Agenda: CCS Session 1 –
Ethernet Basics
Date: Tuesday, February 28, 2023
Time: 08:00 am to 12:00 pm CET
Goal
In this course you will receive an introduction to basic Ethernet communication as well as an overview of the most important application protocols.
- The participants get to know the general idea of Ethernet
- Understand the role of Layer 1-4 and the applications
- Some hints about analysis of Ethernet frames and the data from the point of view of higher layers
- get a good basis for other Combined Charging System trainings
Prerequisites
Knowledge of serial communication is advantageous but not required
Agenda
1. Ethernet Fundamentals, OSI Layers 1 to 4
- Physical Layers (very short)
- Ethernet basics
- IP basics
- Axilliary Protocols (ARP, NDP, ICMP, DHCP...)
- Introduction to TCP and UDP
2. Overview Application Protocols e.g.
Work status - subject to change without notice. Time Zone: CET.
Agenda: CCS Session 2 –
Security Basics
Date: Thursday, March 02, 2023
Time: 08:00 am to 12:00 pm CET
Goal
In this course you will start with an overview of commonly used security mechanisms and their usage in various security protocols.
A more detailed introduction of the TLS protocol, sequences and phases follows.
The course will be completed by a short look into a live TLS demonstration.
Four main points are the intention of this course and the reason why it may be booked:
- make the complex subject easy to understand
- get an general understanding as basis for dicussions
- get rid of anxieties caused by its complexity
- get a good basis for other Combined Charging System trainings
Prerequisites
Overview of communication protocols (OSI layers 1-4) and applications.
Agenda
1. Introduction
- General goals of Security
- Cyber Security within the OSI Layers
- Overview of Security tasks, methods, algorithms and protocols
2. Basics of Security
- Symmetrical and asymmetrical Cryptography
- Hashing , Message Authentication Code and signatures
- Certificates, Key Exchange and Cipher Suite
3. Transport Layer Security (TLS) and Datagram TSL (DTLS)
- TLS/DTLS Phases and sub-protocols
- Authentication by certificates
4. Other Security Protocols
Work status - subject to change without notice. Time Zone: CET.
