SISA stands for "Structured Information Sharing and Analysis", a term primarily used in the field of cybersecurity and information technology. It refers to a collaborative process of collecting, analyzing, and sharing data and information related to potential or actual cyber threats, vulnerabilities, and incidents.
In essence, SISA involves the establishment of information sharing and analysis organizations (ISAOs) or frameworks where participants, such as government agencies, private companies, and non-profit entities, collaborate to exchange cybersecurity intelligence. The purpose is to enhance the overall security posture by collectively identifying and responding to cyber risks and attacks more effectively and efficiently.
The SISA process typically involves the collection of various types of information, including threat intelligence, security alerts, incident reports, and vulnerability assessments. This data is then analyzed and disseminated among the participating entities, allowing them to have a broader understanding of the current threat landscape and potential vulnerabilities.
Through SISA, organizations can benefit from shared expertise, best practices, and valuable insights to strengthen their own cybersecurity defenses. It enables stakeholders to proactively identify emerging threats, efficiently respond to incidents, prioritize security investments, and develop appropriate defensive strategies.
Overall, SISA serves as a vital mechanism for fostering collaboration, improving situational awareness, and promoting cybersecurity resilience among diverse entities in both public and private sectors.
