■ The Reality: AWS Security Measures Are Being Postponed to Avoid Disrupting Live Services
For SaaS, e-commerce, and web services—where 24/7 operation is essential—the speed of feature development and service improvements directly impacts business growth.
At the same time, despite understanding the importance of security, many companies delay AWS security initiatives due to:
• Fear of impacting production environments
• Unwillingness to slow down development speed
• Inability to assign dedicated personnel
• Uncertainty about where to begin
As a result, many organizations find themselves in situations where:
• They haven’t clearly defined which security measures to prioritize
• They’ve implemented tools like Security Hub, GuardDuty, and Inspector, but operations haven’t stabilized

In recent years, the need to explain security implementation and operational frameworks has increased, driven by customer audits, compliance with SOC2 and ISMS, and the Ministry of Economy, Trade and Industry’s supply chain security evaluation system.
Therefore, it’s no longer sufficient to say, “We’re safe because we’ve implemented Security Hub and GuardDuty.” The focus must shift to how these tools are effectively and consistently operated.

■ More Companies Struggle to Determine What to Implement and How to Operate
The widespread adoption of AWS-native security features has enabled many companies to use Security Hub, GuardDuty, and Inspector.
However, in practice, teams face challenges such as:
• Uncertainty about where to start
• Receiving alerts but not knowing which to prioritize
• Inability to assess whether alerts indicate real threats
• Hesitation to act immediately due to concerns about production impact
• Over-reliance on specific individuals for initial response during nights or holidays
Consequently, many organizations fail to prioritize actions, leaving them stuck in a cycle of uncertainty—“We don’t know what to do next” or “We implemented tools, but operations aren’t sustainable.”
This isn’t just a lack of tools, but a deeper issue in operational design: not knowing what to prioritize, being unable to make decisions after detection, and failing to sustain operations.
Moreover, involvement in security operations is no longer limited to IT departments. Product operations, service planning, and back-office teams are increasingly expected to contribute to security as part of service quality and customer requirements, making it an organizational-wide challenge.

■ A Step-by-Step Approach: From Implementation to Sustainable Operation
This seminar will go beyond mere tool implementation and focus on building systems for continuous, sustainable operations.
The first half will cover practical approaches to “what and in what order to implement and inventory without disrupting live services.”
The second half will present the optimal framework for “how to sustain operations without over-relying on individuals.”
Specifically, we’ll address common on-the-ground challenges such as:
• What should be implemented?
• Why are AWS security operations often delayed?
• Why do alert responses stall?
• Why do operations become siloed?
• In what order should capabilities be built?
We’ll explain practical, AWS-native security approaches while organizing these issues. Additionally, rather than attempting to implement everything at once, we’ll clearly explain—using real-world support cases—how to sequentially build capabilities in areas like configuration monitoring, vulnerability detection, and threat identification, and how to connect them to sustainable operations.

Whether you’re just beginning to consider AWS security or already use Security Hub, GuardDuty, and Inspector but face operational challenges, this seminar will provide valuable insights to help you define your own path forward.

• Recommended for:
• Leaders of SaaS, e-commerce, or web services aiming to strengthen security without sacrificing development speed
• IT, infrastructure, or SRE teams seeking to reduce siloed operations and operational burden
• Product operations or service planning teams looking to improve service quality and meet customer requirements
• DX or cloud transformation leads aiming to build sustainable security frameworks
• Teams using Security Hub, GuardDuty, or Inspector but struggling with alert response and prioritization
• Organizations considering AWS security but unsure where to begin
• Teams preparing for customer audits, SOC2/ISMS compliance, or supply chain security evaluation requirements

• Key Takeaways from This Seminar
Effective AWS security isn’t just about implementing tools.
It’s crucial to clarify: what to implement, what to prioritize, and how to sustain operations—then embed this into a system your organization can maintain.
This seminar will help you understand the structural reasons why operations stall amid increasing detections and alerts, and provide practical insights for building continuous monitoring and operational frameworks.
If you’re thinking, “I want to improve security but don’t know where to start,” or “We’ve implemented tools, but operations aren’t working,” we strongly encourage your participation.
