Guide to Cyber Threat Information Sharing – hinnat ja saatavuus

As the magnitude and complexity of cyberspace increases, so too does the threat1 landscape. Cyber attacks have increased in both frequency and sophistication resulting in significant challenges to organizations that must defend their infrastructure from attacks by capable adversaries. These adversaries range from individual attackers to well-resourced groups operating as part of a criminal enterprise or on behalf of a nation-state. These adversaries are persistent, motivated, and agile; and employ a variety of tactics, techniques, and procedures (TTPs) to compromise systems, disrupt services, commit financial fraud, expose sensitive information, and steal intellectual property. To enhance incident response actions and bolster cyber defenses, organizations must harness the collective wisdom of peer organizations through information sharing and coordinated incident response. This publication expands upon the guidance introduced in Section 4, Coordination and Information Sharing of NIST Special Publication (SP) 800-61, Computer Security Incident Handling Guide and explores information sharing, coordination, and collaboration as part of the incident response life cycle. This publication assists organizations in establishing, participating in, and maintaining information sharing relationships throughout the incident response life cycle. The publication explores the benefits and challenges of coordination and sharing, presents the strengths and weaknesses of various information sharing architectures, clarifies the importance of trust, and introduces specific data handling considerations. The goal of the publication is to provide guidance that improves the efficiency and effectiveness of defensive cyber operations and incident response activities, by introducing safe and effective information sharing practices, examining the value of standard data formats and transport protocols to foster greater interoperability, and providing guidance on the planning, implementation, and maintenance of information sharing programs.
