Threat-Led Security (TLS) is a proactive, data-driven approach that moves beyond compliance-based testing to simulate the Tactics, Techniques, and Procedures (TTPs) of real-world adversaries targeting the organisation. This course provides an in-depth, hands-on methodology for conducting Red Team operations and Adversary Simulation. Participants will master how to emulate threat actor behavior, assess the effectiveness of defensive controls (Blue Team), and work collaboratively in "Purple Team" exercises to close critical security gaps. The goal is to rigorously test security defenses against the most relevant, current threats, ensuring the security program delivers maximum defensive value.

- Incident Response Team Members.
- Vulnerability Management Specialists.
- Security Architects.
Methodology
- Hands-on labs using Red Team tools to simulate C2, persistence, and lateral movement.
- Group activity developing a threat profile and TTPs for a mock Red Team engagement.
- Mandatory Purple Team exercise collaborating to build a new SIEM detection rule.

Course Outline
Unit 1: Foundations of Threat-Led Security
Section 1.1: The TLS Methodology- Defining Threat-Led Security (TLS) and its distinction from Penetration Testing.
- The role of Red Teaming, Blue Teaming, and Purple Teaming.
- Leveraging the MITRE ATT&CK Framework as the common language for TTPs.
- Establishing clear scope, legal authorization, and rules of engagement (ROE).
- Identifying and prioritizing relevant threat actors (e.g., APTs, Cybercrime).
- Mapping threat actor TTPs to the organisation's assets and controls.
- Developing specific, measurable Red Team objectives based on threat intelligence.
- The importance of "intelligence-driven" over "exploit-driven" testing.
Unit 2: Red Team Operations Lifecycle
Section 2.1: Planning and Reconnaissance- The Red Team Kill Chain and planning phase.
- Deep external and internal reconnaissance (OSINT, network mapping).
- Developing and utilizing custom C2 (Command and Control) infrastructure.
- Creating believable pretexts for social engineering and physical access.
- Techniques for gaining initial access (phishing, public-facing exploits).
- Bypassing perimeter controls (e.g., EDR, AV, NGFW).
- Exploiting identified vulnerabilities to gain a foothold.
- Maintaining persistence without detection.
Unit 3: Internal Movement and Objectives
Section 3.1: Privilege Escalation and Lateral Movement- Post-exploitation techniques for privilege escalation (e.g., misconfigurations, kernel exploits).
- Lateral movement techniques (Pass-the-Hash, RDP, WMI).
- Credential dumping and harvesting strategies.
- Avoiding detection by internal network security controls.
- Identifying and exfiltrating "Crown Jewel" data assets.
- Simulating disruption and denial-of-service against critical systems.
- Testing the organisation's readiness to respond to a major incident.
- Documenting all TTPs used and their success/failure against controls.
Unit 4: Purple Teaming and Defensive Improvement
Section 4.1: The Blue Team's Role (Detection)- Detecting and responding to Red Team activities (the role of the SOC/IR).
- Analyzing logs and EDR alerts to reconstruct the Red Team's actions.
- Developing and refining SIEM and EDR detection rules (Detection Engineering).
- Measuring the Mean Time to Detect (MTTD) the Red Team.
- Conducting collaborative sessions between Red and Blue Teams.
- Real-time testing and refinement of defensive controls.
- Developing comprehensive security control validation tests.
- Using automation (e.g., Atomic Red Team, Caldera) for continuous simulation.
Unit 5: Reporting, Governance, and Maturity
Section 5.1: Reporting and Remediation- Structuring the Red Team report for executive and technical audiences.
- Focusing the report on TTPs, control gaps, and business impact.
- Developing a formal Plan of Action and Milestones (POAM) for identified gaps.
- Integrating simulation findings into the overall security risk register.
- Establishing a formal, continuous Threat-Led Security program.
- Governance and oversight of external Red Team engagements.
- Metrics for measuring the success and ROI of Adversary Simulation.
- Developing internal Red Team capability and talent.
