Ethical Hacker & Cyber Defence

Ilaria Digital School

Become a cybersecurity specialist, from scratch to professional penetration testing: understand systems and networks, attack ethically within an authorised scope, defend, investigate and secure development. Skills: Master the mathematical foundations of computing and cryptography; Understand computer and operating system architecture, administer Linux; Design and analyse a network; Program in Python and optimise algorithms; Secure an information system; Design and query a database; Use artificial intelligence in attack and defence; Test the security of web and mobile applications; Carry out a complete penetration test and its report; Conduct a digital forensic investigation; Analyse malware; Develop securely; Integrate security into continuous integration and deployment; Analyse risks and audit an organisation's security. Workshops take place in your isolated lab, on training targets and samples you install yourself; no real system is touched, and the data you need is provided.

    Use traceroute to see jumps

    THEORETICAL RECAP Traceroute (or tracert on Windows) is a network diagnostic tool that maps the path packets take from your machine to a destination host, revealing each intermediate router — called a 'hop' — along the way. It operates at Layer 3 (Ne...

    Layer 3 Network — the role of routers and IP

    INTRODUCTION AND POSITIONING IN THE OSI MODEL You have already explored Layers 1 and 2 of the OSI model. You know that Layer 1 (Physical) handles signals and transmission media, and that Layer 2 (Data Link) manages the framing of data, error detectio...

    Identify errors in a frame

    THEORETICAL RECAP An Ethernet frame is a structured unit of data that operates at Layer 2 (Data Link) of the OSI model. It carries a payload from one MAC address to another within the same network segment. A standard Ethernet frame contains the follo...

    Read a captured Ethernet frame

    THEORETICAL RECAP An Ethernet frame is the fundamental unit of data at Layer 2 (Data Link) of the OSI model. When two devices communicate on a local network, data is broken down into frames before being transmitted over the physical medium. Each Ethe...

    Layer 2 Data link — Ethernet & MAC frame

    Now that you have explored Layer 1, which deals with physical signals, cables, and transmission media, it is time to move up one level in the OSI model. Layer 2, called the Data Link layer, sits directly above the physical layer and adds the first la...

    Choosing the right cable (interactive scenario)

    THEORETICAL RECAP At OSI Layer 1 (Physical), the cable is not just a wire — it is a medium that determines speed, distance, interference resistance, and ultimately, the reliability of your entire network stack. Three main cable families dominate ente...

    Layer 1 Physics — supports and signals

    You have already explored what the OSI model is, how encapsulation works, and what IP addresses and packets look like in practice. You even observed real network traffic with tools like ping and Wireshark. Now it is time to go deeper into the foundat...

    Stack the diapers (virtual Lego activity)

    **Theoretical Recap** The OSI model (Open Systems Interconnection) is a conceptual framework that standardizes network communication into 7 distinct layers: Physical (1), Data Link (2), Network (3), Transport (4), Session (5), Presentation (6), and A...

    Introduction to the OSI model and encapsulation

    In the previous activities, you explored the basic vocabulary of networks, learned to identify IP addresses, observed packets with the ping command, and distinguished between switches and routers. You now have a solid mental picture of what a network...

    Visualize a network flow with an online simulator

    **Theoretical Recap** Before diving into the simulator, let's consolidate what you've covered so far. A network is a set of interconnected devices (hosts) that exchange data through links in the form of packets. Each packet carries a source and desti...

    Topology concept, switch vs router

    Before diving into the differences between a switch and a router, it is essential to understand what a network topology is and why it matters for anyone working in cybersecurity or DevSecOps. A network topology describes the physical or logical arran...

    Associate IP addresses with equipment

    **Theoretical Recap** An IP address (Internet Protocol address) is a unique numerical identifier assigned to every device connected to a network. IPv4 addresses are written in dotted-decimal notation (e.g., 192.168.1.1), composed of four octets rangi...

    Observe an ICMP packet with ping

    **Theoretical Recap** ICMP (Internet Control Message Protocol) is a network-layer protocol (OSI Layer 3) used primarily for diagnostic and error-reporting purposes. Unlike TCP or UDP, ICMP does not carry application data — it carries control messages...

    IP address and packet concepts

    Now that you are familiar with the basic vocabulary of networks — hosts, links, and packets — it is time to go deeper into two fundamental concepts that underpin virtually every communication on the internet and on private networks: the Internet Prot...

    Map your home network

    **Theoretical Recap** Before diving into the workshop, let's consolidate the core concepts you've encountered so far. A network is made up of hosts (any device with an IP address: computer, smartphone, printer, router, smart TV), links (the physical ...

    Basic vocabulary of a network (host, link, packet)

    Understanding how networks work is the foundation of cybersecurity. Before diving into attack techniques, penetration testing tools, or secure deployment pipelines, you need to be fluent in the basic vocabulary that describes what a network is and ho...
