However, with the rise of online learning comes the need to address cybersecurity concerns, such as protecting personal data and preventing cyberattacks.

In 2023 there’re over 40 MOOCs providers are offering online courses of 500 universities to 35 million students worldwide, including 2 million in India.

More than 1,200 universities around the world have launched free online courses. In addition to the larger global MOOC platforms (Coursera, edX, FutureLearn), many national governments around the world have launched their own country-specific MOOC platforms, including India, Italy, Israel, Mexico and Thailand.

In 2021, over 220 million students had signed up for at least one course on one of the these platforms, and 40 million did so in 2021 alone (excluding China).

MOOCs and MOOC platforms are still in growing, even after the crazy “Year of the MOOC” prompted by the pandemic and travel restrictions. At Class Central, they try to catalog as many MOOCs as possible, and our listing currently includes more than 150,000 of them, from MOOC platforms and other online learning platforms [1].

The acronym MOOC was coined in 2008 by Dave Cormier of the University of Prince Edward Island, Canada for an online course offered by the University of Manitoba. The Connectivism and Connective Knowledge course designed by Manitoba professors George Siemens and Stephen Downes was free and open to the public who could access video lectures, readings, and participate in discussion forums online [2].

However, it was not until 2011, when the Massachusetts Institute of Technology, Boston (MIT) launched the world’s largest collection of free-of-charge open courseware, that MOOCs captured the attention of academics and educators worldwide. Subsequently in 2012, MIT and Harvard founded the edX platform for the promotion of MOOCs. In 2012, another MOOCs experiment caught academics’ attention. Two Stanford University professors, Sebastian Thrun and Peter Norvig, uploaded a free online course ‘Introduction to artificial intelligence’ for which 160,000 students from 190 countries signed up — the first time, an open online course became truly ‘massive’ [3]. This successful experiment encouraged Prof. Thrun to find the first for-profit MOOCs provider Udacity. This was followed by the founding of Coursera by Stanford professors Dr. Daphne Koller and Dr. Andre Ng.

In 2015, MOOCs continue to grow in size and scale, they will become increasingly attractive targets for cybercriminals. As such, the need for robust cybersecurity measures will only increase.

One of the key challenges in securing MOOC platforms is the large number of users and the diversity of their devices and networks. As cybersecurity expert Dr. Edward Amoroso notes, “The sheer scale of MOOCs presents unique challenges for cybersecurity, as the number of users and devices involved in accessing the platform is much larger than in traditional classroom settings.”

To address these challenges, MOOC providers have implemented various cybersecurity measures, such as encryption of user data, two-factor authentication, and regular security audits [4].

In conclusion, while MOOCs offer many benefits in terms of accessibility and convenience, they also pose unique cybersecurity challenges. It is essential for MOOC providers and institutions to prioritize cybersecurity and implement robust measures to protect their users’ data and prevent cyberattacks.
