What you need to know

Preparation

Red Hat encourages all candidates for the Red Hat Certified Specialist in Security: Linux credential to consider taking Red Hat Security: Linux in Physical, Virtual, and Cloud (RH415) to help prepare. Attendance in these classes is not required; students can choose to take just the exam.

While attending Red Hat classes can be an important part of your preparation, attending class does not guarantee success on the exam. Previous experience, practice, and native aptitude are also important determinants of success.

Many books and other resources on system administration for Red Hat products are available. Red Hat does not endorse any of these materials as preparation guides for exams. Nevertheless, you may find additional reading helpful to deepen your understanding.
