File change detection in iThemes Security Pro just added a new feature: online file comparisons. This new setting works to compare changes made to any WordPress core file on your system with the version on WordPress.org to determine if the change was malicious.
Currently, this feature only works with WordPress core files and plugins. WordPress.org themes will be added when checksum support is available.
The online file comparisons will compare changes made to iThemes plugins and themes to versions in the iThemes repository.
The Importance of File Change Detection for your WordPress Site
If someone manages to get into your site, they’ll probably add, remove or change a file. File change detection in iThemes Security allows you to know if files have changed in your WordPress installation so you can verify if the changes were actually made by you.
If changes were made to any of your site’s files, iTheme Security will email you. File change history is also available from the Logs Page in the plugin menu.
Benefits of Online File Comparison
Comparing file changes against the current WordPress core source files creates more accurate file change detection. For example, if you upgrade to WordPress core, you’ll no longer see file change notifications from iThemes Security, so it greatly prevents false positives. Now, you’ll only get a file change notification if your files differ from the WordPress core version on WordPress.org.
Enable Online File Comparison with One Click
