Webinar Held on "Increasing Importance of SIEM/XDR, High Costs as an Implementation Barrier"

Logs are Acquired, Yet Signs of Attack Go Unnoticed — The Necessity of Cross-Analysis with SIEM/XDR Many companies acquire logs from major devices such as AD, VPN, Firewall, and Proxy. However, if these logs are managed individually, it is difficult to grasp the signs of an attack as a single flow. Recent cyberattacks are increasingly occurring not only as rapid intrusions but also as gradual progressions over several days or months. Each individual behavior may appear as "common operation," making it difficult to identify anomalies without cross-sectional and time-series analysis of traces distributed across multiple systems. Therefore, the importance of SIEM/XDR, which centrally manages collected logs and detects anomalies early through correlation analysis, is increasing.

Wanting to Start Integrated Log Management, but Commercial SIEM/XDR's "High Cost" is a Bottleneck — The Implementation Wall Facing SMEs Even if the necessity of SIEM/XDR is understood, commercial products tend to be expensive, posing a significant budget barrier for SMEs. Even if a commercial product can be introduced, high hurdles such as log ingestion design, alert tuning, and securing operational personnel remain, leading to the separate challenge of "it won't run even if implemented." As a result, many companies feel the importance of integrated log management but fail to take the first step, leaving their countermeasures stalled. What SMEs need are realistic options that allow for a low-cost start and can be managed reasonably with their own resources.

Overcoming the "Implementation Barrier" — How to Start Low-Cost Integrated Log Management and Initial Detection with OSS "Wazuh" This seminar will organize the necessity of SIEM/XDR and explain the challenges in starting integrated log management, such as the cost perception of commercial SIEM/XDR. Furthermore, as a solution to these challenges, we will explain how to utilize "Wazuh," an open-source integrated security platform that can be started at a low cost. The content will provide a concrete operational image of integrated log management and initial detection, including detection examples (brute-force attacks, DNS tunneling, etc.) using "Wazuh."

As a system integrator (SIer), we are constantly observing the front lines of障害対応 (troubleshooting) and operations. Therefore, we provide comprehensive support not only for building Wazuh but also for realistic alert design tailored to each customer's network configuration and operational structure, creating operational manuals, tuning rules, and proposing additional measures. Additionally, our ability to perform cause analysis and propose improvements based on the entire network, not just Wazuh alone, is a feature of Force System.

Leveraging OSS and the agility unique to an IT venture, we provide support that makes it easy to start at a low cost and continues until operations can be managed after implementation. This is the value of Force System's Wazuh implementation and operational support.

"I'm worried about implementing and operating Wazuh on my own." "I want to start at a low cost, but I'm concerned if we can sustain its use in practice." We will convey practical methods for companies like these, looking ahead from implementation to operational stabilization.
