Organizations face a lot of threats in their day-to-day basics. Cyber threat intelligence is the evidence-based knowledge about existing and emerging hazards to assets that helps organizations make better decisions about defending and mitigating against cyber-based threats.
Threat intelligence is the process of collecting, analyzing, and classifying data using tools and techniques to generate meaningful information about the existing and emerging threats targeting organizations and helps to decide what can be done to mitigate risk. This information collects from OSINT (Open Source Intelligence), human intelligence, malware analysis, and government and private sector information feeds.
Cyber Threat Intelligence is categorized into three types:
Strategic Threat Intelligence.
Tactical Threat Intelligence.
Operational Threat Intelligence.
Strategic Threat Intelligence:
Strategic Threat Intelligence is high-level information that helps to understand adversary intent and make informed decisions to ensure appropriate security in alignment with risk. This information enables security teams to plan for and mitigate existing and emerging threats. The sources of Strategic threat intelligence include internal policy documents, news reports, white papers, or other research material for security organizations.
Tactical Threat Intelligence:
Tactical Threat Intelligence helps professionals understand how the adversaries are expected to carry out the attack on the organization and the technical capabilities and goals of the attacks along with the attack vectors. It has information about indicators of compromise (IOCs), tactics, techniques, and procedures (TTP) used by threat actors. The tactical intelligence component enforces consideration of the broader context of each threat instead of just treating each threat separately.
Operational Threat Intelligence:
Operational Intelligence describes more structural information about specific threats against the organization. It provides information about the threat actor's tools, methodologies, and techniques for a specific threat and its potential risk. This information gives insight into how to build defense mechanisms to mitigate those attacks.
