■ Rapidly increasing risk of ransomware attacks on externally exposed assets, especially targeting 'vulnerabilities in unmanaged assets'
While the spread of the internet and cloud services, the increase in IoT (Internet of Things) devices, and the utilization of technologies like big data and artificial intelligence enrich our lives, the risk of cyberattacks targeting IT assets exposed to the internet is growing. In particular, damage from ransomware attacks has rapidly increased in recent years. According to a survey by the National Police Agency's Cyber Police Bureau, over 80% of infection routes for companies and organizations affected by ransomware were 'intrusions via VPN or remote desktop devices.' Attackers utilize 'OSINT techniques (data collection and analysis techniques using public information)' to investigate the security status of externally exposed assets that serve as entry points for cyberattacks. Externally exposed IT assets include websites and servers launched by business divisions, and cloud services used by employees for work, which IT administrators may not fully grasp. Among these, many assets are left in a state of weak security, and their vulnerability can be easily discovered with a simple investigation.
■ Enormous costs for security diagnostics, how should company-wide asset information be grasped and managed?
'Security diagnostics' play a crucial role in protecting organizations from such cyberattacks. Generally, security diagnostics refer to investigations and inspections to discover vulnerabilities in systems, networks, and web applications, and to assess attack risks. However, many systems and services are updated daily, and new vulnerabilities can constantly arise due to configuration changes or new releases, so a one-time diagnosis is insufficient. Furthermore, attack methods and vulnerability information evolve daily. It is possible to enhance defense capabilities by re-evaluating based on the latest attack trends and vulnerability information. Moreover, companies with subsidiaries or group companies often struggle with inventorying externally exposed IT assets or grasping the latest status of a large number of IT assets. If company-wide measures cannot be taken after properly understanding these, it will increase the risk of security incidents such as cyberattacks. On the other hand, conducting security diagnostics for all externally exposed assets incurs enormous costs and effort.
■ Explaining key points for 'optimizing diagnostic costs' through efficient vulnerability management
In such a situation, how can organizations protect their IT assets from cyberattacks? In fact, to conduct efficient vulnerability diagnostics while keeping costs down, it is important to 'understand the attacker's modus operandi and respond strategically.' Therefore, this seminar will explain 'why attackers target externally exposed assets' based on the latest trends in cyberattacks, and the importance of understanding externally exposed assets as a first step to strengthening security. Furthermore, based on the attacker's modus operandi, we will propose methods to achieve efficient vulnerability management even with a limited budget. This seminar is especially recommended for those who have 'many sites (domains) across various departments within the organization' or 'challenges in managing many externally exposed IT assets such as subsidiaries and group companies.'
