March 11, 2008 - Imperva announced that its SecureSphere Database Security Gateways now automatically identify and alert organizations to suspicious changes to sensitive database values right down to the row level. Unlike trigger-based approaches that require intrusive modifications to the database, SecureSphere uses redo logs to transparently monitor changes and pinpoint the users who execute them.
Tracking the most minute changes to database values is imperative for security, compliance and fraud prevention purposes. The Sarbanes-Oxley (SOX) Act specifically mandates that publicly-traded companies control changes to financial information. Unauthorized changes to databases can lead to long and complex forensic investigations to uncover what data changed and restore the original values.
With its track value changes capability, SecureSphere monitors and audits the values of a specific record or a subset of table rows both before and after changes are made. Combined with this granular visibility, SecureSphere allows organizations to set independent controls that generate alerts when changes made to data values violate pre-established policies or thresholds.
