Week 2 – Security Planning & User Management
1. Security Strategy
This week focused on implementing the Principle of Least Privilege. By creating a dedicated user for administration and restricting ‘root’ usage, we ensure that the system is more secure against accidental or unauthorized changes.
2. User & Group Implementation
I performed the following terminal operations to configure the server’s user environment.
A. Creating the Administrative User
I created the zetzura account to serve as the primary system administrator.
- Command used:
sudo adduser zetzura
B. Granting Sudo Privileges
To allow the new user to run administrative tasks, I added them to the sudo group.
- Command used:
sudo usermod -aG sudo zetzura - Verification command:
groups zetzura
C. Removing Temporary Accounts
To reduce security risks, I removed the manager account that was used during the testing phase.
- Command used:
sudo deluser --remove-home manager
D. Final System Audit
I performed a final check to ensure the user list and group permissions were correctly applied.
- Command used:
getent group sudo
