In order to set directory's security, use the following snippet:

DirectoryInfo directory = new DirectoryInfo(dirPath);
DirectorySecurity security = directory.GetAccessControl();
security.AddAccessRule(new FileSystemAccessRule({ftp server user\'s sddl}, FileSystemRights.FullControl, InheritanceFlags.ContainerInherit, PropagationFlags.None, AccessControlType.Allow));
directory.SetAccessControl(security);
directory.Refresh();
