Course Hours
: MW 6 - 7:40 pm
Course URL:
Yuri Cantor
Office Hours:
By appointment

(recommended: networking, some programming, and unix scripting)
Course Description:
The course will introduce the topic of network security through an analysis of attack and defense

techniques. The course will provide students with an understanding of how to identify and exploit

network vulnerabilities and the principles behind securing networks and identifying attacks. Students

will also develop a familiarity with various network penetration testing tools and create a portfolio of

labs demonstrating their proficiency both defending and penetrating networks. Topics will include

scanning, firewalls, intrusion detection, engineering principles, trust, cryptography, and network

Class participation: 5%
Quizes: 20%
Lab Assignments: 50%
Final: 25%
Course Workload:
failure to complete any of the work will result in an INC or an F.
There will

be approximately 5 homeworks. Students will have between 1 and 2 weeks to complete

Each class students will be expected to participate in discussions which may involve all or some of the

following: answering questions about the reading, presenting a problem from the reading, asking

questions about the reading, and presenting or answering questions about the Labs that have been

assigned. Each class will either begin with students writing and submitting an entry slip or end with

students writing and submitting an exit slip.
