Syllabus
Chapter 1: Introduction
This chapter motivates the security problem and introduces terms associated with the security arena,
specifically the CIA (Confidentiality, Intergrity and Availability) triad.
Chapter 2: Modern Cryptography
This chapter contrasts classical vs modern crytography and then delves into the modern cryptography building
blocks that provide confidentiality and integrity, namely symmetric key cryptography, asymmetric key cryptography,
hashes, message authentication codes and digital signatures.
Chapter 3: Cryptographic Protocols
This chapter delves into challenges that arise when using the above building blocks in real-life via
cryptographic protocols. Specifically, it will cover key distribution, human authentication and protocols
that provide one-way, two-way and mediated authentication. The cryptographic protocol SSL/TLS will also be
covered as a case study.
Chapter 4: Network Security
The Internet has not been designed with security in mind. This chapter introduces various attacks possible
at the various layers of the Internet protocol stack (ARP spoofing, Smurf attack, TCP session hijacking, DNS
Pharming etc) and solutions to the same. It will also cover some of the latest secure networking protocols
(SSH, IPSec, WEP, WPA, etc).
Chapter 5: Web Security
This chapter focuses exclusively on web-based attacks, both client-side (Phishing, XSS, XSRF etc) as well as
server-side (RFI, LFI, SQL injection, etc) and solutions to the same.
Chapter 6: Lab Material
This chapter contains lab exercises and material that explore many of the above-covered concepts via
“Openssl” commands and other frameworks (e.g. Scapy).
