Overview
• Today’s Topics
• What is network security and how does it fit
within EWU curriculum?
• Network Security fits within the broader
topic of general security
• Some expectations
• Learning Objectives for this course
• Pre-test of network security
Network Security Defined
• Network Security
– How would you define it?
– Protection of networks and their services from
unauthorized modification, destruction, or
disclosure
– Study of both attack and defense techniques
that affect the network
Our Curriculum
• CSCD 330 – Network programming
– Basic networking course with an emphasis on
programming
• CSCD 433/533 – Advanced Networking
– More depth, cover network principles, design
– Cover other protocols, real-time, QOS
– Some programming
Our Curriculum
• CSCD 434 Network Security
– Computer networks focus of both threats and
defense.
– Begin with coverage of Attacks and Attackers
• What they typically do to gain access to
computers on a network
• Examine different phases of an attack
• Learn tools and techniques attackers use
– Try some out in the lab
• Try to answer, Why attack?
Our Curriculum
• CSCD434 continued …
– Talk about Defense Mechanisms against
attackers
• Detection/Prevention – Network security policies
• Authentication, users and machines
• Firewalls and Intrusion Detection
• Use of Cryptography as network defense
– Whats its real value?
– Where it works and where it doesn’t work
General Computer Security
• How do you define computer security?
– Application of hardware, firmware and
software security
• To a computer system in order to protect
against, or prevent,
• Unauthorized disclosure,
• Manipulation, and deletion of information or
• Denial of service
General Computer Security
• Where does network security fit within a security
curriculum?
– Introductory Security class, CSCD303
• Basics of computer security, code and
hardware vulnerabilities, OS protection
mechanisms, cryptography based protection,
authentication
– Cryptography
• Algorithms and math that define cryptography
General Computer Security
• CSCD496 - Computer or Digital Forensics
• Capture data related to proof of electronic
crimes
• Recoverability of data from both host and
network
• CSCD437 - Secure Coding taught by Tom Capul
• Learn how to avoid software vulnerabilities
• Attacks that can take advantage of code
vulnerabilities and how to create more secure
programs
Network and General Security

General Security
Pre-requisite Knowledge
• Pre-requisites
– Network course
• Should know basic TCP/IP networks
– Knowledge of programming such as C, C++,
C# or Java, Python or Pearl
• We will review some networking concepts
– Point you to some supplemental material on
TCP/IP Networks to fill in the gaps
Student Learning Objectives
• By end of this course you should
– Understand threats to computer systems
through network
– Understand and be able to set up defense
mechanisms used to counteract threats
– Understand role of cryptography in network
defense
– Know how to continue learning about network
security beyond this class
• Certifications, Journals, Web Sites
Expectations for You
• Come to Class
– Listen, learn and ask lots of questions
• Download lecture notes
• Do reading if assigned
– There will be outside reading!!!!
• Want in-class participation
• There will be group exercises in class
• Labs
Expectations for You
• Produce a project
• Programming or experiment
• Short write up of results
• Presentation of your results
Or
• Create a research paper
• Survey paper
• And do a presentation of a topic
Project or Program
• This will be a substantial part of your grade
• And, you can become a group too
– Groups need to outline who is doing which job
– Work should reflect greater effort from a group
Conclusion
• Interesting class, increase everyone’s
knowledge of network security
• Topic is challenging
• Broad and changes constantly
• Nothing really difficult, but is a large topic
• Naturally interdisciplinary
– Extends beyond the technical
• Social and people-related issues
• Policy and laws
• We will cover some of this
The End
• This week no Lab
• Next Time
