What chmod is needed for site folders and files for security and normal functioning?

Answer 1

Yevgeny Samsonov is almost right - the minimum possible. If we are talking about a web server, then reading for those directories / files that it needs.
If you need to download files - then the right to write to a certain directory, but with the prohibition to execute scripts from this directory.
Details are needed to answer more specifically.
