Cyber threat intelligence is knowledge, skills and experience-based information concerning the occurrence and assessment of threats or harmful events occurring in cyberspace. It helps organizations mitigate risk by allowing them to understand the attack surface of their networks and to better defend against attackers. It also allows them to improve their overall security posture by staying abreast of the tactics, techniques and procedures (TTPs) that adversaries use to successfully breach their systems.
Cyber threat intelligence intel is often derived from a variety of sources, including open-source and commercial threat feeds. It can also be gathered from information-sharing communities, where analysts from different organizations share firsthand experiences and insights on current or emerging attacks. This raw data can then be used to create actionable cyber threat intelligence.

Once this information is processed, it can be filtered and analyzed for the specific needs of an organization. For example, a cybersecurity team may only want to focus on certain indicators of compromise (IoCs), such as file hashes, IP addresses, suspicious domains and phishing emails. Other times, they may want to monitor all IoCs and other information, such as vulnerabilities or phishing email headers.
Regardless of the level of detail an organization requires, they can rely on threat intelligence to help them make informed decisions that will improve their security posture. This can help them reduce risks, mitigate the impact of an incident and ensure they meet regulatory compliance requirements. However, a good cyber threat intelligence program is an iterative process. To get the most out of it, a business should have clear goals and objectives, which can be changed over time.
