Description
This course focuses on Security and Quality of Service (QoS) in Internet network from technology, regulation and business aspects. It covers Internet fundamentals, including Internet protocols and architectures, Internet security standards and approaches as defined by IETF (Internet Engineering Task Force), as well as ITU's security architectures for end-to-end communications. Further, the course incorporates cybersecurity approaches from the ITU viewpoint, and security aspects of emerging cloud computing and Internet of Things (IoT). Further, the course covers Internet QoS, including the standardized solutions and practical approaches for provision of end-to-end QoS. In that manner, it includes QoS parameters as defined by the ITU and QoS for data (i.e., Over-The-Top services) and mobile services. Finally, the course also covers network neutrality, Internet KPIs (Key Performance Indicators) and their measurements.
This course is targeted at managers, engineers and employees from regulators, government organizations, telecommunication companies and academia, who are interested in understanding, implementation and regulation of Security and QoS in Internet Network, including technologies, standardization, regulation and content. Other institutions and individuals that are dedicated in building their capacity related to Security and QoS in Internet Network are also welcome to participate.
No prior knowledge or qualification is required to register for this course, considering the given target population.
At the end of the training, the participant should have gained an understanding of the key aspects of:
- Internet fundamentals
- Internet security by IETF
- ITU’s security architectures providing end-to-end communications
- Cybersecurity
- Cloud coumputing and Internet of Things (IoT) security
- Internet QoS
- QoS parameters
- QoS for data and mobile broadband services
- Network neutrality and Internet KPIs measurements
- ITU guidelines for QoS regulation
This course will be delivered using instructor-led online learning. The course methodology will be as follows:
- Each day from 16 to 23 June 2025 there will be made available two recorded video lectures. In total, there are 10 video lectures during the course.
- Course forum, asynchronous, will be organized based on discussion topics raised by the instructor on a daily basis, from Course Day 1 to Course Day 5, which will cover the course material on the given day. Also, participant responses will be asynchronous, keeping in mind the different time zones and daily commitments of participants from different countries around the world.
- General discussion forum, asynchronous, will be provided for participants to ask their own questions which can be answered by the instructor and other participants.
- Final Quiz test will be assigned on the last day of the course, 23 June 2025.
- All announcements for all events (lectures, quiz and forum) will be given in a timely manner (prior to the event) by the course tutor.
The evaluation of the participants will be based on 60% from the Final Quiz and 40% from the answers given in the course forum on the raised discussion topics on daily basis by the tutor, thus reflecting both the quantity and the quality of time spent on the course.
Participation in the course forum is mandatory in order to access the Final Quiz.
The Final Quiz will be open from 00:00 hours on Monday (23 June 2025) according to the GMT+1 time, and will remain open for 30 hours after opening, so each participant can choose the most convenient time to solve it. However, after the start of the attempt the Quiz should be completed in 90 minutes. The Final Quiz contributes with 60% in the total grade.
The course is completed successfully with a total grade of 70% or higher. The grading will be completed by the course tutor after the course is fully completed.
Each fully registered participant who successfully completes the course with a total grade of 70% or higher will receive an ITU Certificate for this course.
The ITU certificates will be given to participants via the ITU Academy platform after completion of the course reporting and processing within the ITU.
