tailieunhanh - Lecture Network security: Chapter 1 - Dr. Munam Ali Shah

This chapter provides knowledge of network security. In this chapter students will be able to: provide a survey and exposure of both principles and practice of network security; determine threats to a network and how to protect organization’s systems and data from attacks. This chapter will also help you understand and learn counter measures used to prevent, detect and correct security violations in a computer network. | Network Security CSC332 Dr. Munam Ali Shah PhD: University of Bedfordshire MS: University of Surrey : University of Peshawar Serving COMSATS since July 2004 Some Pictures Park Square Campus, UoB, Luton Putteridge Burry Campus, UoB, Luton New Post Graduate Center, UoB, Luton About the course To provide a survey and exposure of both principles and practice of network security.
