cause – was it a user or a script that initiated the change? If staff can identify infiltration points early, they can undo the changes or fix other areas that were missed before further damage occurs. This synergy reduces the sizes of recovery windows significantly, thus reducing any downtime or impact on the users. In the long run, logging aligns with well-documented restoration steps, creating strong operational resilience over time.

WordPress Security Audit: Step-by-Step Guide

A systematic approach allows not a single critical aspect, such as file permissions or plugins’ legitimacy, to be overlooked. In this way, the processes of scanning, logging, and proactive patching are linked as one cycle.

Below, we describe five crucial activities that characterize a comprehensive WordPress security audit, linking each to remediation steps:

1. Inventory Plugins, Themes, & Versions: Start by listing all the plugins, themes, or any of the custom codes you have installed, ensuring that the versions are up-to-date with the official ones. This synergy allows you to identify possible approaches for infiltrating the system, as older plugin versions are particularly vulnerable to attacks. By checking the official release notes, you verify whether there are security updates available or new CVEs are identified. In the long run, steady inventory leads to small patching intervals and low infiltration opportunities.
2. Check User Roles & Password Policies: Adopt the ‘least privilege’ principle, which means only those who must have administrative rights on the PC must be given such rights. Ensure that the passphrase is strong or confirm the use of multi-factor authentication, especially for site administrators or any other special user. This synergy minimizes the chances of an attacker gaining access to the system in the event that they compromise user credentials. At the same time, searching for unused or trial accounts does not allow unlawful individuals to crack the previous account data.
3. Run Automated Vulnerability Scans: Use additional tools such as Wordfence, Sucuri, or specific scanners for a more comprehensive code scan. They point out code injection attempts, unprotected directories, or known vulnerabilities in your plugin set. This synergy works in parallel with real-time scanning if you have installed a WordPress audit plugin that tracks changes. A document discovered issues in your WordPress website audit logs, ranking them by severity for immediate fixes.
4. Manually Inspect Theme & Config Files: Automation is useful, but there can be more subtle attempts at infiltration or scripts that can only be detected with manual analysis. Search for any lines that contain references to external domains in the theme’s function.php or in the code of a custom plugin. This synergy guarantees that techniques such as backdoors that are coded to evade scanners remain evident under scrutiny. Periodically, staff or specialized auditors improve these reviews, progressively eliminating infiltration angles.
5. Evaluate Logging & Backup Readiness: Last but not least, ensure a reliable logging system, such as the WP Security Audit Log, to track all admin activities, plugin updates, or file changes. Backups should be created, tested, and stored on different media. This integration enables the detection of infiltration and the recovery of any data that might be encrypted or sabotaged within the site’s contents. In the long run, the cycle of scan, fix, and re-check reinforces infiltration resilience.

WordPress Website Security Audit Checklist

Having a short reference list can help site owners benefit from the step-by-step WP website security audit process without missing any step. Using a checklist helps define each task—such as checking for SSL or removing debug code—during recurring audits.

Here are five fundamental activities that can help you strengthen infiltration prevention and bring your process in line with industry standards:

1. Check for WordPress Core and Plugin Updates: Make sure that you are using the latest stable version of WP, as older builds contain numerous infiltration angles. Search for available updates in the plugin library and compare them with the official changelog or security notices. This synergy deals with the 90% increase in vulnerability from either outdated or malicious plugins. In the long run, regular updates become a habit that reduces the likelihood of infiltration by half.
2. Compulsory Password Changes for Administrative and Key Account Passwords: While staff may insist on robust passphrases, schedule resets minimize the chances of hacks exploiting leaked credentials. Implement password change with 2FA for site owners or contributors whenever possible. This synergy is particularly important, especially when there is a leakage of big data or rumors of infiltration. Integrating forced resets into your practice keeps your system less vulnerable to infiltration, as criminals cannot rely on old credentials.
3. Scrutinize .htaccess & wp-config.php: There are certain WordPress config files that should not be modified. For this reason, ensure that their permissions are set in a way that only root can write to them and other users cannot have any read permissions either. This synergy also helps to disable the modification of database credentials or enable debug modes that expose the site structure to attackers. Ensure that the server logs any effort to tamper with these file permissions. When combined with regular scans, the angles of infiltration through misconfigurations are quickly eliminated through the integration of effective file system controls.
4. Validate SSL/TLS & DNS Settings: Ensure that your site is secure by implementing HTTPS and ensure that all the traffic is redirected from HTTP. Scan your DNS records for missed subdomains or testing sites that might be exploited by criminals. This synergy ensures that any attempts at man-in-the-middle or domain clone infiltrations are kept to the barest minimum. Across the cycles, you align the domain, subdomain, and certificate to ensure brand reliability.
5. Check Backup’s Integrity & Restoration Times: Do not simply rely on the mere existence of backups—perform partial or full site restorations at least on a quarterly basis. Even if infiltration occurs or an unscrupulous plugin compromises the data, immediate restoration becomes essential. This synergy minimizes the time that the organization experiences downtime or loses data, thus reducing the effects of infiltration. Thus, by tracking restoration times, you improve the readiness of your site to handle fallbacks, even if it is under stress.

WordPress Website Auditing Challenges

Actual world challenges make simple routine WordPress audits a challenging task. From plugin conflicts to staff resource constraints, each obstacle may be accompanied by missed infiltration angles.

Here, we outline five common pitfalls—and how site owners can effectively counter them for better infiltration prevention.

1. Plugin & Theme Conflicts: Plugins, such as security scanners or advanced functionality plugins, may interfere with the existing code and lead to the site’s failure or display distortions. Employees could also intentionally or unintentionally block or disable key scanning features to ensure the site is stable, as this creates openings for infiltration. This synergy requires a testing environment to be established before the product is pushed to the production stage. In the long run, dev-ops collaboration ensures that the scanning cycles are synchronized with stable site performance.
2. Inconsistent Staff Expertise: While large enterprises may employ a dedicated security team, small or medium-sized sites may only have one developer or a marketing employee. Lack of proper knowledge may result in cases where an attacker could be fully infiltrated into a system and yet be left unnoticed due to the lack of further infiltration checks or when a system administrator could simply dismiss logs that look suspicious. This synergy creates openings that criminals take advantage of by attacking vulnerable systems with unpatched or wrong configurations. The shortage of skills is addressed by either investing in training to develop them internally or obtaining external auditing resources.
3. Host-Level Restrictions or Shared Environments: Users of shared hosting are likely to have restricted file access or the ability to log into the server. This interaction makes it even harder to perform advanced scans or custom plugin usage for infiltration detection. Restrictions set by the host limit the effectiveness of the WordPress website audit strategy. Possible solutions are to switch to a managed WordPress hosting or a private server, where the server level can be scanned more thoroughly.
4. Time & Budget Constraints: Scanning and updating of plugins or code reviews consumes staff hours, especially if the site has many plugins. Some owners are more focused on the creation of new features than on ways to prevent infiltration until they are hit by an attack. This makes it easier for criminals to infiltrate because they can easily identify programs with unpatched or outdated codes. Having monthly or quarterly audits or implementing automation is a good way to find a balance between the speed of development and site vulnerability.
5. Rapid Threat Evolution: Cybercriminals always learn or improve new infiltration techniques or methods, such as a new plugin vulnerability or a way to attack WordPress login credentials. A comprehensive audit performed two months ago may not identify new vulnerabilities that have been introduced in the meantime. This synergy requires fast scanning, feed, and micro-updates in a short time frame. Through successive phases, site owners strengthen their mechanisms to detect infiltration, adapting themselves at the same rate as the criminals.

Best Practices for WordPress Security

The best approach to implementation is to establish some guidelines to ensure that the angles of infiltration remain small and constant regardless of changes in site size or technology.

However, no approach can provide complete protection, and therefore, the best approach is to employ multiple layers to strengthen security. Here are five WordPress security best practices that integrate scanning, users, and a zero-trust approach:

1. Enforce the Principle of Least Privilege: Restrict administrative permissions to only the necessary personnel while assigning user roles and their permissions. This synergy reduces the chances of the attacker achieving infiltration if they get hold of a staffer’s credentials—privileges are limited. Eventually, roles get fine-tuned to fit the need, and every plugin or contributor account is aligned with necessity only. This makes WordPress inherently less vulnerable to infiltration attempts in the first place.
2. Adopt a Web Application Firewall: WAF services or plugins act between the WordPress core and the traffic, preventing dangerous IP addresses or injections. The synergy combines real-time scanning with known infiltration patterns, significantly reducing the success of the exploit. In many cycles, WAF learns from activity and improves the ability to recognize infiltration. Combined with a good server-level firewall, the site receives an additional layer of protection against infiltration threats.
3. Implement Multi-Factor Authentication for Admins: Ineffective or forced passwords continue to be one of the primary entry points for attackers. By requiring MFA for privileged accounts using an authenticator app or a text-based code, you slow down stolen credential usage. This synergy combines long and powerful passphrases with short-lived verification codes to prevent intruders from getting in. This measure is especially important for site owners, devs, or finance staff who work with sensitive site or user data.
4. WP Security Audit Log to Track Activity: An ideal WP security audit log plugin records each modification to a file, new registration of a user, or installation of a plugin. This synergy facilitates early detection of such infiltrations to allow the staff to identify such activity or multiple failed login attempts. From the usage patterns, you determine that the staff requires training or that there is a conflict with the plugin. In the long run, such a measure creates a stronger infiltration prevention approach and less confusion after the attack.
5. Regularly Test Backups & Restoration: In case of infiltration or site meltdown, the immediate course of action that is required is to revert. Ensure that backups are created at least daily or weekly and stored off-site. Also, perform partial or full restores periodically. This synergy ensures that any attempt to infiltrate the system and lock or corrupt data is a short-lived endeavor. Furthermore, checking the backups after significant site changes or after a new plugin installation strengthens stable rollback procedures.
