WordPress File Permissions: The Foundation of Site Security
WordPress file permissions are the rules that control who can read, write, or execute files and directories on your website’s server. These permissions are essential because they determine how users and processes interact with your WordPress files, directly impacting your site’s security.
Most WordPress sites run on Linux or Unix-based servers, which use a permission scheme involving three types of access: read (r), write (w), and execute (x). These permissions apply to three categories of users: the file owner, the group, and others (everyone else).
For example, a permission setting of 755 means the owner has full access (read, write, execute), while the group and others have read and execute permissions but cannot modify the file. This setting is common for directories, allowing users to list contents and access files without changing them.
Files typically have permissions set to 644, meaning the owner can read and write, but group and others can only read. This prevents unauthorized modifications while allowing necessary access.
Using overly permissive settings like 777 (read, write, execute for everyone) is dangerous because it lets anyone modify your files, opening doors for hackers to inject malicious code or deface your site.
File permissions work hand-in-hand with WordPress user roles and access control. Even if a user has admin rights within WordPress, improper file permissions can allow unauthorized system-level access, bypassing WordPress’s internal controls.
Properly configured file permissions help maintain compliance with security standards and reduce risks of data breaches, unauthorized changes, and malware infections.
The IT Audit Framework for WordPress File Permissions
An IT audit focused on WordPress file permissions is a systematic review process aimed at identifying and mitigating risks related to file access and modification. The primary objectives include managing risk, ensuring compliance with policies and regulations, controlling access, and assessing vulnerabilities.
This audit process is risk-based and systematic, meaning it prioritizes areas with the highest potential impact and follows a structured approach to cover all critical components.
Combining manual inspection with automated tools ensures thoroughness. Manual reviews allow auditors to understand context and nuances, while automated scans quickly identify common misconfigurations and vulnerabilities.
Audit logs and file integrity monitoring are invaluable for ongoing security. They record changes to files and permissions, enabling quick detection of unauthorized activity and supporting forensic investigations if needed.
Overall, the audit framework helps organizations maintain a secure WordPress environment by continuously assessing and improving file permission settings.
Step-by-Step Process to Audit WordPress File Permissions
Before starting, always back up your WordPress site and document your current configuration. Having a restore point is critical if changes cause issues.
Identify critical files and directories such as wp-config.php, wp-content, wp-includes, and plugin/theme folders. These locations often contain sensitive data or executable code.
Manual inspection can be done using command-line tools
ls -llists files with permissions and ownership.chmodchanges permissions.findhelps locate files with specific permission settings, e.g.,find /path/to/wordpress -perm 777to find dangerous permissions.
Automated scanning tools and security plugins like Wordfence, Sucuri, and Website Security by CleanTalk provide user-friendly interfaces to scan for insecure permissions and other vulnerabilities. They often include recommendations and automated fixes.

Review server user and group ownership to ensure files are owned by the correct user running the web server, preventing privilege escalation.
Pay special attention to wp-config.php, which contains database credentials and secret keys. It should have strict permissions (600 or 640) to prevent unauthorized reading.
Document all findings, categorize risks by severity, and prioritize remediation efforts accordingly.
How to Secure WordPress File Permissions Effectively
Start by applying secure default permissions: directories at 755 and files at 644. This setup balances accessibility and protection.
For sensitive files like wp-config.php, tighten permissions to 600 or 640, limiting access to the owner and possibly the group.
Lock down PHP scripts and executable files by restricting write permissions and, if possible, setting them to 640 to prevent unauthorized execution.
Disable file editing from the WordPress dashboard by adding define('DISALLOW_FILE_EDIT', true); in wp-config.php. This prevents attackers from modifying files if they gain admin access.
Manage user roles carefully, applying the principle of least privilege — users should only have the permissions necessary for their tasks.
Enforce strong authentication practices, including complex passwords and two-factor authentication (2FA), to reduce the risk of credential compromise.
Use .htaccess and server-level configurations to restrict access to sensitive files and directories, blocking unauthorized HTTP requests.
Automate permission management with security plugins and hosting features that monitor and correct insecure settings.
Keep WordPress core, themes, and plugins updated regularly to patch vulnerabilities that could be exploited despite correct permissions.
Integrating File Permission Audits into a Broader WordPress Security Strategy
File permissions are one layer in a multi-layered security approach. Integrate permission audits with broader IT audit programs covering network security, application security, and compliance.
Monitor file changes continuously using audit logs and file integrity monitoring tools. This helps detect suspicious modifications early.
Conduct vulnerability assessments beyond permissions, scanning for SQL injection, cross-site scripting (XSS), malware, and other threats.
Ensure compliance with industry standards like PCI DSS or HIPAA, which require strict controls over data access and system integrity.
Plan and test backups and recovery procedures to quickly restore your site if files are compromised.
Consider hosting platforms with enhanced security features, such as Pantheon, which offer automated updates, server-level isolation, and proactive monitoring to strengthen your WordPress security posture.
