摘要

PROBLEM TO BE SOLVED: To provide a business information protection device allowing enhancement of information security of a business information system and easy management of an access rule for the system.SOLUTION: When a valid work application is applied, a registration determination part 131B gives an application number for uniquely identifying work. A work schedule information retention part 136 retains work schedule information formally registered by the registration determination part 131B. A log retention part 152 retains the application number given by the registration determination part 131B correlated with an access log of work application content corresponding to the application number. A work validation part 151B compares content of the access log of the log retention part 152 with work schedule information retained by the work schedule information retention part 136 corresponding to the application number correlated with the access log, and checks presence of an illegitimate access.SELECTED DRAWING: Figure 2
