Having the correct time helps to ensure systems operate properly, especially if you have configured things like time-based access. In this course, you'll explore the Network Time Protocol, including attributes and enumeration tools. You'll also examine the Network File System and how it can be taken advantage of when implemented incorrectly. Finally, you'll learn about the Simple Mail Transfer Protocol (SMTP) and File Transfer Protocol (FTP), including what details can be enumerated from target systems using both of these protocols. This course is one in a series that helps to prepare you for the Certified Ethical Hacker v11 (312-50) exam.
