Information Security• Strong Board and Senior Management support

• Integration of security and controls throughout business processes

• Clear accountability for carrying out security responsibilities

• Focus on information and cyber security controls

10

Information Security Program• Robust program

• Risk identification

• Risk measurement

• Risk mitigation

• Risk monitoring and reporting

• Incorporate cybersecurity elements

• Comprehensive testing and assurance to determine the effectiveness of the Program

11

Information Security Program• Integrate processes, people, and technology

• Maintain risk profile in accordance with Board’s risk appetite

• Encompass the entire Bank, not just focus on IT controls

12

Risk Appetite StatementThe Board has established specific strategic goals and objectives as defined in the Organizational Strategic Plan for the Bank. To increase the probability of achieving these goals, the Board has established acceptable risk tolerances within its risk appetite. The Board periodically reviews the risk appetite and associated tolerances and may adjust them to adapt to changing economic conditions, the threat landscape and/or strategic goals.

Overall, the Board desires to maintain enterprise Information/Cyber Security risk mitigation and control strategies that will reduce inherent risk to a moderate or low level as feasible. Specifically relating to the Cyber Security Assessment our goal is maintain a reasonable alignment of our Inherent Risk Level and Cyber Maturity Levels based on the Assessment. When either the enterprise Information/Cyber Security Risk is High or the Cyber Security Assessment levels are out of alignment or high the Board will be notified and kept apprised of the situation until the items are addressed.

13

Information Security Program

• Completion of a Cyber Assessment

• Target Inherent Risk Level and Cyber Maturity Level

• Cyber Security Strategy

• Integration of Cyber Security and Information Security

Enterprise-wide Information Security Risk Assessment

• If Management cannot or chooses not to mitigate a vulnerability should document:

• Decision to accept

• Level of risk associated with the vulnerability

• Person accountable for accepting the risk

15

Risk Measurement• Use threat analysis tools

• Understand and support measurement of information security related risks

• Map threats and vulnerabilities

• Improve consistency in risk measurement

• Highlight potential areas for mitigation

• Select proper controls to cover various attack stages, channels, and assets

• Allow comparisons among threats, events, and potential mitigating controls

16

Risk Mitigation• Develop and implement appropriate plan to mitigate

identified risks

• Understand extent and quality of current control environment

• Consider system controls rather than any discrete control

• Obtain, analyze, and respond to information from sources like FS-ISAC (Threat intelligence gathering)

• Develop, maintain, and update a repository of cybersecurity threats and vulnerability information

17

Inventory and Classification of Assets• Updated Inventory

• Classifies the sensitivity and criticality of assets

• Hardware, software, information, and connections

• High, Medium, Low

• Public, non-public, institution confidential

• Critical and non-critical

• Policies to govern inventory and classification

• Inception and throughout life cycle

18

Interconnectivity Risk• Sharing information with other institutions and third

parties

• Risk

• Misuse

• Mismanagement

• Compromise of connections

19

Mitigation of Interconnectivity Risk • Identify all connections

• Identify all access points and connection types

• Identify connections between and access across low risk and high risk systems

• LAN, ISP, WiFi, cellular

• Assess all connections with third parties that provide remote access or control over internal system

• Implement and access adequacy of controls to ensure security of connections (regardless of criticality or sensitivity)

20

Network Controls• Establish trusted and non-trusted zones; segment

the network

• Implement appropriate controls over wired and wireless networks

• Maintain accurate network diagram and data flow diagrams

• Develop data inventory

21

Network and Data Flow Diagram

• Identify:

• Hardware

• Software

• Network components

• Internal and external connections, including cloud

• Types of information passed between systems to facilitate the development of defense in depth security

29

Logging• Inactive user accounts

31

Configuration Management• Securely maintaining technology by developing

baselines for tracking, controlling, and managingsystem settings
