This report, prepared for Southern Cross University, addresses critical cybersecurity concerns. It begins by evaluating the current password-based authentication system and the risks introduced by the Bring Your Own Device (BYOD) policy, including malware, untrusted operating systems, and network vulnerabilities. The report then explores the advantages of certificate-based authentication as a more secure alternative. It analyzes the threats posed by spamming attacks and provides recommendations for implementing anti-spam guidelines. The report also assesses the risks associated with BYOD, such as malicious software installation, the use of untrusted operating systems and applications, and the exploitation of untrusted networks. The report emphasizes the importance of digital certificates in verifying user identities and securing data transmissions. It highlights the benefits of certificate-based authentication, including its user-friendliness, excellent access control, and mutual authentication capabilities. Finally, the report emphasizes how the implementation of certificate-based authentication will help the university protect its data and restrict unauthorized access to sensitive information.
