Introduction
•
With the growing complexity of Information Technology, financial institutions are exposed to a greater
number of IT risks.
In 2012 alone, many
Information Security attacks
and operational issues
made national news
headlines:
•
Password File Hacking
Amazon Cloud Outage
SQL Injection Attacks
Mobile Device Attacks
Due to the increased threat, regulators hold companies accountable not only to regulatory requirements but
also to standards of best practices and procedures.
Guidance for regulatory
exams is published;
however, regulators’ focus
changes based on the
current IT trends. For
example, recent hot topics
in Financial Services
include:
•
•
•
•
•
•
•
•
•
Cyber Attacks
Data Leakage
Vendor Management
Disaster Recovery & Business Continuity
Plans
• Data Privacy
IT Risk expertise assists companies in navigating the current threats to their IT environment, and ensures
compliance with regulatory requirements.

IT Risk: In the News
Password File Hacking
SECURITY EVENT
• Since 2002, Information Security breaches have risen exponentially.
• Cyber activity has spiked this year.
• 6/2012: 3 major Password Breaches.
• LinkedIn: 6.4 million hacked passwords.
• Lastfm.com.
• eHarmony.
• Passwords were stored in database using a standard algorithm rather
than encryption.
POSSIBLE RISK MITIGATION
Controls
• Review quality of stored passwords.
• Set up security monitoring procedures that should be able to detect an
attempted breach.
• Establish adequate security perimeter controls.
• Develop a security patch deployment process.
Cost-benefit
• $200,000-300,000: set up adequate, A+ security measures, versus
• $5.5 million: the average cost to a company of a security breach.

Cyber attacks are increasingly more targeted to specific corporations.
Moving from simply making a point to wreaking financial havoc.
Advanced Persistent Threats (APTs) focus on hacking an individual employee rather than the
organization’s infrastructure.
Spear Phishing: hackers obtain a company email list in order to appear as a trusted source.
Example: RSA Spear Phishing Attack in 3/2011– Hackers sent phishing emails appearing to
come from a Recruitment website to employees of RSA.
Attachment in the email placed a malicious file on the employee’s computer, enabling
attackers to gain remote access to the company network and steal information regarding
RSA’s SecurID keyfob products.
Establish effective security patch and virus/malware patch procedures.
Review network security processes to ensure that sufficient restriction exists for access to
business critical applications (either internally or externally hosted).
Perform ongoing penetration testing.
Implement a Computer Emergency Response Team (CERT) process.
Ensure Security Administration (both new hires and existing personnel) have adequate
training.
Ensure that strong password and pin requirements are included and enforced in company
policies.
Evaluate practices used by Help Desk to reduce opportunities for social engineering attacks.

Mitigation
•
Post-9/11, Business Continuity (BCP) and Disaster Recovery (DR) became highlighted areas
for regulatory examiners.
Regulators going beyond the idea of alternate sites to the requirement that enough critical
staff be available for principal trading applications, especially for “market makers.”
Increased use of vendors would require that DR/BCP plans include an appropriate level of
testing.
Include business continuity considerations into the overall design of the business model in
order to reduce the risk of service disruptions.
Ensure plans are robust, detailed, regularly updated, tested and approved by a bank’s
Executive Management.
Include areas such as pandemic crisis management, media communication, hardware
recovery and security measures.
Monitor and analyze the results of testing:
 Identify areas requiring special attention.
 Personnel that could benefit from additional training.

Data Privacy
Data Privacy
•
Differences in global data privacy regulations and standards:
United States
1
Cause
of Risk
•
US government has limited power to
protect citizens’ data privacy.
• Federal Trade Commission rarely takes
action against US companies for privacy
breaches; usually levies small fines.
•
If company has lawful access to data it
may use it, as long as it is not
prohibited (such as under GrammLeach-Bliley Act).
•
Importance of privacy policy /
statement: as long as a customer is
made aware of the policy when data is
collected and does not object, the
company can use it.
•
Patriot Act allows US officials to access
phone, email and financial information
without a warrant.
Europe
•
•
1995 EU Directive on Data Protection
Protects citizens' privacy and states
that permission is required by a
consumer for a company to use or
exchange personal data.
•
2012: EC proposed General Data
Protection Regulation, a draft update
of the Directive.
• Requires reporting a data breach
within 24 hours.
Asia
•
2011 marked a pivotal year in Asia
with the introduction of many data
protection regulations.
•
South Korea: Personal Information
Protection Act considered the most
stringent data privacy regulation globally.

justified.
• Requires data breach notification.
• Conforms data privacy rules across EU.
• Introduces Privacy Impact Assessments.
•
•
US companies would be heavily
penalized for releasing EU citizens’
personal data to US authorities (such
as by complying with National
Security Letters)
•
Hong Kong and the Philippines have
both recently passed significant data
privacy regulations.
• Review data protection control jurisdictions of business activities and verify their adherence to sovereign laws.
2
Risk
Mitigation
• Corroborate that policies support the segregation of company and personal information that might go cross-border.
• Review the security monitoring process, particularly the communication procedure in the event of a security breach.
• Verify that cloud and email storage infrastructure supports infrastructure requirements.
• Ensure that the DR solution is not in violation of regional standards.

IT Risk Program
IT Risk Assessment Methodology
Methodology and Process of an IT Risk Assessment:
•
Conduct in accordance with established industry and regulatory guidance (FFIEC, COBIT, etc., further discussed on slide 16).
In addition to the previously mentioned “Hot Topics” scope should include the following areas:
• Risk Management
• Information Security Administration
• Asset Management
• Human Resources Security
• Physical and Environmental Security
• Network, Communications & Operations Management
• Access Control
• Information Systems Acquisition, Development & Maintenance
• Incident Event & Communications Management
• Compliance
Risk Assessment Process Should Encompass:
• Review existing IT Risk related material in place
• Develop specific control tools (such as the RCM discussed on slide 15)
• Conduct interviews with key IT and IS personnel and management, as well as other relevant staff such as HR, Administration, Audit &
Compliance
IT Risk Assessment Enables Management to:
• Obtain a comprehensive and documented understanding of risks in the IT / IS operational environment
• Grasp the severity and level of urgency for each associated risk
• Appropriately and accordingly take measures to reduce risks in order of priority
• Ensure resources are deployed to address risks that have the most significant implications for the organization at that time
• Plan and budget for projects that mitigate IT / IS risk according to assessed risk and priorities with varying mandates and longevity
• Acknowledge and accept risks not considered by management to pose a significant threat

IT Risk Program
Risk Control Matrix
Risk Control Matrix (RCM) Tool:
•
•
•
•
•
•
Provides a qualitative assessment of the expected controls for each area of the IT environment.
Documents whether relevant control objectives are met.
Identifies open risk issues based on gaps between the required control and the control in place.
Categorizes issues based on a risk rating such as “High” “Medium” and “Low.” The determination of the risk rating is based
on the severity of the risk and the probability of its occurrence.
Determines and tracks management’s decision whether each flagged risk should be remediated, partially remediated,
accepted or a combination.
Prescribes recommendations on steps to address the risk deemed to need mitigation.
