Title
Assistant Professor
Profile
Research topics * Information service administration/monitoring/optimization for better service quality Information services are abundant in the Internet. In Kyushu University, there are various kinds of information and communication services for faculty and students through campus network, too. Due to rapidly inflating service infrastructure, some servers tend to be overlooked and are under-performing. Virtualization technology allows to introduce new services more easily, but it introduces more layers and complexity for administration. I'm studying to improve the situation through experiences of the real service administration and operation. * Intrusion and back door detection based on network traffic monitoring Incidents and its damage caused by malicious activities over the Internet is increasing. To protect users from these activities, we need layered protection among end-nodes and network itself. In this research, I focus on network-level countermeasures. As a backbone administrator of an organization, I'm studying methods to observe and detect malicious activities inside our own network. To achieve this, I'm studying methods to classify network traffic at the edge of our network without using specific signatures. Using such methods, I want to detect unknown or malicious activities which are hard to detect by traditional signature based intrusion detection system. * other activities I'm working on administration and maintanance of Kyushu University campus network, including detection of malicious activities inside our network, and enlightenment of end users about network security, etc.

    At Kyushu University, Information Infrastructure Initiative provides an email se

    Office 365 Exchange Online. On September 20th, 2019, Microsoft announced the en

    ulnerable to identity leakages such as phishing and malware attacks. Microsoft w
    ould require users to use Modern Authentication such as Exchange protocol or OAu
    th 2.0 authorization with IMAP, POP, and SMTP. Historically we had instructed ou
    r users to use IMAP or POP and SMTP protocols for their email applications, incl
    uding Microsoft Outlook and Mozilla Thunderbird, so disabling Basic Authenticati
    on would significantly impact our user population. In September 2021, Microsoft
    announced the end of September 2022 as the hard deadline for disabling Basic Aut
    hentication. Based on available information, we prepared migration documents fro
    m Basic Authentication to Modern Authentication and started to notify users to a
    bandon Basic Authentication. Sending messages to users did not seem to be effect
    ive after a couple of notifications, so we tried to temporarily disable Basic Au
    thentication to realize the remaining users through authentication failures. In
    this paper, we would like to share our experiences about the effect of retiring
    Basic Authentication for Exchange Online on our service and users.

    In Kyushu University, Information Infrastructure Initiative manages a Microsoft 365 tenant for our university members. We started offering Office 365 in 2016 and migrated our university-wide email service to Microsoft 365 Exchange Online in 2018. Due to the recent outbreak of COVID-19, off-campus uses of Microsoft 365 have increased, and concerns about account security arose. We discussed how to deploy Multi-Factor Authentication (MFA) to protect our users. Microsoft 365 comes with Azure Active Directory (Azure AD), and it includes built-in MFA functionality. With the basic Azure AD MFA, individual users can register MFA information anytime but have no control to enable or disable MFA. Tenant administrators need to enable MFA for each account. For a gradual deployment, we want to allow users to enroll in MFA and register information at their convenience. In addition to that, we want to prevent malicious attackers from registering their MFA information if an account should be already compromised. Such control was difficult with the basic Azure AD MFA. Since 2020 our tenant subscribes to Azure AD Premium P2 licenses, which provides Azure AD Conditional Access. Conditional Access enables fine controls of MFA and other user access behavior with security groups. We designed an MFA self-enrolling and configuration system, and implemented it with Microsoft Forms, Power Automate, Conditional Access, and in-house web applications. By design, this system prohibits MFA information registration until user's self-enrollment in MFA, and requests the user to register MFA information upon the next sign-in after the self-enrollment. This is supposed to reduce the possible unauthorized registration of MFA information. We extensively discussed implementation of various measures and preparation of documents to counter users' troubles and complaints. We started deploying MFA in April 2021, but we have not yet fully mandated MFA due to a push back from some executives expressing concern about the adverse effects of enforcing MFA too quickly.

    A Supplementation Method for Delegation of Address Management on a Cloud Email Service
    In providing organizational email service, the use of cloud email services contributes to reducing operation and management costs, generally. In most cloud email services, the management of a certain part of email addresses is not delegatable to administrators of organizational units, but this causes operational load concentration on organizational service administrators in large-scale organizations. For solving this issue, this study aims to enable delegations of email address management to administrators of organizational units. This article introduces a method for delegation of email address management and a supplemental system onto a cloud email service. The proposed method divides the management of email addresses within internet subdomains for organizational units from account administration and delegates the email address management to subdomain administrators. The present system for email address management is designed based on microservice architecture and configured in serverless. This microservice architecture and serverless configuration reduces operation and management costs and contributes to the maintainability and extensibility of the present system. Furthermore, the use of an identity-as-a-service for authentification, authorization and storing privilege information ensures confidentiality and security of system accounts.

    Migrate Legacy Email Services in Kyushu University to Exchange Online.
    In Kyushu University, Information Infrastructure Initiative provides an email service for students and staff members, called “Primary Mail Service”. We had operated an on-premises system for this service, and the lifetime of this system would end in early 2019. We needed to reduce costs for replacing this system because our university had just finished a major campus migration. We compared some options such as building a yet another on-premise system and migrating to a cloud-based email service and finally gave up the on-premise option because we couldn’t afford replacement and operational costs of another on-premises system anymore. We selected Microsoft Exchange Online as the new service mainly because we already had a contract with Microsoft and been operating an Office 365 tenant. We had additional requirements for user provisioning and services which were not available in Exchange Online, so we had to implement and maintain additional systems on top of it. On December 18th, 2018, we successfully migrated the email service to Exchange Online. By coincidence, Kyushu University Administration Bureau decided to migrate their in-house Exchange server to Exchange Online. After some discussions, they concluded to migrate their domain to the same tenant with Primary Mail Service. Other than that, there are more than a hundred legacy email servers inside our campus network operated by various departments as subdomains of kyushu-u.ac.jp. We are designing a plan to consolidate them into our tenant of Exchange Online to reduce a budget and human resource costs, and to improve security. In this presentation, we share our experiences about migrating our campus-wide email services to Exchange Online. We also discuss why we want to consolidate other legacy email servers and how to implement the plan.

    電子メールは古くから用いられているメッセージ交換手段で,依然として世界的に広く利用されている.メールサービスを提供するメールホスティングでは,多数の利用者を同一システムに収容するマルチテナント型によりリソース効率を高め,運用コストを低減している.メールホスティングでは利用可能なグローバルIPアドレス数やメール送信の集中管理のため送信サーバは集約されていることが多いが,大量メール送信や送信先の迷惑メール対策により送信キューの輻輳が発生することで,問題を起こしたテナント以外にも影響が波及し,サービス品質の低下や管理コストの増大をまねいている.本研究では,テナントごとの送信キューの分離と,メール送信の集中管理や送信用グローバルIPアドレスの管理を両立する,メール送信集約用の透過型SMTPプロキシを提案する.また,送信キューの分離によってキュー輻輳時の影響範囲が限定される効果を確認するための予備実験と,透過型SMTPプロキシのプロトタイプ実装について述べる.
