Threat Intelligence Questions Medium
The main sources of threat intelligence can be categorized into three main categories: open-source intelligence (OSINT), closed-source intelligence (CSINT), and human intelligence (HUMINT).
1. Open-Source Intelligence (OSINT): This refers to information that is publicly available and can be accessed by anyone. OSINT sources include websites, social media platforms, forums, blogs, news articles, public databases, and other publicly accessible information. It provides a broad view of the threat landscape and can help identify emerging threats, vulnerabilities, and indicators of compromise (IOCs).
2. Closed-Source Intelligence (CSINT): Also known as proprietary intelligence, CSINT refers to information that is obtained from commercial sources or private organizations. These sources may include threat intelligence vendors, security research firms, cybersecurity companies, and government agencies. CSINT often provides more detailed and specific threat information, such as advanced persistent threats (APTs), zero-day vulnerabilities, and targeted attacks.
3. Human Intelligence (HUMINT): This involves gathering threat intelligence through human sources, such as cybersecurity experts, threat hunters, incident responders, and law enforcement agencies. HUMINT can provide valuable insights into threat actors, their motivations, tactics, techniques, and procedures (TTPs), as well as their potential targets. It often involves collaboration and information sharing within the cybersecurity community.
It is important to note that threat intelligence is most effective when multiple sources are combined and analyzed together. This allows for a comprehensive understanding of the threat landscape, enabling organizations to proactively detect, prevent, and respond to potential cyber threats.
