A threat intelligence feed is a continuous stream of data that provides information about potential cyber-attacks. Organisations use this feed to update their security systems and prepare for the latest threats. Much like how a news feed updates with fresh information, a threat intelligence feed delivers new data about suspicious activities, malware, and harmful websites that could compromise a system’s security.

The information in a threat intelligence feed is vital for security teams. It helps them detect possible attacks early and respond to them before they can cause damage.
Many threat intelligence feeds are available for free, making them accessible to a wide range of organizations.
What is a cyber threat?
A cyber threat refers to any action that could result in the theft, damage, or unauthorized change of data. Threats can be both actual attacks or potential risks.
To be useful, threat intelligence needs to provide detailed information. This includes:
Tactics, Techniques, and Procedures (TTPs): These describe how attackers operate.
Malware Signatures: These are unique patterns that help identify known malware.
Indicators of Compromise (IoC): These are signs that an attack may be happening or has already occurred.
Suspicious IP addresses or domains: If attacks are traced back to certain locations, security systems can block traffic from these sources.
Where does threat intelligence come from?
The data in a threat intelligence feed can come from many sources, including:
Monitoring internet traffic for signs of attacks
Research done by cybersecurity experts
Direct analysis of malware
Information shared within the security community
Web crawling techniques that identify attack patterns
Analytics collected from various security systems
Companies or vendors compile this information into feeds and distribute it to organizations to help them protect their systems.
Benefits of using threat intelligence feeds
There are several advantages to using threat intelligence feeds:
Up-to-date information: Cybercriminals are constantly changing their tactics to get past security defences. Using a threat intelligence feed ensures that an organization is aware of the latest methods attackers use. This helps security teams block new types of attacks effectively.
Wide range of data: Threat intelligence feeds provide detailed information about various types of attacks. This allows organizations to protect themselves against more threats, improving their overall security.
Improved efficiency: By relying on external sources for threat intelligence, security teams save time. Instead of gathering information on their own, they can focus on analysing the data and deploying strategies to protect their systems.
How are STIX and TAXII used?
STIX and TAXII are standard ways to format and share threat intelligence data. STIX defines how the data is organized, while TAXII provides a method to distribute this information. Many threat intelligence feeds use these standards to ensure their data can be easily read and processed by various security tools.
In summary, threat intelligence feeds play a crucial role in helping organizations defend themselves against cyber-attacks. They provide timely, detailed information that helps security teams stay ahead of emerging threats and make informed decisions about their defences.
