Encrypted Indices?


(Parag Shah) #1

Hi all,

I know ElasticSearch does not support encrypting indices. Has anyone 

built something on top of ElasticSearch or modified ElasticSearch to
achieve encrypted indices? Would like to hear stories of how it went and
how the performance is.

Thanks in advance
Parag

Hi Parag,

I have seen a few implementations of encrypted Lucene indices, but they are largely experimental from what I can tell. There are no Elasticsearch implementations as far as I know.

If you require strong encryption your best bet is to store your Elasticsearch indices on an encrypted filesystem.

Best,
Andrew

If you stick to non-analyzed term queries, you can always encrypt your data
before it is index and then encrypt the query terms that are to be matched.
The hashes of the terms will match, but if you use one-way hashing, the
original data representation cannot be recovered. Somewhat kludgy and the
burden of maintaining the hash key is now simply at another layer.

Use Linux Disk encryption (LUKS) and trusted computers for encrypting files.

Block device encryption is outside the scope of Lucene.
