            Hackers Landscape

• Today’s hackers are organized, motivated, and
  sophisticated. Data and identity theft is no longer for
  amateurs.

• Hackers work on behalf of state sponsored or criminal
  organizations, have access to state-of-the-art tools, and know
  how to target specific organizations for information that can be
  used for financial gain.
Is your Organization Immune to
Data Breach ?
• 340 million records containing personal information have been
  breached in US since 2005 (Privacy Rights Clearing House)
• 85 % of businesses have experienced a data breach (2009
  Ponemon Institute data breach study)
• 50 % of large hospitals experienced at least one data breach in
  2009. ( Source: HIMSS)
Some Massive Data Breaches
       February 2007, information on possibly
       tens of millions of credit and debit cards.
        Credit card information for more than 250,000
        businesses in 2009 – 130 million records
   Contractor recycled Disks without erasing – leaving
   the personal information for millions of veterans
   accessible to whoever got the disc.

     In February 2008, Bank of New York Mellon sent
     10 unencrypted backup tapes to a storage facility and
      lost one tape during the transit.

  Data Breach Readiness

When it comes to a data breach, the question is
not“ if” you will become a target, the question
is “when.” Operational pre-planning and readiness can
control costs, improve customer loyalty and preserve
your reputation and brand.
       Georgia Breach Law
The law requires that "Any information
broker that maintains computerized data that
includes personal information of individuals
shall give notice of any breach of the
security of the system following discovery or
notification of the breach in the security of
the data to any resident of this state whose
unencrypted personal information was, or is
reasonably believed to have been, acquired
by an unauthorized person."
Regulatory Requirements (PCI, HIPAA..)


1. Isolate the breach- for Forensics

2. Inform necessary parties – Law enforcement etc.

3. Notify your business partners (e.g. Bank)

4. Incident Response Report
PCI Incident Response Requirements


 Requirement 12.9:

 12.9.1: Create an incident response plan
 12.9.2: Test the plan at least annually
 12.9.3: Designate specific personnel to be available on a 24/7 basis to respond
 to incidents
 12.9.4: Provide appropriate training to staff with security breach response
 responsibilities
 12.9.5: Include alerts from IDS, IPS and file integrity monitoring systems
 12.9.6: Develop processes to modify and evolve the IR plan according to lessons
 learned
A Data Breach Scenario (hypothetical)

Credit card data is compromised at the Airport. The DOA has
to notify the effected customers according to “GA Breach Law
Notification”. The Executive Management at DOA has asked
the Public Relations, Information Security Officer and DOA’s
Attorney to do the following:

   • A press release to the media for the incident
   • A posting on DOA Website for the incident
   • Letter to the effected customers whose
     credit card information have been compromised
       A Perfect Storm

This breach event may become ultimate
nightmare, a “perfect storm” if:

   • DOA Customers learned of the breach via
     sensationalized media reports.
   • DOA was obliged to make public statements in the
     absence of necessary facts.
   • Card Issuers had to act quickly, with little information,
     to notify customers and determine if cards should be
     closed and new cards be re-issued.
      Data Breach Response Strategy

• Inventory of data and information systems is essential to a
  successful security program.
• Data Steering Committee (An Event Response Team)
  consisting of key executives and personnel from areas of the
  business that would be affected by a data breach.
• A Risk Assessment and Response Matrix that guides your
  team in determining how harmful a particular breach event
  would be and how you should respond to it.
• A Communication Plan designed to control outbound
  messaging related to the event and to maintain public
  confidence
Building Your Data Steering
Committee/ Event Response Team
 •   Audit and compliance
 •   Representatives from all customer-facing groups
 •   Human resources
 •   Key executives and senior decision-makers
 •   Legal
 •   Marketing and Public Relations
 •   Operations/information technology
 •   Risk management and Information security
Creating Your Risk Assessment and Response
Matrix

A Solid Communication Plan

• When a breach is contained, announce what you know
when you know it.
• If there are things you do not yet know—perpetrator,
details of attack etc. Avoid spreading misinformation
that you will eventually have to correct or retract.
• Explain why you cannot reveal certain information.
• Describe, in specific detail if possible, what you are
doing and why you are doing it.
• Be honest, above all else. Your customers and partners
will appreciate it.
  Bad-News Management Plan

• Prepare for the worst by envisioning the best

• Go from start to finish in words and pictures

• Do a dry run

• Establish leadership contingencies

• Coach and train spokespeople

•Know where everybody is and how to contact him/her
