Online education is known for its flexibility, but studies have identified several additional benefits of attending class online. Among them: Personalized learning, Accessibility, Efficiency, Engagement and Cost

Online education may seem relatively new, but years of research suggests it can be just as effective as traditional coursework, and often more so. According to a U.S. Department of Education analysis of more than 1,000 learning studies, online students tend to outperform classroom-based students across most disciplines and demographics. Another major review published the same year found that online students had the advantage 70 percent of the time, a gap authors projected would only widen as programs and technologies evolve.

Online learning platforms are typically designed to be as user-friendly as possible: intuitive controls, clear instructions, and tutorials guide students through new tasks. However, students still need basic computer skills to access and navigate these programs. These skills include: using a keyboard and a mouse; running computer programs; using the Internet; sending and receiving email; using word processing programs; and using forums and other collaborative tools.

An ethical hacker (also known as a white-hat hacker) is the ultimate security professional. Ethical hackers know how to find and exploit vulnerabilities and weaknesses in various systems—just like a malicious hacker (or a black hat hacker). In fact, they both use the same skills; however, an ethical hacker uses those skills in a legitimate, lawful manner to try to find vulnerabilities and fix them before the bad guys can get there and try to break in. An ethical hacker’s role is similar to that of a penetration tester, but it involves broader duties. They break into systems legally and ethically. This is the primary difference between ethical hackers and real hackers—the legality. According to the EC-Council, the ethical hacking definition is “an individual who is usually employed with an organization and who can be trusted to undertake an attempt to penetrate networks and/or computer systems using the same methods and techniques as a malicious hacker.” The role of an ethical hacker is important since the bad guys will always be there, trying to find cracks, backdoors, and other secret ways to access data they shouldn’t. In fact, there’s even a professional certification for ethical hackers: the Certified Ethical Hacker (CEH).

The International Council of Electronic Commerce Consultants (EC-Council) is a professional organization that certifies individuals in various e-business and information security skills. The EC-Council is headquartered in Albuquerque, New Mexico. EC-Council is best known for its professional certifications for the IT security field. It's certifications CEH,CHFI,CCISO,CND are ANSI accredited. It offers certifications in some fields related to IT security, including disaster recovery, software security, digital forensics, and general IT security knowledge.
