Infrastructure security training

Strengthen the security of your Windows, Linux and Active Directory environments. Through a modular programme combining theory, demonstrations and hands-on exercises, learn to harden your systems, reduce their attack surface and improve the detection of security events.

ARC-210 · Intermediate · 2 to 6 days · 10 participants max. · Demos + workshops

Why train in infrastructure security?

A poorly configured or under-monitored infrastructure can quickly become an entry point, a path for an attack to spread or a blind spot for security teams. Administrators must therefore be able to harden systems, protect critical services and detect abnormal activity earlier.

This course gives a structured view of the main risks affecting Windows, Linux and Active Directory environments. You will learn to apply concrete hardening measures, limit the attack surface and strengthen the operational resilience of your infrastructure.

The programme is organised in four independent modules covering Windows hardening, Linux hardening, Active Directory security, and monitoring and logging. They can be taken separately or combined into a coherent path suited to your environment and your teams' priorities.

What you will be able to put into practice

By the end of the course, you will be able to:

  • Assess

    the main risks of an infrastructure, understanding the technical responsibilities that come with administering and securing systems.

  • Identify

    the common weaknesses of Windows, Linux and Active Directory environments to prioritise the most relevant protection measures.

  • Implement

    effective hardening measures to reduce the attack surface, strengthen monitoring and improve the infrastructure's resilience.

  • Apply

    the concepts in dedicated environments through demonstrations, hands-on exercises and configurations you can carry straight into operations.
