Unix-like systems, such as Linux, allow for a single user account called root that has complete access to the system. After logging in as root, you are then able to create secondary user accounts. These secondary users have limited access and should only be used for tasks that do not require full system access. After creating these secondary user accounts, it is important to remember to log in as one of these users instead of using the root account directly. This is done to protect yourself from making mistakes and to limit your exposure to potential security risks. ..
Steps to check sudo Command Usage on Linux
Authentication Log
sudo journalctl -u username -o json | grep “Command” This will give you a list of all the sudo commands that were run by username, along with the time and date that they were run. ..
If you are using a distribution that uses a different location for the log file, you can check it by running the following command: sudo ls -l /var/log/secure | grep audit
Making Sense of Chaos
The log file will likely contain a lot of entries that are not of interest. You can browse and scroll through it or use the search function of your text editor to find any mention of sudo. ..
sudo grep “sudo” logfile Step 2: If you want to see all the commands that were run as a result of a sudo command, use the -c option: sudo -c logfile ..
If you are using a distribution other than Ubuntu, remember to update the path to the log file in your /etc/logrotate.d directory. ..
-e “C:\Users\username\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup”
-R “C:\Users\username\AppData\Roaming\Microsoft \Windows \Start Menu\Programs\Startup”
When you check the computer out, you’ll find a series of entries that contain the date, time, computer name, and command used. ..
Normal Bash
ls -l This would list the contents of the “.bash_history” file. ..
To run the commands in the terminal, type: ls -l or cd /usr/local/bin
Journalctl
Step 2: To start journalctl, type the following command: sudo journalctl -f Step 3: In the output of journalctl, you will see a list of all the commands that sudo has run. This includes commands that have been executed as the root user, as well as commands that have been executed with your user account. ..
This is true for many popular distributions, including Debian and Ubuntu, as well as Arch Linux and Fedora. Journalctl can be helpful if you are constantly switching between systemd-based Linux distributions. ..
To view the sudo logs, you first need to log in as either the root user or an account with superuser privileges. To do this, you can use the following command: journalctl -u root journalctl -s sudo
sudo logs -l
GUI-specific Programs
If you want to monitor your system, you can use a special interface that came with your desktop environment. This way, you’ll reduce the complexity and number of commands you need to learn. Additionally, these programs are always included in a basic installation of a desktop environment, but may not be included in a Linux distribution’s build. Therefore, it is important to first check if these tools are already installed on your system. ..
GNOME Log
GNOME Log is the default system logger for distributions that use the GNOME desktop environment. This includes Ubuntu 21.10, 22.04 as well as Fedora 36.
Step 2: Once you have found the GNOME Log Utility, you will need to open it. To do this, double-click on the icon located in the System Tray. Step 3: Once the GNOME Log Utility has been opened, you will need to select the “Logs” tab. From here, you can select the logs that you want to view. ..
Once open, the program will present a number of tabs where you can check the log for a particular aspect of your system. To check for your sudo logs, you will need to click “Security”. ..
This will print out all of the latest security information for your machine, including all of the processes that ran with root privileges regardless if it is using sudo or not. From here, you can then press the Magnifying Glass icon on the top right corner of the window to initiate a search on all of these log entries.
To restrict the output of GNOME Logs to only those commands and processes that were run through sudo, type the following command: sudo. ..
Final Words
Super User Do is a command that allows the super user to execute commands with high privileges. When we prefix the command along with other commands, this command is executed with high privileges. This means that the user with the appropriate privilege can run a command like other users. This is equivalent to the “run as administrator” option in Windows. ..
