This is quite a notable addition to the list of free training sources. The United States is a preferred target for cyberattacks and most of its citizens are not aware of the basics of cybersecurity. The website offers free training to all who are eager to learn more about cybercrime and cybersecurity. Since many attacks against US companies have been industrial espionage, the courses provided on the department's training website are focused on industrial environments. The course is designed for beginners in cybersecurity but experts can take it to specialize in preventing threats against industrial systems. The trainees are given certification upon the successful completion of a course.
There are many other websites that offer cybersecurity training. However, many of the free academies do not offer quality teaching materials and do not give certifications. Three of the sites listed here do offer certifications and all of them have quality information. Therefore, they are invaluable sources of cybersecurity intelligence.
