■ Surge in Ransomware Attack Risks on Externally Exposed Assets, Especially Targeting 'Vulnerabilities in Unmanaged Assets'
While our lives have been enriched by 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, the risk of cyberattacks targeting IT assets exposed to the internet is simultaneously increasing.
Particularly in recent years, damages from ransomware attacks have surged. According to a survey by the National Police Agency's Cyber Police Bureau, 'intrusions through VPNs and remote desktop equipment' accounted for over 80% of the infection routes in companies and organizations that suffered ransomware damages.
Attackers use 'OSINT (Open Source Intelligence)' techniques to investigate the security status of externally exposed assets, which serve as the entry points for cyberattacks.
Externally exposed IT assets include websites and servers independently launched by business departments, and cloud services used by employees for work, which the IT department on the management side cannot fully grasp. Among these, there are sporadically assets left in a weak security state, which can be easily identified as vulnerable with a simple investigation.
■ Enormous Costs of Security Diagnostics: How Should Company-Wide Asset Information Be Grasped and Managed?
To protect one's organization from such cyberattacks, 'security diagnostics' play a crucial role. Generally, security diagnostics refer to investigations and inspections aimed at finding vulnerabilities existing in systems, networks, and web applications to assess attack risks.
However, since many systems and services are updated daily, and there is always a possibility of new vulnerabilities arising from configuration changes or new releases, a single diagnosis is insufficient. Moreover, attack methods and vulnerability information evolve daily. Defensive capabilities can be enhanced by re-evaluating based on the latest attack trends and vulnerability information. Furthermore, in companies with subsidiaries and group companies, issues occur such as failing to inventory externally exposed IT assets or being unable to grasp the latest status of a massive amount of IT assets.
Failing to properly grasp these and implement company-wide countermeasures increases the risk of security incidents like cyberattacks. On the other hand, attempting to conduct security diagnostics on all externally exposed assets practically incurs enormous costs and effort.
■ Explaining Key Points of 'Diagnostic Cost Optimization' Through Efficient Vulnerability Management
Under these circumstances, what should be done to protect an organization's IT assets from cyberattacks? Actually, to implement vulnerability diagnostics efficiently while keeping costs down, it is important to 'understand the behavioral principles of attackers and respond strategically.'
Therefore, in this seminar, based on the latest trends in cyberattacks, we will explain 'why attackers target externally exposed assets' and the importance of grasping externally exposed assets as the first step in strengthening security.
Furthermore, taking the attacker's behavioral principles into account, we will propose methods to realize efficient vulnerability management even with a limited budget. This seminar is highly recommended for those who face challenges such as 'having a massive amount of sites (domains) across various departments within the organization' or 'managing many externally exposed IT assets including those of subsidiaries and group companies'. If you want to know the key points of 'diagnostic cost optimization' through efficient vulnerability management, please join us.
