Computer Networks 1: Lecture 13 - Network Security provides about Security in Brief, Most Common Perpetrators, Cryptography (Symmetric-key algorithms, Public-key algorithms, Digital Signatures, Management of Public Keys); Apply to Computer Networks. | HCM City University of Technology Department of Computer Science and Engineering Chapter 13 Network Security Reference Chapter 8 - Computer Networks Andrew S. Tanenbaum 4th Edition Prentice Hall 2003. Advanced Principal Concepts Samples and Techniques Foundation Summary Q Question and Answer o Introduction Network security is looming on the horizon as a potentially massive problem Studying network security from several angles Pointing out numerous pitfalls Discussing many algorithms and protocols for making networks more secure Most security problems are intentionally caused by malicious people trying to gain some benefit get attention or to harm ___________ 2 someone Security in Brief It is concerned with. Making sure that nosy people cannot read or secretly modify messages intended for other recipients People trying to access remote services that they are not authorized to use The problems of legitimate messages being captured and replayed People trying to deny that they sent certain messages Four intertwined areas secrecy authentication nonrepudiation and integrity control
