Threat Intelligence Definition:
Threat Intelligence is the collection, analysis, and dissemination of information about current and potential threats to an organisation’s security. It helps organisations understand, predict, and mitigate risks by providing actionable insights into emerging threats, attack tactics, and malicious actors.
What is Threat Intelligence?
Threat Intelligence involves gathering data from a wide range of sources, including threat feeds, security logs, and open-source intelligence (OSINT). This information is then analysed to identify patterns, detect indicators of compromise (IOCs), and provide context about the threat landscape. The goal is to provide a proactive approach to security by staying ahead of attackers.
Why is Threat Intelligence important?
The purpose of Threat Intelligence is to enable organisations to make informed decisions about defending against cyber threats. By understanding who is likely to attack, how they operate, and what they are targeting, organisations can better allocate resources, implement effective defences, and respond to incidents more efficiently.
How does Threat Intelligence work?
Threat Intelligence is generated through a combination of automated data collection, threat analysis, and human expertise. Security teams use tools like SIEM (Security Information and Event Management) systems, threat feeds, and specialised platforms to aggregate and analyse threat data. Threat Intelligence can be tactical (e.g., specific IOCs), operational (e.g., attack methods), or strategic (e.g., trends and Risk Assessments).
Threat Intelligence Examples:
Examples of Threat Intelligence include identifying new Phishing campaigns targeting specific industries, tracking the activities of Advanced Persistent Threat (APT) groups, and analysing indicators of compromise (e.g., IP addresses, file Hashes) associated with Malware. Threat Intelligence helps organisations block malicious IP addresses, update Firewall rules, and enhance their Incident Response efforts.
Threat Intelligence Issues:
Challenges in Threat Intelligence include managing large volumes of data, distinguishing between relevant and irrelevant threats, and ensuring timely analysis. Effective Threat Intelligence requires collaboration, strong analysis capabilities, and constant updates to stay current with the rapidly evolving threat landscape.
