Search indices store enough information about your data for a hacker to reconstruct highly confidential documents, including Personally Identifiable Information (PII) and Protected Health Information (PHI), which are subject to regulatory mandates. In addition, because search indices are stored in plaintext, hosting enterprise search platforms in the cloud exposes companies to even larger risks.
SearchStax's seamless and turnkey integration with Credeon enables highly secure cloud-based Solr application.
To prevent the risk of a data breach from search indices, Hitachi’s patented searchable encryption technology allows the search process to be carried out directly on encrypted data. Specifically, Credeon:
Credeon Secure Full-text Search functions as a plugin module for SearchStax Solr-as-a-Service. The systems architecture and product components are shown in the diagram below
Credeon uses an AES 256 cryptographic module (FIPS 140-2 certified) and a probabilistic encryption scheme using 128-bit randomization process. This process makes the encrypted data resistant to advanced statistical attacks and virtually eliminates the risk of the plaintext being derived from the ciphertext.
The combination of homomorphic functions and a symmetric-key encryption scheme achieves a real-time encrypted search with an average of just 15 percent + overhead compared to a regular search
Encryption keys are managed independent of SearchStax by Measured Search to ensure only the customer have access to the data.
