- Cyber threat intelligence (CTI) involves the collection, analysis, and dissemination of information about current and potential cyber threats.
- It helps organisations anticipate, understand, and mitigate the risks posed by cyber threats, enhancing their overall security posture.
Cyber threat intelligence is the process of gathering and analysing data on cyber threats to provide actionable insights for organisations. It focuses on understanding the tactics, techniques, and procedures (TTPs) of cyber adversaries, enabling proactive defence measures. CTI is essential for identifying potential attacks, understanding threat actors’ motives, and enhancing incident response strategies.
Types of cyber threat intelligence
Strategic intelligence: Strategic intelligence provides high-level insights into the overall cyber threat landscape. It helps decision-makers understand broad trends, such as emerging threats, geopolitical factors, and the evolution of cybercrime. This type of intelligence is used for long-term planning and policy-making.
Tactical intelligence: Tactical intelligence focuses on the specific TTPs used by cyber adversaries. It includes details such as malware signatures, attack vectors, and indicators of compromise (IOCs). This information is crucial for security teams to detect and respond to threats effectively.
Operational intelligence: Operational intelligence provides real-time information about active cyber threats. It includes data on ongoing attacks, threat actor activities, and incident reports. This type of intelligence is used to inform immediate security actions and incident response efforts.
Technical intelligence: Technical intelligence delves into the technical aspects of cyber threats, including vulnerabilities, exploits, and the infrastructure used by attackers. It provides detailed information that helps in understanding how specific attacks are carried out and how to defend against them.

Importance of cyber threat intelligence
Proactive defence: By understanding the methods and motives of cyber attackers, organisations can take proactive measures to defend their networks. CTI enables security teams to anticipate attacks and implement protective measures before threats materialise.
Enhanced incident response: CTI provides valuable context during a cyber incident, helping security teams to identify the root cause, assess the impact, and respond effectively. It also aids in the recovery process by informing remediation strategies.
Informed decision-making: CTI equips organisational leaders with the information needed to make informed decisions about cybersecurity investments, risk management, and policy development. It helps align security efforts with the specific threats faced by the organisation.
Threat actor profiling: Understanding the motivations, capabilities, and objectives of threat actors allows organisations to prioritise their defences. CTI helps in building threat actor profiles that can guide security strategies and resource allocation.
Cyber threat intelligence is a critical component of modern cybersecurity, providing organisations with the insights needed to understand and combat evolving cyber threats. By leveraging CTI, organisations can improve their security posture, respond more effectively to incidents, and make strategic decisions to protect their digital assets.
