Memory data register

(also Data buffer register)

Memory data register definition

In cybersecurity, “The memory data register” (MDR) is part of a computer’s central processing unit, also known as (CPU). MDR holds the information fetched from the main memory. It operates as a buffer between CPU and memory and facilitates efficient data transfer during particular operations and processing.

MDR applications in cybersecurity

  • Data leak prevention: Memory data registers can facilitate data leak prevention techniques and mechanisms by keeping the data temporarily, reducing the risks of sensitive information being left in memory for long periods. This process minimizes the potential of unauthorized access to sensitive data.
  • Malware analysis: During the malware analysis, MDR suspends and holds sections of malicious code extracted from the memory, allowing the analysis algorithms to examine the code’s characteristics and behavior in the system.
