CENG 418
Information Security
Information Security is a comprehensive study of the principles and practices of computer system security including operating system security, network security, software security and web security. Topics include common attacking techniques such as virus, trojan, worms and memory exploits; the formalisms of information security such as the access control and information flow theory; the common security policies such as BLP and Biba model; the basic cryptography, RSA, cryptographic hash function, and password system; network intrusion detection; software security theory; web security; legal and ethical issues in computer security.
Learning Outcomes:
1.To be able to learn the common security threats in digital world.
2.To be able to learn the foundational theories of information security.
3.To be able to learn what are the basic principles and techniques when designing a secure system.
