Select a NOSQL database (MongoDB, Cassandra, DynamoDB, BigTable, etc...) and write a paper describing its security features. In particular, you should discuss:
- access control (which model is implemented, granularity of the access control...)
- encryption (What is encrypted (data-at-rest, in memory, in transit), key management, ...)
- user authentication
- protection against injections
- support for auditing and testing
