Threat intelligence is any cybersecurity risk information that businesses may utilise to better understand their entire threat environment. Threat intelligence data could, for instance, comprise details about the network's present health, the detection of IoCs such aberrant account activity, abnormal web traffic patterns, and other anomalies, or recently found zero-day vulnerabilities.

Continuous data streams called threat intelligence feeds contain threat data gathered by artificial intelligence. These feeds give enterprises the ability to proactively protect against assaults by providing information about cybersecurity risks and trends in real-time. Security teams can make adjustments to their security posture based on this knowledge to better understand the strategies, techniques, and processes used by potential hackers.

There are several free threat intelligence feeds available, including the following:

  1. Automated Indicator Sharing of the Cybersecurity & Infrastructure Security Agency (AIS)
  2. InfraGard SANS Internet Storm Center of the FBI
  3. Browse safely on Google
  4. Utilizing threat data and turning it into useful insights is also made feasible by integrating these feeds into a security platform.

Threat intelligence feeds gather information:

Data may be gathered for each threat intelligence feed from a variety of sources. A few potential sources are as follows:

  • Open-source information gathered and disseminated by cybersecurity experts
  • Customer telemetry data from security firms that compile it from a variety of users and organisations
  • searching the internet for attacks and vulnerabilities
  • Running discovered malware in a secure sandbox can help you learn the characteristics of malware.
  • Open-source threat intelligence feeds frequently concentrate on a single security domain or threat type, combining information from several sources and streaming it in real-time. Time is of the importance when it comes to preventing threats to the network, hence the feed's real-time nature is essential.

Types of threat intelligence:

Strategic:  For less technical audiences, this kind of threat intelligence provides high-level analyses. It could provide details on how the threat will affect businesses as well as how it ties into larger patterns in the threat environment. The majority of strategic threat intelligence is gathered through public sources including white papers and studies, as well as local and national media.

Tactical: This kind concentrates on IoCs to allow for the quick detection and removal of threats. Tactical threat intelligence is easier to produce and frequently automated. It is frequently regarded as the most fundamental type of threat intelligence.

Operational: Investigating the specifics of prior known assaults yields operational threat intelligence. Security teams may learn more about the motivations and complexity of threat actors by comprehending the specifics of "who?," "what?," and "how? ".
