■ Preparing for Security Incidents: CSIRT Development is Essential for All Company Sizes
The impact of security incidents like ransomware and supply chain attacks is becoming severe regardless of company size. Establishing a CSIRT (Computer Security Incident Response Team), a system that defines "who," "what," and "in what order" to respond when an incident occurs, is becoming a de facto mandatory requirement. However, in reality, many companies postpone incident preparedness, unable to start CSIRT development due to reasons such as "no experts in-house" or "limited budget for external outsourcing."
What's important now is not to aim for a perfect system from the outset of incident response organization, but a realistic approach: starting with a minimal configuration according to guidelines and gradually increasing maturity through actual training.
■ Reality: Internal lack of know-how and high outsourcing costs hinder progress
Many companies considering CSIRT development often face obstacles where the project itself doesn't even start due to misconceptions like "it can't be started without specialized security personnel" or the reality of "high costs when requesting external consultants." On the other hand, attempting to develop regulations and manuals from scratch internally often leads to a vicious cycle where it's unclear how much detail is sufficient, time is spent on formal document creation, and the crucial "operational system" is never established. Furthermore, practical initiatives such as tabletop exercises and post-incident reviews are often delayed due to lack of know-how, resulting in a continuous state where "there is a system, but it's not functioning."
■ Low-budget, short-term CSIRT development methods and practical tabletop training starting with templates
This seminar introduces practical methods to develop a CSIRT in a short period and at low cost, even without in-house experts, by utilizing templates. By using templates for organizational charts, incident response flows, and role assignment tables based on best practices, companies can save the effort of creating from scratch and focus on customizing to their specific circumstances. Furthermore, it explains, with concrete examples, the steps to progressively enhance CSIRT maturity through a PDCA cycle by utilizing tabletop exercises based on actual incident scenarios, identifying omissions in systems and procedures through training.
