This page is dedicated to sharing errors identified in the CompTIA Security+: Get Certified Get Ahead: SY0-301 Study Guide. If you know of any errors in the book, please let me know.

While not an error, you should know that CompTIA has added performance based type questions to the exam. The objectives are the same, but the format of the questions are different. This page has links to multiple blogs including blogs on the new performance based questions.

A. Backups
B. Security audit
C. Security guard
D. Periodic review of user rights
Page 128 Change the description to:4. C. A security guard (armed or not armed) is a preventative physical security control. A backup is a corrective control. A security audit is a detective control and a
periodic review of user rights is a specific type of detective control.Note: While it’s true to say that the principle of least privilege is a technical control, this refers to the type of control (technical, management, and operational). However, it’s function is also as a preventative control. Common functional controls are preventative, detective, and corrective. All other answer descriptions focused on the function but the answer description for least privilege focused on the type.With the original question, it is accurate to say that both least privilege and security guards are preventive controls. However, the question implied only one answer was correct.
