Cyber Threat Intelligence Definition:
Cyber Threat Intelligence (CTI) is the process of collecting, analysing, and disseminating information about current and emerging cyber threats. The goal of CTI is to provide actionable insights that help organisations understand and mitigate security risks by making informed decisions on protecting their assets, systems, and data.
What is Cyber Threat Intelligence?
CTI encompasses data and analysis regarding Threat Actors, their motivations, tactics, techniques, and procedures (TTPs). It focuses on identifying potential threats and vulnerabilities that could impact an organisation, enabling proactive defence measures. CTI can be divided into different types, such as strategic, tactical, operational, and technical intelligence, each offering different levels of detail and focus areas.
Why is Cyber Threat Intelligence important?
The purpose of Cyber Threat Intelligence is to enhance an organisation’s ability to predict, detect, and respond to cyber threats by understanding the threat landscape. CTI enables security teams to identify and prioritise threats, adapt their defences, and prevent potential attacks. By leveraging CTI, organisations can better allocate resources, improve Incident Response, and stay ahead of cyber adversaries.
How does Cyber Threat Intelligence work?
CTI is gathered from a variety of sources, such as threat feeds, security researchers, Dark Web monitoring, and internal data analysis. Threat Intelligence platforms (TIPs) aggregate and analyse this data to provide contextual insights on threats. Security teams use CTI to create threat profiles, identify indicators of compromise (IoCs), and develop threat hunting strategies and response plans. Sharing Threat Intelligence within industry groups or with external partners can also strengthen collective defences.
Cyber Threat Intelligence Examples:
Examples of CTI include analysing a Phishing campaign's characteristics to identify future targets, using Threat Intelligence feeds to block known malicious IP addresses or domains, and leveraging information about adversary techniques from frameworks like MITRE ATT&CK to improve defence strategies. CTI reports may detail specific campaigns, Exploit trends, or indicators to watch for.
Cyber Threat Intelligence Issues:
Challenges with CTI include managing the volume of threat data, ensuring its relevance and accuracy, and effectively integrating intelligence into existing security workflows. Sharing intelligence across organisations and industries can be hindered by trust issues or legal and regulatory concerns. Organisations must balance automation and human analysis to derive actionable insights from threat data.
