What is Threat Intelligence?
Threat intelligence is collecting, analyzing, and using information about potential and active threats to an organization's security.
Think of it like a spy gathering information for a government agency, but instead, the spy's target is cyber criminals and their tactics, techniques, and procedures (TTPs). The information gathered is then used to protect the organization from future attacks.
For example, let's say there is a new malware that has been targeting financial institutions. A threat intelligence team would research this malware and learn how it spreads, what it does, and what its weaknesses are. The organization would then share this information with the security team to protect themselves, such as patching vulnerabilities, updating firewalls, or training employees to spot and avoid malware.
The goal of threat intelligence is to stay one step ahead of the bad guys and ensure the security and resilience of the organization.
The Importance of Threat Intelligence
Threat intelligence is crucial for organizations because it provides a comprehensive understanding of the threat landscape, including knowledge of attack surfaces.
An attack surface refers to how an attacker can potentially gain access to a target system or network. Attackers can include open ports, software vulnerabilities, or human weaknesses like phishing attacks.
Threat intelligence helps organizations understand their attack surface by providing insights into cyber criminals' tactics, techniques, and procedures (TTPs). This information identifies areas of vulnerability and develops strategies to defend against attacks.
For example, a threat intelligence report might reveal that a particular type of malware exploits a specific vulnerability in a widely used software application. Armed with this knowledge, the organization can patch the vulnerability and train employees to recognize and avoid malware.
In addition to providing information about attack surfaces, threat intelligence also helps organizations stay informed about emerging threats and the latest tactics used by cybercriminals. The gaining of information enables them to quickly adapt their defenses and stay ahead of the constantly evolving threat landscape.
Overall, threat intelligence is critical to an organization's security strategy. It provides a comprehensive understanding of the threat landscape and the knowledge needed to defend against current and future threats. By staying informed about the latest attack surfaces and emerging threats, organizations can reduce risk, improve incident response, and minimize the impact of security incidents.
