Security of Internet
In this course , learn about the security risks of the internet of things.
Introduction
The internet security is a term which describes security for transactions and all activities you make online. It is actual factor of computer security and cybersecurity, including browser security, online security and network security.
The following definitions will help during this course:· Hacking – the gaining of unauthorised access to data in a computer system
· Phishing – a form of social engineering attack used to steal personal data by an attacker disguised as a trusted organisation
· Legacy technology – an old technology no longer supported by development
· DDoS – Distributed Denial of Service
· Endpoint – a remote device that communicates with a network it is connected to (such as a desktop or laptop)
· Honeypot – a system intended to mimic likely targets of cyberattacks
You will learn
- Discuss the security risks of the Internet of Things
- Investigate ways of securing the Internet of Things
Internet of Things
In this course , learn about the internet of things and its purpose.
Introduction
These definitions will help during this course:· RFID – Radio Frequency Identification
· IP – Internet Protocol, a set of rules defining the format of data transferred over the internet or network
· Broadband Internet – an internet connection with a high data transfer rate
· Cellular Network – a radio network distributed over cells each served by a base station
· Wireless Network – a network that uses wireless data connections between nodes
The Internet of Things (IoT) is the term applied to everything connected to the internet. It is increasingly being used to define objects that talk to each other. These devices range from sensors to smartphones and wearable technology (e.g. FitBit or Apple Watch).
The IoT enables devices on private networks to communicate with others. This in turn, creates a more connected world across multiple different network types.
You will learn
- Look at the fundamentals of the Internet of Things
- Investigate how the Internet of Things can be enabled for all users
Introduction To 5G Technologies
In this course, introduction to 5G technologies.
Introduction
5G is the fifth generation of mobile/cellular networks. It is a new global wireless standard after 1G, 2G, 3G, and 4G networks and its Uup to 100 times faster than 4G. 5G is creating never-before-seen opportunities for people and businesses. 5G wireless technology delivers higher multi-Gbps peak data speeds, ultra low latency, more reliability, massive network capacity, increased availability, and a more uniform user experience to more users.
In this course we will first look at some definitions associated with radio networks:· Electromagnetic spectrum
· Base stations
· Cells
The electromagnetic spectrumElectromagnetic radiation covers a range of frequencies (spectrum) and associated wavelengths, commonly referred to as the electromagnetic spectrum. Radio waves have lower frequencies and longer wavelengths than visible light.
You will learn
- Introduce 5G technologies
- Explore 5G use cases and their benefit
Fundamentals of Electronic Communication
in this course, learn about the the fundamentals of electronic communication.
Introduction
Sine waves are used in math and physics to represent waves. See below for some key definitions that will be used throughout the session:Frequency (f)
· This is the number of cycles per second measured in hertz (Hz)
· 1 Hz = 1 cycle per second
Amplitude (A)
· The height of a cycle
Phase (Φ)
· The relative value of a variable at a point in a cycle
Wavelength (λ)
· The physical distance over which a cycle repeats
Relationships
The wave speed (c) of electromagnetic (EM) radiation is 300,000 km/s (the ‘speed of light’).So, as the wave speed (c) is constant:
· Lower frequencies always have longer wavelengths
· Higher frequencies always have shorter wavelengths
Wave speed (c), frequency (f) and wavelength (λ) are related and can be represented by a formula triangle.
\( f= \frac{c}{ \lambda } \)
Where: c = wave speed, f = frequency and λ = wavelength
\( c \equiv f \times \lambda \)
Where: c = wave speed, f = frequency and λ = wavelength
\( \lambda \equiv \frac{c}{f} \)
Where: c = wave speed, f = frequency and λ = wavelength
You will learn
- Introduce the basic concept of wave theory
- Explore the electromagnetic spectrum
Digital Transformation
In this course, learn about Industry 4.0 and Digital Transformation.
Intoduction
The digital transformation has become very important, it is now responsible for changing industry and adapting it to a connected industry.
The following definitions will help during this session:· Programmable Logic Controllers (PLC) – an industrial solid-state computer that makes logic-based decisions for automated processes based on monitored inputs and outputs
· Cloud Computing – the delivery of computing services over the Internet
· Artificial Intelligence – the ability of machines or computer systems to learn and adapt similarly to humans
· RDA – Remote Database Access
· RFID – Radio Frequency Identification
You we will learn
· Explore Industry 4.0· Discuss how the Internet of Things (IoT) and 5G enable Industry 4.0
How Surveillance is Used by Different Public Services
Learn more about how individuals and society are defended and protected. This course is ideal for intermediate learners.
Introduction
Surveillance is close observation, especially of a suspected spy or criminal. With technology constantly developing and advancing, the surveillance that is used has to stay current and up-to-date.
It is estimated that there are between 4 and 6 million CCTV cameras in the UK alone (at the time of writing). There are over 600,000 cameras just in London. The government recommends keeping CCTV footage for 28 days, although there is no set legal time for storing images. On an average day, a person is caught on CCTV cameras up to 300 times.
Along with cameras, there are other types of surveillance available in the UK too. For example, a person’s location can be tracked through a mobile phone that is turned on – whether the phone is in use or not.
You will learn
- What is surveillance?
- Why do we need surveillance?
- How is surveillance used?
