CNT 4403 - Computing and Network Security
Undergraduate course, FIU, 2025
Fundamental concepts and principles of computing and network security, symmetric and asymmetric cryptography, hash functions, authentication, firewalls and intrusion detection, and operational issues. Prerequisites: CGS3767 Corequisite: CGS4285. Enrollment Requirements: Please Note: Fully Online Program students may not enroll in this class section. Prerequisites: CGS3767 Corequisite: CGS4285.
CIS 5374 - Security and Privacy: Attacks and Defenses
Graduate course, FIU, 2026
The course examines a broad range of cyber threats, including common attack types, threat models, and adversarial techniques, alongside defensive strategies and security mechanisms used to mitigate these risks. In parallel, the course explores key privacy issues in computing and information systems, including fair information practices, the tension between anonymity and privacy, privacy risks, tracking and surveillance technologies, and the tools, policies, and regulatory frameworks designed to protect personal data. Students will develop the ability to analyze security and privacy problems critically, evaluate technical and policy-based solutions, and reason about trade-offs between usability, security, and privacy in real-world systems. Prerequisite: M.S. or Ph.D. standing, or permission of the instructor.
