• Periodic Observation Report "SOC Report"[717KB]

  As usual, this report looks at security incidents on which IIJ's SOC focused its attention from among those that occurred in 2023. This is followed by two discussions looking at the SOC's efforts to address certain challenges. The first looks at challenges with the Data Analytics Platform that the SOC operates and the introduction of a tool called dbt.
  The second discusses a method of enabling the visualization of C&C communications with a focus on time interval variability.

• Focused Research(1) "Research on a Method of Constructing Sender Reputation"[320KB]

  The IIJ Research Laboratory conducts research on methods for building sender reputation. This article discusses a paper published in the journal of the Information Processing Society of Japan. The paper describes a sender reputation construction method and feedback loop. In this article, I focus on the sender reputation aspect of the paper.

• Focused Research(2) "IIJ and the Evolution of Data Centers-Commemorating 30 Years"[4.36MB]

  The article walks through IIJ's data center initiatives through the years, from the 1990s and the dawn of the Internet era through to the 2020s and the rise of demands for carbon neutrality and AI in the data center.
  Technology has evolved substantially over the past 30 years, and the Internet and society at large have undergone huge changes.
  Data centers are an important piece of the infrastructure that has underpinned those changes, and we look back on those 30 years with the strong sense that they will continue to play that role in the future. I encourage you to read through.
