Hello All,
Please, kindly find answers to your questions as to a security alert issue.
Does this also include the install zend php files ?
No, you may leave zend php files on your server. There is no need to remove them.
Unselect 'writable' priviliges for main folders.
My folders are WRITABLE for Owner only. Is that right?
Actually, it depends mostly on what type of owner you are. If you have complete root privileges (provided by your hosting provider), then you should leave 755 privileges, otherwise you won't be able to upload files via FTP. In this case no one except you won't be able to access your file(s) and make any changes there.
If you as an owner does not have root permissions, but rather an access, like www-data:www-data, then it is strongly recommended to unselect any writable permissions to avoid any hack attack. www-data - is just a sample name, it can be different for different systems, like: apache:apache - for FreeBSD, httpd:httpd - for RedHat, www-data – for Debian.
For example, with wxrwxr-x root:root - nobody except a root owner is able to change files, while with root:www-data -anyone from www.data group may access your files and edit them.
Therefore, it is advisable to check your owner's privileges and set necessary permissions for your folders, taking into account your server settings and owner’s privileges.
