• Role of threat intelligence in proactive defense

b. Types of Threat Intelligence

• Strategic Intelligence – High-level insights for executives
• Tactical Intelligence – Specific techniques used by attackers
• Operational Intelligence – Real-time analysis of active threats
• Technical Intelligence – Indicators of compromise (IOCs) and attack signatures

c. The Threat Intelligence Lifecycle

1. Planning & Direction – Setting intelligence objectives
2. Collection – Gathering data from various sources
3. Processing & Analysis – Transforming raw data into useful intelligence
4. Dissemination – Sharing intelligence with relevant teams
5. Feedback & Improvement – Refining intelligence for accuracy
