If you need to keep your blog secure or just want to make sure you are doing the most to keep website hackers at bay, you’ll want to review these Apache server settings to keep your content and website safe.
“CHMOD is a UNIX term for a server operation to set or change the mode of the file access permissions. When executed, the command can change file system modes of files and directories. The modes include permissions and special modes.”
If you click into the CHMOD Server Permissions website linked above you will be able to read what permissions should be used for which cases.
As a rule of thumb typical website pages should be a CHMOD of 644. Your blog’s wp-config.php file should be 600 or 660 to keep secure. The bottom-line on CHMOD is that using your FTP agent you can right click on any file or directory and change the file or access permissions. Make sure before you start changing things that you review CHMOD Explained and keep track of what you have changed so if need be you can revert back to a prior setting if needed.
