The lab researches technologies that protect information systems from cyberattacks.
AboutAbout the lab
Building secure, high-performance information infrastructure.
The Information Systems Security Lab conducts research on realizing secure, high-performance information infrastructure, with a focus on cybersecurity.
Its main themes include Moving Target Defense (MTD), threat traces for reproducing and analyzing attacks, and dynamic malware analysis.
In addition to examining theory, the lab places importance on implementation and evaluation, and also builds practical skills through study sessions, round-robin reading seminars, and team participation in CTFs.
On the lab's website, it is introduced under the name "Koide Lab."
Key terms
- Moving Target Defense
- A defense approach that dynamically changes a system's settings and configuration so that the target of an attack is not fixed, making attacks less likely to succeed
- Threat Trace
- Simulation and tracing technology that reproduces and analyzes the behavior and impact of attacks to support the study of countermeasures
- CTF
- A competition-style exercise in which participants compete in information security knowledge and skills
- APT Attack
- An attack in which the attacker stays in a compromised system for a long period and quietly exfiltrates data
ResearchResearch themes
As the spread of the Internet connects every kind of system in society to networks, cyberattacks targeting companies, governments, and organizations are increasing. The lab analyzes the conditions under which attacks succeed and the scope of their impact, and works on designing and evaluating defense technologies that can be used in real environments.
*Illustrative imageAnalyzing and Defending Against Cyberattacks
To protect the confidentiality, integrity, and availability of information assets, the lab analyzes the conditions under which attacks succeed and the scope of their impact. It then designs and evaluates defense technologies that can be applied to real environments.
*Illustrative imageMTD: Moving the Target of an Attack
This is a defense approach that, for example, changes a server's IP address, network configuration, or software configuration over time to undermine the assumptions an attack relies on. The lab applies it across multiple IT domains, aiming to achieve both defensive performance and low operational burden.
*Illustrative imagePredicting the Behavior of Malware After Intrusion
The lab predicts the activity of malware, such as that used in APT attacks, after it has intruded into a system, and clarifies what is needed to stop attacks and prevent information leaks. It represents the malware and its operating environment with models and analyzes its behavior through simulation.
*Illustrative imageAttack Detection for Web Applications
The lab builds into the frameworks that underlie web applications functions for detecting attacks and for guiding attacks to a honeypot, then implements and evaluates them. It aims for attack detection tailored to the characteristics of each application.
