E-learning system is a web-based system which is exposed to computer threats. Services or asset of the e-learning system must be protected from any computer threats to ensure the users have peace of mind when using it. It is important to identify and understand the threats to the system in order develop a secure system. The main objectives of this paper are to discuss the computer security threats towards the e-learning system assets and to study the six categories of computer security threats to the e-learning assets. The activities which involve the e-learning assets will be analyzed and evaluated using the STRIDE model. The results show that the e-learning system assets are exposed to threats on availability, integrity and confidentiality .Our findings also show that the high risk assets are assessment and students’ assessment marks.
