    16. 16. Enhancements inSQL Server 2012SQL Server Audit Framework
    17. 17. • SQL Server Auditing is more resistant to auditing destinationfailures• Audit log records additional T-SQL stack frame information whenavailable• Audit information is filtered before it is written into the audit target• Maximum number of audit files available• Stored procedure - sp_audit_write• New columns in audit related views and functions

    19. 19. Policy Based Mgt Framework
    20. 20. FeatureOverviewPolicy Based Mgt Framework
    21. 21. •A framework which exposes sql servers propertiesas facets, allows you to create conditions whichreport back the status of those facets, and thencreate policies around those conditions.•You can just report on those or enforce them. Youcan also import and export them and apply them tomultiple servers.Policy Based Management

    26. 26. The Audit Feature is enhanced in SQL Server2012It is a tool in the “Security and Compliance”arsenalIt needs to be architected into the overalloperational strategy, alongside strategictools, policies and processes.

REGISTER NOW ANDGET 10% OFFDISCOUNT CODE:CHMTD12(Valid until December 10, 2012)• A Preconference Day with 5-7 paralleltechnical workshops, focussed on criticalrole-based skills for Data Professionals.• Two days of conference seminars across 3technical tracks:- Database Administration- Business Intelligence- Data Platform Application Development.Check out www.databasedays.com
    28. 28. Questions?Wrap-Up
    29. 29. Can Enterprise Roles be Audited? EgAdministrators?• yes, but not out of the box. Adeeper look at how AD groupsand segregations of rights areimplemented is needed, and theapplication of auditing againstthese should then be done.Which Editions is audit available on?• All editions, but with limitations.Enterprise Edition allows formore granular auditing that isunavailable in the other SKU’sWhich SKU’s is PBM available on?Why would reducing the queue delay to 0in the Audit properties have an negativeeffect on performance?• Reducing the delay to 0 tells theaudit feature to work in synchronousmode, so every write to the logneeds to be persisted before it isreleased. This essentially has asimilar effect to what the transactionlog has on the system from a commitperspective.• Also, if flushes occur too frequently, itmay have detrimental effects as thedisk subsystem may be slow oroverloaded.• When set to say 10,000 (10 seconds) itwill only flush the buffer if it is full, orit has reached the timer valuespecified.
