The lab observes and analyzes networks to support safety and security in cyberspace.
AboutAbout the lab
Keeping networks healthy, just as we look after our own health
The Security and Software Lab studies how to observe and analyze networks and the Internet in order to contribute to safety and security in cyberspace.
Just as we learn about our health in the physical world and take action based on it, the lab emphasizes understanding the state and environment of cyberspace and linking that understanding to countermeasures.
The lab calls this approach “cyber health management.”
In addition to network traffic, the lab collects and analyzes information on DNS, the Web, servers, and certificates.
Key terms
- Cyber health management
- This lab’s approach of observing and analyzing networks and the Internet to understand their state and environment, and using that understanding to take countermeasures
- DNS
- A mechanism on the Internet for looking up the destination to connect to from a domain name
ResearchResearch themes
Based on the idea that, in cyberspace too, it is important to understand the state and environment and connect that understanding to appropriate countermeasures, the lab conducts research on “cyber health management.” This research observes and analyzes networks and the Internet and links the results to safety and security.
*Illustrative imageUnderstanding the normal state of a network
The lab observes networks and systems to investigate what state they are normally in. From large amounts of data, it looks for clues to unusual activity or changes and interprets what they mean.
*Illustrative imageExamining the surrounding environment
Because safety is not determined by the target alone, the lab collects and analyzes information about the surrounding environment that supports communication and services, such as DNS, the Web, servers, and certificates.
*Illustrative imageTurning findings into countermeasures
The lab connects what it learns from observation and analysis to the responses that are needed. It interprets the relationship between a target and its surrounding environment, and considers countermeasures and mechanisms while thinking about their effects and impacts.
*Illustrative imageCollecting and analyzing data
Targeting information such as network traffic, DNS, the Web, servers, and certificates, the lab builds mechanisms for collecting data and finds states, changes, and characteristics in large volumes of data. It also designs and implements the measurement and analysis software and systems that are needed.
