Office provide me specific requirement. Below is the detailed requirement:
1.Restriction for "su -" to Root:
a.There is a normal user account named "dummy1234".
b.This user should not have permission to use the command "su -" to switch to the "root" user.
2.Permission to "su -" to Oracle:
a.The same user, "dummy1234", should only be allowed to use the command "su -" to switch to the "oracle" user.
The goal is to ensure that "dummy1234" has limited access and cannot become "root" but can still access the "oracle"
user account as required.
Please provide me with a step-by-step action plan asap.
