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 5

Network security Security goals: Data confidentiality, data integrity and authentication Access control for network

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 (Do. S) 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. 6

Goals Know common communications systems, classic security mechanisms, and some of the latest ideas

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 7
