Course Description:	Techniques for achieving security in multi-user computer systems and distributed computer systems: Basics of cryptography, network security applications and system security, conventional encryption and message confidentiality, public-key cryptography and message authentication, authentication applications. Electronic mail, IP, web.
Course Objectives:	To present a survey on network security technology. It covers important network security tools and applications, including the major cryptographic algorithms and techniques, security protocols, digital signatures, message and user authentication techniques, cloud security, network access control, personal identity verification (PIV), mobile device security, S/MIME, IP Security, Kerberos, SSL/TLS, and X509v3. In addition, methods for countering hackers and viruses will be explored. Finally, fundamental security design principles, attack surfaces and attack trees, practical application of RSA, user authentication models and comprehensive email security will be discussed.

BASIC CONCEPTS OF THE COURSE

1	The OSI Security Architecture is the basis of this introductory on Network Security Essentials.
2	Stream Ciphers will be used to explain the concept of both symmetric and asymmetric encryption.
3	Establishing the identity of the sender will be explored by studying authentication algorithms.
4	Ensuring confidentiality is essential and the concepts to ensure this will be explained covering secure key distribution.
5	The use of Cloud Computing is ubiquitious and pervasive. Concepts dealing with securing network access and the cloud will be covered.
6	Web Security is paramount and the issues and solutions to address this will be covered.
7	Securing the air interface will be explored at a system level using WiFi access to explain wireless network security.
8	The various strategies used in electronic mail security will be explored covering PGP and DNSSEC.
9	Security at the various layers such as the IP and Network layer will be studied covering the basic concepts.
10	Finally legal and ethical issues will be explored.
