This course will emphasize basic security concepts (authentication, confidentiality, accounting and integrity), apply these concepts to computer networks, and amplify the theory with hands-on aspects of configuring and using secure networks. Topics include: review of networking concepts, general security concepts, user authentication and authorization, encryption, network attacks (including hacking, viruses, worms and denial of service) and network protection. Defense tools including firewalls, Virtual Private Networks (VPNs), and filters will be discussed in depth, as they relate to effective and safe e-commerce and other applications in the real world. Case studies along with projects will be assigned and performed.

This course is designed to familiarize students with basic computer architecture and operating systems and the relationships between hardware and operating systems will be explored. A student who successfully completes this course will also be able to gain strong foundation in the core fundamentals of digital technology. Basic concepts are reinforced by exercises, and hand-on applications. Students will also program and run simple macros in Linux shell. Employability skills, such as Problem solving, Teamwork, Communications and Critical Thinking are integrated into the course work.
