Question

In a traditional UNIX file access model, the system provides a default setting for newly created files and directories, which can be changed by the owner later. The default is typically full access for the owner combined with one of the following: no access for group and others (case 1), read/execute access for group and none for the other (case 2), or read/execute access for both group and other (case 3). Briefly discuss the advantages and disadvantages of each of these cases, including an example of a type of organization where each would be appropriate. Also, give the equivalent numeric value of access control for each case.

Explanation / Answer

By default the files or directories which are created will get the full permission the owner who created that file need to set the permissions for the file.

The first case here is no access for group and others

The second case is read/execute access for the group none for the other

The third case here is read/execute for Both groups and others.
