[Case Study Company Presentation] Seminar on Business Operations That Continued Despite Ransomware Attacks

Background of the Seminar

Ransomware attacks and damage are increasing year by year and are no longer something that happens to others. On the other hand, there are few opportunities to hear directly from those involved about how companies that have actually faced damage made initial decisions and how they protected owners and residents without stopping operations. Choosing what kind of systems to select and how to prepare during peacetime is the deciding factor in whether you can continue operations without interruption and protect the assets and personal information of owners and residents during an emergency.

Seminar Overview

In this seminar, a practical manager from Aoyama Main Planning Co., Ltd., which actually faced ransomware damage, will speak and convey real-time information about on-site response and daily preparations. Through a case study where business data on cloud SaaS was spared from damage even while internal servers and PCs were affected, and payment operations to owners could be carried out without delay, we will concretely explain the effectiveness of "uninterrupted business operations" and business continuity provided by the SaaS system.

I-Seikatsu's Security Measures

Our company continues to protect customer data "structurally" through the following three pillars:

1. Structural Separation

Our office (internal environment) and the data vault (SaaS environment) that manages customer data are completely separated, like "separate islands across the sea." Even if an internal PC is infected with a virus, secondary infections are structurally blocked because the path to the SaaS environment is structurally cut off.

2. Zero Trust (Note 2)

We adopt a zero-trust architecture based on the premise of "not trusting anyone," and employ a model that verifies all internal access each time, similar to airport security checks. Multi-factor authentication (MFA) is thoroughly implemented, and strict identity verification is always performed.

3. Cloud Native (Note 3)

Unlike methods that use RDP (remote operation), we consistently adopt methods using browsers and API communication. Only limited instruction data is passed through, and mechanisms like drive sharing, which are major infection routes for viruses, do not exist, thus structurally eliminating risk.

In addition, I-Seikatsu has acquired three international certifications: ISO/IEC 27001 (ISMS) for information security standards, ISO/IEC 27017 (ISMS-CLS) for cloud security standards, and ISO/IEC 20000 (ITSMS) for IT service management standards, and continues strict operations.

I-Seikatsu is not just a software vendor but a strategic partner that prioritizes customer business continuity, and will continue to provide a "non-stop real estate operations platform" in the future.

*1 BPaaS: Abbreviation for Business Process as a Service, which is outsourcing business processes on the cloud. *2 Zero Trust: A concept that abandons the traditional assumption of goodwill that "internal networks are safe" and instead "suspects all access and verifies it each time." *3 Cloud Native: A system designed and built from the ground up to run on the cloud, rather than simply placing existing software in a cloud "location."
