The security of computer networks is a key element in cyber security. Computer networking provides the foundational connectivity services that are used for the world wide web, distributed computer applications and services, operations and manufacturing, and national infrastructure.

This course provides understanding of key technologies used in computer networks and infrastructure. This includes protocols, computer networks, data centres, operational technologies that form key infrastructure critical to the success of organisations and services from a local to an international scale. The course discusses vulnerabilities and the exploits that target computer networks, systems, and the Internet infrastructure. By the end of this course learners will be able to: 1. Show a systematic understanding of digital networks and their operation, including the OSI 7 layer architecture and the TCP/IP protocol stack. 2. Discuss key security threats and risks faced in computer networks. 3. Demonstrate a critical understanding of network security architecture and design rationale of selected protocols, security technologies and how they are used in practice. 4. Identify attack models and analyse vulnerabilities in protocols, network systems, and applications. 5. Demonstrate how these vulnerabilities may be exploited in practice to penetrate a system.

In this course you will look at some of the key components of practical cyber security management and its governance. This includes what happens when things go wrong, understanding how organisations can respond to incidents, through to the essential role of people in achieving better cyber security outcomes. Together, you will examine how incident management, cyber resilience, and developing an effective appreciation of people, not simply as users but as active participants, can enable better cyber security outcomes.

The topics covered include: 鈥� Identifying what an incident is 鈥� Incident preparation, planning, and response 鈥� Cyber resilience 鈥� The role of people in security management 鈥� The building of trust and developing positive cyber security cultures By completing this course, you will learn how to integrate incident management and a rich knowledge of people into a real-world Information Security Management System for an organisation.

This course introduces fundamental notions of cybercrime. Namely, what cybercrime is, the main questions surrounding cybercrime, how cybercrime can be defined, and how it can be studied.

You will learn about the difficulties in measuring the occurrence, the frequency and the impact of cybercrime, and build a scepticism on the reliability and the interpretation of cybercrime reports. You will be introduced to discussion about human aspects of cybercrime, in particular, the actors related to cybercrime, that is, the criminals, the victims, and law enforcement. You will also learn about aspects such as personality, national and organisational culture, security culture, training, and other components which affect cybercriminal activity. Finally, you will dive into what is arguably the most important attack vector in cybercrime, that is, social engineering. You will gain an understanding of how it occurs, which techniques social engineers utilise, and which are the underlying psychological principles which make all of us 鈥� as humans 鈥� susceptible to social engineering attacks. By the end of the course you should be able to: 鈥� Reflect on the main questions related to cybercrime. 鈥� Explain the meaning, definitions, importance, and impact of cybercrime. 鈥� Assess the reliability and the interpretation of reports and surveys related to cybercrime. 鈥� Identify the various classifications of cybercrime, the related threats, and threat actors. 鈥� Explain the key role of human aspects in cybercrime. 鈥� Differentiate between the various actors involved in cybercrime and their associated perspectives. 鈥� Evaluate the underlying psychological principles which make social engineering the most successful attack vector in cybercrime. 鈥� Describe how deception and social engineering manifest and how they can be defended against.
