This document discusses information leakage and data loss prevention. It begins by defining information leakage as the intentional or unintentional disclosure of information to unauthorized parties. Information can leak through external hacking, insider leaks, outsourcing partners, or former employees. This leakage can cause financial and reputational loss for organizations. Frameworks like SOX and tools like DLP suites aim to prevent leakage and loss. The conclusion emphasizes the importance for executives to understand leakage risks and utilize prevention techniques and best practices.

2. Agenda
What is Information Leakage?
How and when it occurs?
Impact on organizations
Frameworks & DLP tools
Implications for CA
Conclusion

3. What is Information
Leakage?
Information leakage is an alternate term for
information exposure
Information exposure is the intentional or
unintentional disclosure of information to a party
that does not have access to that information (CWE,
2008)
Common form of data loss
Severity range widely depending on type of
information that is revealed

4. How and when it occurs?
External hack to organization’s confidential
information
Occur during outsourcing
Acts of consultants who works for different firms
concurrently
Relevant to CAs who works as consultants and C-Suite
Executive
Between alliances and collaborating companies
Leak from inside by employees

5. Leak from Inside
Ways information can be leaked:
Flash drives , USB devices, Other “lifestyle” devices
iPods
Bring-Your-Own-Device
Former employees – Internal Control Deficiency
Cyberspace
Online Storage (e.g. Google – Gmail)
Instant messages, emails, blogs

6. Impact on
Organizations
Financial and reputational loss
Small leaks accumulate to big loss
Loss of customer and employee private information
Loss of competitive position
Lawsuits or regulatory consequences

7. Frameworks
The Privacy Act of 1974 – U.S.
The Payment Card Industry Data Security Standards –
U.S.
Sarbanes-Oxley Act (SOX) – U.S.
Federal Information Security Management Act (FISMA)
– U.S.

8. DLP Tools
Full DLP suites
McAfee Data Loss Prevention - Commercial email
security platform
Controls for emails
Websense TruWeb DLP, CISCO IronPort email and
Google – Postini
Stand-alone DLP products
Code Green Networks, intrusion Inc., Workshare

9. Additional DLP Tools
Internal Security Control
Digital forensic techniques
Network Security Solution
E.g. Fidelis Security System’s XPS
Deploy DLP tools as part of larger security suite

10. Implication on CA
Safe environment for internet accounting
information system
Relevant to accounting profession
Third party specialized auditor to appraise system
Effective network security audit

11. Conclusion
Extremely important for C-Suite executives to:
understand information leakage
Realize impact on organizations
Utilize DLP tools
Continuous effort to protect confidential information
Combination of effective DLP implementation and
best management practices
