Platform: CentOS7
Scenario: You've been directed by you supervisor to create a secure directory structure for the sales and account groups. The requirement she has given you are below.
1. Set up a shared group environment. Create two directories: /data/account and /data/sales. Make the group sales owner of the directory sales, and make the group account owner of the directory account.
2. Configure the permissions so that the user owner (which must be root) and group owner have full access to the directory. There should be no permissions assigned to the others entity. Also, make sure that "others" will get no permissions on newly created files and directories within the entire /data structure.
3. Create a configuration that allows members of the group sales read files in the directory /data/account. Also, make sure that members of the group account have read permissions in the directory /data/sales.
4. Ensure that all new files in both directories inherit the group owner of the /data/sales and /data/account directory. This means that all files that will be created in /data/sales will be owned by the group sales, and all files in /data/account will be owned by the group account.
5. Ensure that users are only allowed to remove files of which they are the owner.
