7. Importance of Compliance
• Widely cited within the academic
community, 87% of the US
population is uniquely identifiable
by the three attributes of zip
code, birth date, and gender
(Sweeney, 2002)
• Sweeney was able to identify the
medical records of Gov William
Weld (MA) by joining masked
medical data and a voter’s list.

11. Payment Credit Industry (PCI)
Guidance
Addressing Security and Compliance Issues

12. Disclaimers
• I am not a QSA (Qualified Security Assessor)
• But I will provide guidance and best practice on
PCI DSS Compliance.
• No feature
deep dive
• More detailed
info available
in this
whitepaper

13. Overview of the PCI DSS
• Visa, Mastercard, AmEx, Discover, and JCB created the PCI
Security Standards Council in Dec. 2004 and released the PCI Data
Security Standard v1
• Created “to help facilitate the broad adoption of consistent data
security measures on a global basis” for enhancing payment account
data security
• Applies to any business that stores, processes, or transmits Primary
Account Number (PAN)
• Requires annual compliance audit
• Noncompliance leads to levy of significant fines.
• Latest version is 1.2.1,

• Requirement 2: Do not use vendor-supplied defaults for system passwords and other security parameters
Protect Cardholder Data
• Requirement 3: Protect stored cardholder data
• Requirement 4: Encrypt transmission of cardholder data across open, public networks
Maintain a Vulnerability Management Program
• Requirement 5: Use and regularly update anti-virus software

16. Req 2: Do not use vendor-supplied defaults
for system pwds and other security params
• No default passwords in SQL Server
• Features/services Off-by-Default
• E.g., protocols, CLR, dbmail, XPcmdshell
• BUILTIN/Administrators are not sysadmin
• sa account is not enabled in Windows
Auth mode

17. Req 3: Protect stored cardholder data
• Enable Transparent Data Encryption on
databases containing credit card data
• Periodic key rotation – at least once a year
• EKM for split-key ownership
• HSM administrator different from db_owner and
sysadmin
• Key management without EKM permissible
• No single user with access to both db
backup and certificate backup files

18. Req 4: Encrypt transmission of cardholder
data across open, public networks
• Full support for TLS/SSL
• Can be set server-wide or on a per connection
basis.
• Enable for all connections transmitting
cardholder data
SSL
LOGIN
Userid
Password
...

19. Req 7: Restrict access to cardholder data by
business need-to-know
• Limit inclusion in sysadmin
• Windows authentication
• BUILTIN/Administrators are not sysadmin
• Using principals of least privilege
• Role-based access
• Instance and database permissions
• Signed modules
• Disable sa login

20. Req 8: Assign a unique ID to each person
with computer access
• SQL Server uses Windows SIDs for Windows
users and groups
• SQL Logins use GUID for generating SID
• Enable Windows password policy support
• Set to change password on next logon
• Enforce 90 day password expiration
• Do not use a single login for application
connections (or any shared accounts in
general); applies to sa – disable!

21. Req 10: Track and monitor all access to
network resources and cardholder data
• SQL Server Audit to monitor data access
• Granular auditing of tables
• Audit trail must be retained for 1 year
• Log should be protected from SQL users/DBA
• Configure Audit to shutdown on failure
• Change Data Capture to record committed
changes to data
• Policy-based Management to monitor server
settings and detect changes

22. Audit Settings
• At a minimum, Audit:
• Login success and failures
• Changes to server configurations, encryption keys,
logins, server level permissions, databases
• CREATE/DELETE/ALTER of schema objects
• SELECT/INSERT/UPDATE/DELETE and ALTER of
tables containing cardholder data
• Changes to Audit configuration
• Enable the CDC against any table containing
cardholder data

23. Achieving PCI Compliance
• With careful planning, proper organizational
procedures, and process controls, PCI
compliance with SQL Server 2008 attainable
• TDE, Audit, PBM and other 2008 features are
all useful tools in achieving compliance
• Take time to read the whitepaper
• http://www.parentebeard.com/lib/pdf/Deploying_
SQL_Server_2008_Based_on_PCI_DSS.pdf
• Consult a PCI Qualified Security Assessor

24. Health Information Portability and
Accountability Act (HIPPA) Case
Study
Addressing Security and Compliance Issues

25. Business Drivers
• Avoiding disruptions in patient care
• Improving patient and staff access to medical records
and other vital information
• Complying with HIPAA regulations
• Maintaining privacy of medical information
• Its Expensive To Be Careless!
o Direct Costs – Customers lost, Revenue, Legal,
Audit Fees
o Indirect Losses – Reputation

26. The Challenges
 Protecting the privacy and integrity of
patient medical records
 Monitoring database access and capturing
access information for compliance and
audit purposes
 Who accessed which databases, when and
how?

27. What we can and can’t do
 We can ….
 Enforce account/password policy
 Define strong policies and procedures
 We can’t …..
 Enforce audit log in every vendor application
 Determine who is doing what and when

28. How we are providing for data integrity
and security
 Database classifications (AAA vs. AA)
 Have policies and procedures for data access authorization
 Online HIPAA and Security employee training
 Automatically terminate data access when employees leave
 Create scripts to collect data and user access details
 Implement our Centralized Audit Solution on SQL Server
2008

29. Implementing IT Control with SQL
Server 2008
• Securing the Platform
• Controlling Identity and Separation of Duties
• Encrypting Database Data
• Auditing Sensitive Information
• Using Policy-Based Management to Define,
Deploy and Validate Policy

30. Securing the Platform
• Limit number of users have access to SQL Server
• Minimize surface area of attack by limiting running services,
installing only the software needed, disable unnecessary
ports and configuring the firewall
• Install latest OS/SQL service packs and security patches

31. Controlling Identity and Separation of
Duties
• Limit who can access the database and grant the least
privileges.
• Use Windows Authentication
• Use Policy-Based Management to validate security policies

32. Encrypting Database Data
• Transparent Data Encryption (TDE)
• Protecting sensitive data
