Advanced query history
Query history captures details about the user activity on the Netezza Performance Server system, such as the queries that are run, query plans, table access, column access, session creation, and failed authentication requests. This section describes the advanced query features used with the new security capabilities.
- Guaranteed audit capture of all operations
- Digital signing of audit data
- Audit data stored in row-secure tables
- Secure data offload to a different Netezza Performance Server system, lowering the impact on a production system and improving the security of the audit
