# Introduction In Unix-like operating systems, setuid (set user ID) is a special file permission that allows a user to execute a file with the permissions of the file's owner. While this can be useful for certain system operations, it can also pose security risks if misused. In this challenge, you'll learn how to identify and list all setuid files on a system, which is an essential skill for system administrators and security professionals. ## Environment LabEx uses Red Hat Universal Base Image 9 (UBI9) to simulate the exam environment. It may not be identical to the actual RHCSA exam environment, but it provides a good representation of the tasks you'll encounter. There are two users in the environment: - `labex`: A standard user with sudo privileges, password: `labex`. - `root`: The system administrator, password: `redhat`. The challenge features real exam questions, along with explanations, requirements, and automated verification scripts to help you confirm task completion. It effectively simulates the knowledge areas covered in the RHCSA exam.
