First Things First
 Security Awareness
 Data Classification
 Risk Assessments

Security Awareness
Establish
Policies
Educate
Staff
Enforce
Compliance

Awareness
Training
Monitoring

Security Awareness
 Staff are required to go through security
awareness training every year
 Last year we purchased SANs training Securing
the Human
 Prior years – IT Division has developed training
and focused on:


IT policies
Current security events that have occurred in
public

Security Awareness Emphasis
SecUrity is everyone's responsibility
and "U" are at the center.
Make sure U are not the weakest link

7
Security Awareness Emphasis
Be a good example to entities that you audit.
We should be setting the example for good
SecUrity

Data Classification
 Once you have trained ~ need to make sure all
Data is Classified.
 Data classification – classifying the data based on
its level of sensitivity/confidentiality and the
impact to our office in the event the data is
disclosed, altered or destroyed without
authorization.
 The classification of data helps determine what
baseline security controls are appropriate for
safeguarding that data.

9
Data Classification
 GA Department of Audits is in the process of
classifying all our confidential data
 Developing a Department Catalog to identify
datasets and business owners

Questions to ask
 Where is my sensitive/confidential data?
 Can I manage all copies & versions of confidential data?
 Is all confidential data appropriately protected?
 Who can access confidential data?
 Is confidential data required for audit?
 Is confidential data being sent or transferred out (email
and/or removable media)
 Are correct security processes being applied to confidential
data?
 What about retention of confidential data?

What should be kept confidential?
Risk Assessment
 After we do a Data Classification we will be doing a
risk assessment




Select a risk assessment methodology ( a repeatable
process)
Use data classification information
Determine gaps in security
Assess potential risks, threats and vulnerabilities
Risk = Likelihood * Impact

15
Risk Assessment
If there was a Breach make sure you think about things
such as:




Reputation
Credibility
Cost to investigate
Credit monitoring services for those
affected

GA State Law 50-6-29

Obtaining Confidential Data
 Give DOAA Confidentiality Form to Entity
 Sometimes entity wants to modify form
Especially in regard to how long we can keep data
 The entity’s lawyer usually wants to get involved
 Federal law supersedes State Law
 Data and system may be with 3rd Party
 Try to get data well in advance of start of audit
 Entity stall Practices
 Too big
 Wrong format


23
Transmitting Confidential Data
 For most transfers we use a product called
Accellion Secure File Transfer
 If large Dataset will give the entity an encrypted
drive to copy data to

24
Storing Confidential Data
 Encryption





In Oracle – work with business owner to make sure
field level encryption is on datasets
Laptops – use PGP to encrypt all laptops
Flash Drives– for HIPAA data encrypt all Flash
Drives with PGP
Looking at BitLocker to start encrypting all DOAA
Flash Drives and possibly laptops
Backups are encrypted

25
Using Confidential Data
 In Oracle DB – if have to decrypt data fields–
email sent to IT and Manager of project to alert
that data fields were decrypted
 DLP – Data Loss Prevention – use Cisco’s
appliance – for email DLP violations


Notification sent to ISO and IT Director if a DLP
violation – make sure it is not false positive
Employee’s Director notified of any DLP violation
in order to guide employees’ behavior to be more
security conscious

26
Destroying Confidential Data
 Destruction of Data – auditor’s responsible for
destroying confidential data at the end of audit or,
if needed for work papers, at the end of the
retention period of 5 years.


Auditors are provided with software (PGP Shredder)
that facilitates the destruction of confidential electronic
data by overwriting the data with random text and
repeats this process through multiple passes.
Records managers in each Division ensure compliance

Additional tools
 Evaluating a product called Sensitive Data
Manager by Identity Finder
