Synchronous replication for system and data security

A system comprising:

• means for replicating an operation on data from first data storage in a first security domain to second data storage in a second security domain, wherein
• the first security domain and the second security domain are independent of one another,
• the first security domain permits a first host in the first security domain to directly access the first data storage, and
• the first security domain prohibits a second host in the second security domain from directly accessing the first data storage;
• means for awaiting a receipt of an acknowledgement that the operation on the data has been completed in the second security domain;
• and
• means for completing the operation on the data in the first security domain in response to the receipt of the acknowledgement that the operation on the data has been completed in the second security domain, wherein the completing the operation in the second security domain comprises completing the operation on the data in second data storage in the second security domain.

A system comprising:

• a replication module configured to replicate an operation on data from first data storage in a first security domain to second data storage in a second security domain, wherein
• the first security domain and the second security domain are independent of one another,
• the first security domain permits a first host in the first security domain to directly access the first data storage, and
• the first security domain prohibits a second host in the second security domain from directly accessing the first data storage;
• a receiving module configured to await a receipt of an acknowledgement that the operation on the data has been completed in the second security domain;
• and
• a completion module configured to complete the operation on the data in the first security domain in response to the receipt of the acknowledgement that the operation on the data has been completed in the second security domain, wherein the completing the operation in the second security domain comprises completing the operation on the data in second data storage in the second security domain.

A computer-readable medium comprising:

• replicating instructions configured to replicate an operation on data from first data storage in a first security domain to second data storage in a second security domain, wherein
• the first security domain and the second security domain are independent of one another,
• the first security domain permits a first host in the first security domain to directly access the first data storage, and
• the first security domain prohibits a second host in the second security domain from directly accessing the first data storage;
• awaiting a receipt of an acknowledgement that the operation on the data has been completed in the second security domain;
• and
• completing instructions configured to complete the operation on the data in the first security domain in response to the receipt of the acknowledgement that the operation on the data has been completed in the second security domain, wherein the completing the operation in the second security domain comprises completing the operation on the data in second data storage in the second security domain.
