Network Security

Explore, Exploit, Secure

Network security is not a single control — it is a discipline. This five-day programme takes participants from advanced networking foundations through to hands-on domain exploitation and cryptographic defence, giving them the knowledge to both uncover and close the gaps that attackers exploit.

The course is structured around five chapters that mirror how a real network intrusion unfolds: reconnaissance, authentication abuse, scripted enumeration, exploitation, and the cryptographic layer underneath it all. Every chapter closes with attack scenario familiarisation so theory is immediately anchored in practice.

What your team will learn

By the end of the programme, participants will be able to:

• Apply network security principles and interpret traffic using tools such as Wireshark, tcpdump, and Responder
• Configure and secure Active Directory environments, including Kerberos and LDAP domain services
• Use PowerShell for Windows administration, log analysis, and enumeration tasks
• Identify and exploit domain vulnerabilities using Msfconsole, Impacket, CrackMapExec, and Mimikatz
• Understand and apply classic and modern cryptographic methods to protect data in transit and at rest
• Map common attack patterns — Pass-The-Hash, Golden Tickets, LLMNR poisoning — to concrete defensive controls

Who it is for

This programme is suited to network engineers, system administrators, security analysts, and IT staff responsible for protecting Windows-based infrastructure. It is particularly valuable for teams that want to understand how attackers move through a network so their defences and monitoring are purposeful, not reactive.

How you will learn

Training is delivered on-site using an apprenticeship-based approach that prioritises demonstration over lecture slides.

Hands-on labs throughout. Every chapter is built around virtual and host machine exercises. Participants work directly with the tools and techniques covered rather than watching slide decks.

Trainer-led demonstration. The trainer works through each attack scenario live, bridging theory to practice in real time. Participants then replicate and extend what they have seen.

Repeated practice and challenge questions. Each topic includes practice questions that reinforce understanding, and challenge questions that develop critical thinking by connecting techniques across chapters.

Attack scenario familiarisation. Every chapter closes with a realistic scenario that ties together the skills covered, preparing participants to navigate a corporate network compromise from both the attacker and defender perspective.

Class size: Up to 30 participants per trainer (1:30 ratio). Sessions are scheduled to suit your organisation’s requirements.

Entry requirements

This is an intermediate-level programme. Participants should have:

• Basic familiarity with TCP/IP networking concepts
• Some exposure to Windows environments and the command line
• No prior cybersecurity certifications are required, but a willingness to engage with hands-on technical exercises is essential
