Offensive cyber security operations training

Mastering breach and adversarial attack simulation engagements to validate cyber defenses

DEF CON Training - Bahrain

3-4 November 2025


What you will learn

The hands-on training has been created to provide the participants with a better understanding of offensive security operations, breach and adversary simulation engagements. The goal is to enable the participants to simulate adversaries based on the industry in which their organization operates covering both known and unknown threat actors.
Participants will learn to emulate various threat actors safely in a controlled, enterprise-level environment. In addition to understanding offensive tradecraft and TTPs, participants will gain critical insight into how adversaries operate, which directly supports the ability to test, validate, and improve their own organization's cyber defenses.
Performing such attack simulation engagements not only sharpens offensive skills but also enables defenders to proactively identify gaps, assess detection capabilities, and build more resilient security postures.

This training is designed to benefit both offensive and defensive security professionals. Offensive practitioners will enhance their red teaming and simulation planning expertise, while defensive professionals such as SOC analysts, detection engineers, and blue teamers will gain visibility into attacker behaviors, understand real-world evasion techniques, and learn how to harden their environments more effectively.

Learn advanced breach and attack simulation to validate cyber defenses

The participants will learn to build and simulate various threat-actor and attack profiles safely in a controlled, enterprise level environment. The training would help the participants to simulate known and unknown adversaries by choosing a wide variety of offensive tradecraft, TTPs and planning attack simulation engagements effectively.
