SECURE DATA CENTER UPDATE AND MONITORING

SECURE DATA CENTER UPDATE AND MONITORING A system hash for each production system is generated. Each system hash includes a concatenation of a hardware hash and a software hash of each production system in the datacenter. A datacenter hash tree is created based on a combination of the system hashes. A test copy of the software hash of each of the production systems is created in respective test systems in the datacenter. In response to detecting a change in the datacenter hash tree, a modification in a system hash which resulted in the change is identified. The central copy of the software hash is compared with the test copy of the software hash. In response to a mismatch between the central copy and the test copy, occurrence of an unauthorized attack in a software of the production system is detected.
