Presentation Transcript

  1. Network Security — Welcome and introduction Network security at TKK, Nov-Dec 2009 Tuomas Aura

  2. My background • Lecturer: Tuomas Aura, tuomas.aura@tkk.fi • PhD from Helsinki University of Technology in 2000 • Microsoft Research, UK, 2001–Sep 2009 • Professor at TKK 2008–, full time since 1 Nov 2009 • Research: • Network security • Security protocol engineering • Security of mobility protocols (Mobile IPv6, SEND, etc.) • Privacy of mobile users • DoS resistance

  3. Course arrangements • Tuesdays and Wednesdays 13:15–16:00 T4 • Period II in year autumn 2009 • 10 lectures (6th week in reserve) • Exercises Fridays 14:15-16 T4 • First exercise session on 13 Nov, last on 11 Dec • Mandatory exercises • Course assistants: • JyrySuvilehto • Elena Reshetova • Examination 18 Dec 2009

  4. Recommended reading • Lecture handouts • Preliminary versions on my old Microsoft homepage • Final versions in Noppa after the lectures • William Stallings,Network security essentials: applications and standards, 3rd ed., Pearson Prentice Hall, 2007 • Kaufman, Perlman, and Speciner, Network security: PRIVATE communication in a PUBLIC world, Prentice-Hall, 2002 • Wikipedia, web, RFCs and standards

  5. Exercises • Mandatory exercises • Pass/fail, must pass at least 4 out of 5 rounds • Problems in Noppa by Friday each week • Solutions to be submitted by Thursday midnight before the Friday exercise session • Keep solutions to 2 pages per round • Submission instructions will be in Noppa • Try to solve all problems at least partly • The goal is not to have all right answers; the goal is to learn how to find information • Individual work; do not copy or even look at the written answers of other students; write your own

  6. Network security • Security goals: • Data confidentiality, data integrity and authentication • Access control for network access • Integrity of signalling protocols and routing systems • Denial-of-service (DoS) protection • Software security • Application-level security goals, e.g. non-repudiation • Security is not cryptography • Cryptography is seen as an abstract building block • Protocol design assuming the most common crypto primitives • Network technology • Must know about TCP/IP, 802.11, UMTS etc.

  7. Goals • Know common communications systems, classic security mechanisms, and some of the latest ideas • Understand network security technologies, their properties and limitations to use them right • Be aware of the pitfalls in security engineering: security is not just mathematics or just code • Starting point for learning more on the job or in further studies • Learn the adversarial mindset of security engineering
