This section has learners prepare password data for testing, using Linux command-line, by manipulating permissions, writing unmasked passwords, and feeding Johnny password values to use in its cracking attack. You will need to do additional preparation, covered in the next section, to read and write password data. You learn that creating a user and a password must be done separately, and password values remain hidden from view. Then you use the 'useradd' and 'passwd' commands to create data for Johnny to test. In this section, you log into the lab's virtual Kali Linux machine. Next, you test the security of the passwords in Linux by using John the Ripper. First, you create five local users in Linux, and then you configure passwords for the users. You need to audit passwords to ensure that users are creating secure passwords. You are a Linux systems administrator responsible for password security.

Finally, executing an attack with the Johnny application will inform beginners about the utility configuration, how to run and stop an attack, and how to view and interpret the results. Knowledge about unmasking passwords and setting up to test their strength, using Linux commands, will help develop troubleshooting and data quality testing skills.

Enforcing good password creation and using a command-line interface to set up new accounts will give learners a fundamental skill in managing computer systems.

Understanding password vulnerabilities and how to check for weak ones make for critical skills in many IT professions, including CyberDefense, CyberSecurity, and System Administrator roles. Learners enter commands in Terminal and use the John the Ripper general user interface (GUI) to complete tasks in Kali Linux. You can, however, attempt the lab more than once if needed.

Participants will need to set aside a full 30 - 45 minutes to complete the virtual lab, as users will not be able to return to the lab mid-way. Lab exercises will include creating Linux users and passwords at various security levels, manipulating user accounts, permissions, and text files to verify password security and running attacks using the Linux utility.īeginners who do not have any Linux experience can start right away with the lab. This virtual lab makes up the fifth one in the Cybersecurity: Offensive Tools - Challenge Series. Learners will gain hands-on-experience preparing and conducting password audits using a Linux utility called John the Ripper (Johnny).
