Cyber Threat Intelligence
Cyber threat intelligence (CTI) is the process of collecting and analyzing information about potential cyber threats and adversaries in order to proactively protect against them. This includes gathering data on the tactics, techniques, and procedures (TTPs) used by attackers, as well as identifying and monitoring known malicious actors and their capabilities.
Benefits of Cyber Threat Intelligence
- Early warning: CTI can help organizations identify potential threats and vulnerabilities before they are exploited by attackers, allowing for early warning and proactive defense measures.
- Improved situational awareness: By collecting and analyzing data about potential threats and adversaries, organizations can gain a better understanding of the threat landscape and their own vulnerabilities.
- Enhanced incident response: CTI can help organizations improve their incident response capabilities by providing more detailed information about the nature of an attack and the techniques used by the attackers.
Sources and Collection Methods for Cyber Threat Intelligence
There are many sources of CTI, including:
- Open-source intelligence (OSINT): Information that is publicly available on the internet, such as news articles, social media posts, and security blogs.
- Human intelligence (HUMINT): Information that is gathered through human sources, such as employees, contractors, or other insiders.
- Technical intelligence (TECHINT): Information that is gathered through technical means, such as network traffic analysis, malware analysis, and vulnerability scanning.
CTI can be collected through a variety of methods, including:
- Automated collection: Using tools and technologies to automatically collect and analyze data from various sources.
- Manual collection: Conducting research and analysis manually, such as by reviewing public reports and news articles.
Analysis and Sharing of Cyber Threat Intelligence
Once collected, CTI must be analyzed and shared with relevant stakeholders in order to be effective. This can involve:
- Threat modeling: Analyzing the collected data to identify potential threats and vulnerabilities.
- Contextualization: Providing additional context and background information to help stakeholders understand the significance of the threats and vulnerabilities.
- Prioritization: Prioritizing threats and vulnerabilities based on their severity and likelihood of occurrence.
- Dissemination: Sharing the CTI with relevant stakeholders, such as security teams, executives, and partners.
Effective CTI analysis and sharing can help organizations stay ahead of potential threats and better protect themselves against cyber attacks.
