Provenance and attestations for file system permissions are crucial for ensuring data integrity and security in a DevOps environment. By maintaining a clear record of permissions and their changes, organizations can trace actions back to their origins.
<?php
// Example to Set Up Filesystem Permissions with Provenance
$filePath = '/var/www/html/testfile.txt';
// Function to log permissions changes
function logPermissionsChange($filePath) {
$currentPermissions = substr(sprintf('%o', fileperms($filePath)), -4);
$entry = date('Y-m-d H:i:s') . " - Permissions for $filePath changed to $currentPermissions\n";
file_put_contents('/var/log/permissions.log', $entry, FILE_APPEND);
}
// Set the permissions
chmod($filePath, 0755);
// Log the change
logPermissionsChange($filePath);
?>
