What is Threat Intelligence? Beginner’s Guide

Threat intelligence, or cyber threat intelligence (CTI), is specialized data that offers insights about cybersecurity threats faced by an organization. Its main goal is to facilitate proactive defense strategies, ensuring potential threats are addressed even before they manifest.

The primary aim of threat intelligence is to empower organizations with knowledge, allowing them to pre-emptively deal with cyber threats, detect ongoing attacks, and effectively respond to security incidents.

The process of generating threat intelligence involves:

  • Gathering raw data from multiple sources.
  • Correlating and analyzing the data to identify patterns, trends, and relationships.
  • Providing insights on potential or ongoing threats.

Good threat intelligence is:

  • Organization-Specific: It is tailor-made to address vulnerabilities in a specific organization's infrastructure and network.
  • Detailed and Contextual: It delves deep into the nature of the threat, the possible threat actors, their modus operandi (TTPs), and potential signs of a breach (IoCs).
  • Actionable: Instead of just being informative, it offers actionable insights that security teams can directly implement to fortify their defenses.

As per the IBM report, In 2023, the worldwide average expense of a data breach rose to USD 4.45 million, marking a 15% growth from the previous three years.

A major part of this cost comes from the detection and escalation phases. Cyber threat intelligence can significantly reduce these costs by enabling swift detection, thus potentially saving organizations millions of dollars.

Cyber threat intelligence is a critical aspect of modern cybersecurity, acting as an early warning system. By understanding potential adversaries and their methods, organizations can not only shield themselves more effectively but also navigate the complex cybersecurity landscape with more confidence and clarity.
