I’m performing a security audit on a Linux system and one of the tasks is to enumerate all users and identify any potential issues with user permissions or accounts that may pose a security risk. I know the /etc/passwd file contains user information, but I’m not sure if there are other Bash commands that can help me gather more detailed information, such as user groups, last login times, or password settings.
What Bash commands can I use to efficiently enumerate users and check for weak spots in user account security? Any additional tips on what to look for in user enumeration would also be appreciated.
