The twenty-four/seven database Oracle Database Security David YahalomSenior database consultant davidy@xpert.com www.xpert.comwww.davidyahalom.com
Security Drivers (and constraints): • Enterprise value resides in Bits (I.P.) not Atoms (factories). Google Vs. Ford. • Data everywhere, must be accurate, fast and available. • Security must be Transparent to the end user. • Security decisions increasingly tied to compliance (regulatory or in-house).
Security Drivers (and constraints): • Network security is well known and understood (VPN, Firewall). • Attackers now going where data resides. • Legitimate and authenticated users are a concern.
Inbound Data • Network Encryption • Strong Authentication • Identity Management • Storage • Transparent Data Encryption • Secure Backup • Monitor • Database Vault. • Audit Vault. • Configuration Scanning. • Access Control • Database Vault • Oracle Label Security • Oracle VPD • Outbound Data • Network Encryption • Data Masking
“A 2007 Oracle survey found that a DBA usually spend less than 7% of total work time on database security.”
Database Security is NOT a one time project.Database Security is a on-going process. • Add a security-focused DBA to the security department.
The secure database solutions: • Oracle Database Vault. • Oracle Advanced Security. • Oracle Audit Vault • Virtual Private Database. • Fine-Grained Auditing. • Secure Backup.

Oracle Security Solution Oracle DatabaseVault
Database Vault: Authoritative security studies have documented that more than 80% of information system data losses and attacks have been perpetrated by 'insiders' — those authorized with some level of access to the system and its data.• 80% of threats come from insiders. • 65% of internal threats are undetected.
Database Vault: Oracle Database Vault addresses common regulatory compliance requirements and reduces the risk of insider threats.
Database Vault: • Preventing highly privileged users (DBA) from accessing application data. • Enforcing separation of duty (DBA can’t create users, view data). • Providing controls over who, when, where and how applications, data and databases can be accessed. • Can be added to existing application environments without changes to the existing application code.

Oracle Security Solution Oracle Virtual Private Database
Virtual Private Database: Also known as Fine Grained Access Control, provides powerful row-level security capabilitiesFor example, VPD can be used restrict access to data during business hours.
Virtual Private Database:Transparently modifying requests for data to present a partial view of the tables to the users based on a set of defined criteria. select * from accounts; changes to: select * from accounts where am_name = BOAZ';
Virtual Private Database: Oracle Label Security – optional add-on for providing easy to use interface for row-level security. No coding needed.
