How did the most recent data
breaches happen?
Which are the most embarrassing
for the the IT Profession?
…for the developer profession?

What about Dev, Ops, Data,
and Security?
Is it after 25 May?
What year?

Data Models
• Karen’s Preference
• Track all kinds of
metadata
• Advanced Compare
features
• Support DevOps and
Iterative development
• Support Conceptual,
Logical and Physical
design Karen Lopez - www.datamodel.com - @datachick

Normal
Conflicts..
Developers vs. Data Quality
Data Professionals vs. Development Speed
Data vs. Code
Data vs. Metadata
Software Defined vs. Data Defined

Karen’s Data Governance Position
Data security at the data level
Models & catalogs capture security/privacy needs
Design security from the start
Measurement & monitoring
In other words, governance

Typical DevOps Security Focuses
Code Reviews Auditing
Key and Secrets
Management
Repositories …what else?

What’s actually in that database?
What’s actually in that JSON/XML?
Where did the test data come from?

What did I just post to Github?

What do we have?
Where is it? How do we
know?

Data Profiling vs. Data Naming

Data Curation

Stewardship
Covers more than Data
Categorization
Important part of Data
Governance
New-ish term going into
GDPR and other
protection concepts

One more time…
Every Design
Decision must be
based on Cost,
Benefit and Risk

Data Curation
• Takes time, but…
• Builds on other efforts
• Contributes to future efforts

Catalog Data
Assets
Every compliance effort starts with
inventory
Capture the hard work of every project
Build incrementally
Start with what exists physically

Azure Data Catalog
Azure Data Catalog is a
fully managed cloud
service whose users can
discover the data sources
they need and
understand the data
sources they find. At the
same time, Data Catalog
helps organizations get
more value from their
existing investments.

What sorts of data do
we steward? How
should we protect it?

Issues
• Data Pros spend 80% of their
time sourcing, prepping and
cleansing data
• Likely everyone else has these
issues
• We are lousy at documenting
data and meta data
• This makes Karen sad

Dynamic Data Masking

Privacy - Dynamic Data Masking
CREATE TABLE Membership(
MemberID int IDENTITY PRIMARY KEY,
FirstName varchar(100) MASKED WITH (FUNCTION =
'partial(1,"XXXXXXX",0)') NULL,
LastName varchar(100) NOT NULL,
Phone# varchar(12) MASKED WITH (FUNCTION = 'default()') NULL,
Email varchar(100) MASKED WITH (FUNCTION = 'email()') NULL);
INSERT Membership (FirstName, LastName, Phone#, Email) VALUES
('Roberto', 'Tamburello', '555.123.4567', 'RTamburello@contoso.com'),
('Janice', 'Galvin', '555.123.4568', 'JGalvin@contoso.com.co'),
('Zheng', 'Mu', '555.123.4569', 'ZMu@contoso.net');

Column level
Data in the database, at
rest, is not masked
Meant to complement
other methods
Performed at the end of
a database query right
before data returned

Masking in
SQL Server
4
functions
available.
today
• Default
• Email
• Custom String
• Random

Data in database is
not changed
0101
Ad-hoc queries
*can* expose data
0202
Does not aim to
prevent users from
exposing pieces of
sensitive data
0303

Why would a Data Pro love it?
• Allows central, reusable design for
standard masking
• Offers more reliable masking and
more usable masking
• Applies across applications
• Removes whining about “we can
do that later”

Security – Row Level Security

Security –
Row Level
Security
Filtering result sets (predicate-based
access)
Predicates applied when reading data
Can be used to block write access
User defined policies tied to inline table
functions

Row Level Security
No indication that results have been filtered
If all rows are filtered than NULL set returned
For block predicates, an error returned
Works even if you are dbo or db_owner role

• Allows a designer to do this sort of
data protection IN THE DATABASE,
not just rely on code.
• Many, many pieces of code
• Applies across applications

Always!
Security – Always Encrypted

Security – Always Encrypted
ENABLED AT COLUMN LEVEL PROTECTS DATA AT REST
*AND* IN MEMORY
USES COLUMN MASTER KEY
(CLIENT) AND COLUMN
ENCRYPTION KEY (SERVER)

Always Encrypted

Security –
Always
Encrypted
Foreign keys must match
encryption types
Client code needs to support
AE (currently this means .NET
4.x)

Security –
Always
Encrypted
Wizard

• Always Encrypted, yeah.
• Allows designers to not only specify
which columns need to be
protected, but how.
• Parameters are encrypted as well
• Built in to the engine, easier for
Devs

What should we STOP doing?
Nobody ever talks about this….

SQL Injection
• WE ARE STILL DOING THIS!
• IT’S STILL THE #1 (but
unsecured storage is
getting more popular)
• TEST. TEST SOME MORE
• Automated Testing
• Governance is important

Unprotected “buckets”
“I’LL DELETE IT ONCE
YOU GRAB THAT FILE”
SHARING WITH 2ND
PARTIES
SHARING WITH 3RD

Trusting good people
Good people don’t always stay that way
People mess up
Monitoring
Checking
Automatic alerting

Karen’s Rant Topic for
2019

Test Data
• Restoring Production to
Development
• Restoring Production, with
Masking
• Restoring Production, with
Randomizing
• Restoring
Production…anywhere
• Design Test Data
• Lorem Ipsum for Data
• Really, Design Test Data

Building a
Culture of
Data Security
& Privacy
• Reward
identification of
threats
• Reward
identification of risks
• Trust, but always cut
the deck
• Monitor, test,
monitor, test,
monitor…
• Be a customer with
your data in there
• Don’t use
production data
for anything other
than production
and support
