Let's dive into the fundamental concepts and principles that govern CTI field. We will focus on understanding the complexities of cyber threats, the tools and techniques used by attackers, and the strategies employed by
defenders to protect against these threats.

Key terms:

-Threat actors: Who are the individuals, groups, or nation-states behind cyber attacks?
- Indicators of compromise (IOCs): How do attackers leave digital footprints that can be detected and analyzed?
- TTPs ( Tactics, Techniques, and Procedures): What methods do attackers use to breach systems and steal data?

This goal is to help you gain a deeper understanding of the CTI process and its importance in cybersecurity. By the end of this lecture, you'll be equipped with the knowledge to make informed decisions about your own online security and that of others.
