Who receives incident reports for sudo users and how to access them?

Ubuntu 1

In the world of Linux, sudo (SuperUser DO) is a powerful command that allows users to execute tasks with the security privileges of another user, typically the superuser. When a non-sudo user attempts to run a command using sudo and fails, an incident is reported. But who receives these incident reports and how can they be accessed? Let’s delve into this topic.

Quick Answer

The incident reports for sudo users are not sent to an external entity but are logged locally on the system. The specific location of these logs can vary depending on the system’s configuration. On Ubuntu-based systems, incident reports are redirected to /dev/null, but logs related to sudo commands can be found in the /var/log/auth.log file. Additionally, the journalctl command and the GNOME Logs application can also be used to access these reports.

Understanding Incident Reports

Incident reports are generated when unauthorized users attempt to run sudo commands. Contrary to what some might think, these reports are not sent to an external entity. Instead, they are logged locally on the system. The specific location of these logs can vary depending on the system’s configuration.

Accessing Incident Reports on Ubuntu

On Ubuntu-based systems, incident reports are not stored in the /var/spool/mail/root directory as one might expect. Instead, they are redirected to /dev/null, effectively discarding the report. However, logs related to sudo commands can be found in the /var/log/auth.log file. This file contains a detailed log of authentication-related events, including sudo incidents.

To view the log entries, you can use the command sudo cat /var/log/auth.log. Here, sudo is used to run the command with administrative privileges, cat is a standard Unix utility that reads files sequentially, writing them to standard output, and /var/log/auth.log is the path of the file you want to read.

Using the journalctl Command

An alternative method to access sudo incident reports is by using the journalctl command. This command is used to query the contents of the systemd journal. By running journalctl /usr/bin/sudo, you can list all messages related to the sudo executable path. The reported incidents will be highlighted in red for easy identification.

The -f option can be used with journalctl to follow the journal, similar to tail -f. Running journalctl -f /usr/bin/sudo will continuously print new entries as they are appended to the journal, which can be useful for monitoring recent incidents.

Using the GNOME Logs Application

For those using recent Ubuntu releases, the GNOME Logs application is another option for accessing sudo incident reports. By opening the application, selecting “All” from the categories list, and searching for “sudo”, you can find incidents related to sudo commands.

However, it’s important to note that this method lacks the highlighting feature of journalctl, which can make it harder to spot the incident reports among other log entries.

Conclusion

In conclusion, sudo incident reports are not reported externally but are logged locally on the system. You can access these reports by checking the appropriate log files or using tools like journalctl or GNOME Logs, depending on your system’s configuration. By understanding how to access and interpret these reports, system administrators can better monitor and manage the use of sudo commands on their systems.
