Using folder path instead of file path while opening a file.Primarily these are the reasons of permissionerror: errno13 permission denied in Python – Reasons of permissionerror ERRNO 13 in Python And trying to access that will result in permission error: permission denied. The password file won’t have any permission in others category. People use to give least permissions to the others because these are the access levels for everyone. Now you are into others user category because you are not the owner of the file and probably not the part of group. Let’s get back to our password file example. So, you can assign 3 sets of permissions, like this – UserĪn account of system who we want to separately assign permissionsĪ set of multiple accounts, software, processes who can share the same permissions Now the question is, how to apply these permissions to different software, users etc.? Well there are 3 types of users – owner, group, and others. Similarly, with write permission they can write to the file. With read permission a software, process, application, user etc. There are 3 types of permissions – read, write and execute. That’s why sudo should be used with caution. A software running with root privilege can access your password file which you wanted to be secure. So, we seldom use the root account otherwise there is no meaning of security. In a system, root user can access everything. That’s why you will restrict it from other applications, software, processes, users, APIs etc. For example, you have stored username & password for your database in a file so you never want it to be accessible to anyone except the database application and you. Permission denied on files to protect them. This is because you don’t have permission to read the content of that file. Strangely another user can open the same file.
