The course will cover a wide range of topics in network security and online privacy, trying to strike a balance between core concepts and recent advancements. Although clearly distinguishing between “systems” and “network” security is challenging, our focus will be on technologies, protocols, attacks, and defenses most closely related to the network rather than the endpoints.

The main goal of the course is to provide an understanding of various network security concepts through a more adversarial way of thinking. By focusing on vulnerabilities and exploitation techniques, the course will cover a broad range of topics, including core network protocols, eavesdropping, scanning, DoS attacks, firewalls, VPNs, proxies, intrusion detection, forensics, honeypots, encrypted communication, authentication, services and applications, botnets, targeted attacks, exfiltration, privacy, anonymity.

All topics will be covered from a highly practical perspective, following a mixed format of lectures, hands-on sessions, research paper discussions, and case studies. Other requirements include four programming assignments and two exams.

Credits: 3

University Policies

Students are expected to attend every class, report for examinations, and submit major graded coursework as scheduled. In the instance of missed lectures or labs, students are responsible for reviewing posted slides and supporting material. Students will be provided reasonable accommodations for missed exams, assignments, or projects due to significant illness, tragedy, or other personal emergencies, on a case-by-case basis. Students unable to report for any exams or complete major graded coursework as scheduled must contact the instructor as soon as possible. Make-up exams may be given only in extenuating circumstances, and only by providing a doctor's note stating that the student was ill and unfit to take the exam.

Student Accessibility Support Center

If you have a physical, psychological, medical, or learning disability that may impact your course work, please contact the Student Accessibility Support Center, Stony Brook Union Suite 107, (631) 632-6748, or at sasc@stonybrook.edu. They will determine with you what accommodations are necessary and appropriate. All information and documentation is confidential.

Academic Integrity

Students must pursue their academic goals honestly and be personally accountable for all submitted work. Representing another person's work as your own is always wrong. Please read carefully the Computer Science Department's Policies and Procedures Governing Graduate Academic Dishonesty. Faculty is required to report any suspected instances of academic dishonesty to the Academic Judiciary. Faculty in the Health Sciences Center (School of Health Professions, Nursing, Social Welfare, Dental Medicine) and School of Medicine are required to follow their school-specific procedures. For more comprehensive information on academic integrity, including categories of academic dishonesty please refer to the academic judiciary website.

Critical Incident Management

Stony Brook University expects students to respect the rights, privileges, and property of other people. Faculty are required to report to the Office of Judicial Affairs any disruptive behavior that interrupts their ability to teach, compromises the safety of the learning environment, or inhibits students' ability to learn. Faculty in the HSC Schools and the School of Medicine are required to follow their school-specific procedures.
