Research of Existing Osint Tools and Approaches in the Context of Personal and State Information Security

The article examines modern tools and approaches to conducting OSINT — the analysis of open sources of information. The key role of OSINT, along with other intelligence methods such as HUMINT, IMINT, SIGINT, MASINT and GEOINT, lies in creating a holistic information field that combines open, technical, human and geospatial sources. The constant development of methodologies and improvement of automation tools allows to increase the efficiency and accuracy of the analysis of the received information, which makes OSINT one of the most important elements of modern intelligence.
The study examined the main data sources, such as public registers, social networks, news resources, geospatial data and other open resources. The key stages of collecting, analyzing and processing information, which is an integral part of OSINT research, are highlighted.
Special attention is paid to Geospatial Intelligence tools with a comparative description of the most common solutions. Their functional capabilities, advantages, limitations and areas of application are investigated.
An analysis of popular OSINT tools, such as ‘Maltego’, ‘Shodan’, and platforms for monitoring social media was conducted. The latest approaches were analyzed, including the use of artificial intelligence, automation of analysis processes and ensuring data transparency.
The article assessed the degree of threat to personal data and confidential information in the context of OSINT. It was determined which data requires protection, and appropriate measures were provided to minimize risks, which will include classifying data by confidentiality level.
Effective strategies for countering OSINT were proposed, in particular in terms of detecting and neutralizing information leaks, using adequate data protection tools, including encryption, monitoring systems and access auditing, and development prospects in the conditions of a modern information society were outlined.
