I am trying to understand how giving 777 permission to folders or files works. I did some research and understand that 777 permission is not the best when it comes for security. Referring to Web application directories/files.
I do understand first sets of number which are the owners and groups, However I would like to clarify giving 7 permission to others. Who are the others, users within the server? Or anyone (even public users who access the website through the browsers)? And how others and what type of threat can others cause if the website folder/file had 777 permission?
And is there certain circumstances where it's ok to give 777 permission to folders/files, such as example of images, anything more out there?
