Share Description
This course covers the fundamentals of cyber defence, beginning with foundational models like the Bell-LaPadula and information flow frameworks. These underlying policy enforcement mechanisms aid in the introduction of basic functional safeguards, beginning with authentication methods. In the context of a canonical schema, students will be introduced to a variety of authentication solutions and protocols, including RSA SecureID and Kerberos.
