Securing Log Files
It is a good idea to move your log files from your Web servers to a more secure location. When you move these files, do it in a secure way. One way to achieve security is to use separate network lines that run directly from your staging environment to your production environment. This separate line is a good way to update content, and to move log files to secure servers. Another way to safely move log files is through Secure Sockets Layer (SSL) over HTTP or File Transfer Protocol (FTP).
If you use pipeline logging to debug a pipeline, be aware that sensitive information may appear in clear text in the log files. Make sure you secure the folder that contains these pipeline log files (by default, the \Pipeline\Logfiles folder in the application).
