| Titre | Qu'est-ce que le partage de l'intelligence des menaces de cybersécurité What is Cybersecurity threat intelligence sharing |
| Texte | Knowledge is power and collaboration is key for organizations to continuously adapt and improve their security measures in order to stay ahead of cybercriminals. An effective way to stay ahead is by enhancing an organization\'s security posture through cybersecurity threat intelligence sharing. By exchanging information about potential and existing cyber threats with other organizations, individuals, or entities, organizations can better understand the threat landscape and make informed decisions about their security strategies. In this article, we will explore what threat intelligence sharing is and provide guidance on starting your own program.
How threat intelligence sharing works
Threat intelligence sharing can be compared to a neighborhood watch program, where community members collaborate and share information about suspicious activities, potential threats, and crime incidents to improve the overall safety and security of the neighborhood.
Similarly, threat intelligence sharing is a collaborative process that enables organizations to exchange information such as indicators of compromise (IoCs), tactics, techniques, and procedures (TTPs), and vulnerabilities between each other. It involves gathering threat intelligence from various sources, such as internal network logs, security tools, open-source intelligence (OSINT), commercial threat intelligence feeds, and industry-specific sharing communities like Information Sharing and Analysis Centers (ISACs).
The collected data is then analyzed to identify patterns, trends, and actionable insights, which help organizations understand the threat landscape and make informed decisions about their security strategies.
Addressing threat intelligence sharing legal, regulatory, and privacy concerns
To maintain privacy and foster collaboration, organizations should establish clear guidelines and use standardized protocols like Structured Threat Information Expression (STIX) or Trusted Automated eXchange of Indicator Information (TAXII) when sharing threat intelligence outside the company. This collaborative approach will ultimately improve the security posture of all participating organizations.
Also, participating organizations should work closely with legal and compliance teams to understand the requirements and establish guidelines for sharing threat intelligence while adhering to data privacy regulations and industry-specific compliance standards. Guidelines should include sanitization, anonymization, and encryption techniques to protect sensitive information from being publicly disclosed.
How threat intelligence data is structured
Standardized formats and languages, such as STIX or TAXII, are used to structure the data, ensuring consistency, readability, and easy processing by different tools and systems. Organizations share this threat intelligence through various channels, including email, file transfers, web platforms, or automated protocols like STIX and TAXII. Shared intelligence is then consumed, and appropriate countermeasures are implemented based on the insights gained.
Organizations collaboratively and continuously monitor the effectiveness of their threat intelligence sharing efforts, providing feedback to each other and refining their processes to improve the quality and relevance of the shared data.
Benefits of participating in threat intelligence sharing
Just as neighborhood watch programs promote involvement through community building, shared responsibility, and mutual benefit, threat intelligence sharing programs encourage participation by doing the following:
