Cyber Threat Intelligence: Current Trends and Future Perspectives

Many organizations are continually put in danger by sophisticated and malevolent cyber attacks in today's rapidly developing threat landscape, which is evolving at a rapid rate. Cybercriminals, who are more skilled, more organized, and have more financial resources than in the past. Cyber Threat Intelligence, abbreviated as CTI, has emerged as a popular topic and is now being considered by many organizations as a potential solution to the growing number of cyber attacks. The purpose of this work is to conduct a literature review on the previous research that has been done on CTI. The most fundamental question about what CTI is investigated through the process of doing a literature study. This is done by contrasting several definitions in order to identify areas of agreement and disagreement. It has been discovered that neither the organization nor the suppliers have a comprehensive grasp of the information that is deemed to be CTI; hence, further study is required in order to define CTI. This article also listed existing CTI products and services, including as threat intelligence data feeds, threat intelligence standards, and tools that are being utilized in CTI. This study outlines four research issues in cyber threat intelligence and assesses contemporary work carried out in each of those areas. These difficulties were determined based on an assessment of the CTI definition, standards, and technologies. When an organization is inundated with a massive amount of threat data, the need for trained threat data analysts who are able to fully utilize CTI and transform the data into actionable information becomes more vital than it has ever been before. The problem of poor data quality is not a recent development; nonetheless, because to the increasing use of CTI, further study in this field is required.
