The application belongs to the technical field of
information security, and provides a
software development
information security management method based on distributed
backup, which comprises the following steps: obtaining online duration of nodes participating in distributed
backup, process participation degree data, and analyzing and
processing to identify active nodes in
software development information; based on sensitive data types of
software development scenes, a sensitive data feature
library is constructed, a deep
packet detection technology is used to match the sensitive data feature
library, and sensitive data of active nodes are identified; transmission flow of sensitive data in active nodes is obtained, quantitative deviation analysis is performed on sensitive
data transmission flow of active nodes, and transmission
exposure risk of active nodes is evaluated; and the application provides multi-level and full-cycle reliable support for sensitive
data security of distributed
backup software development scenes.
