Information Security Governancefor the Indian Banking Sector

I am very glad that IDRBT is releasing a Handbook on Information Security Governance for the

Indian Banking Sector.

The subject is topical for the contemporary Indian banking sector as banks have made impressive

advances in terms of computerization. This brings with it a different working environment as

compared to that of manual banking. On one hand, it has brought new levels of efficiencies in the

areas of transacting business, record keeping and housekeeping and on the other hand, it has

increased the vulnerability of the systems.

As banks are reaching out to customers through various new channels such as internet banking and

mobile banking, there is an urgent need for banks to put in place a proper mechanism to protect

themselves and their customers. Therefore, there is an imperative need for an appropriate

organisational structure. Moreover, from the legal perspective, there is also a need to protect the

personal data of customer.

IDRBT has dealt with this subject that is very relevant today as it is related to safeguarding the most

significant asset of the banks - financial data.

In this context, the Handbook on Information Security Governance has relevance to the Indian

Banking Sector. This handbook has suggested a model governance structure for banks and practical

guidelines for its implementation.

I am sure this will help in sensitizing banks and serve as a practical handbook for implementing

Information Security Governance.

I congratulate all the members of the Group who have prepared this handbook.

Foreword

Information Security Governancefor the Indian Banking Sector

T HERE has been massive use of Information and Communications Technology (ICT) in the

banking sector in India. Delivery channels have immensely increased the choices offered to the

customer to conduct transactions with ease and convenience. Various wholesale and retail payment

and settlement systems have enabled faster means of moving the money to settle funds among

banks and customers. Banks have been taking up new initiatives for financial inclusion, customer

relationship management, etc., to widen the reach of banking.

The dependence on technology is such that the banking business cannot be thought of in isolation

without technology. The dependence on technology has led to various challenges and issues like

frequent changes or obsolescence, multiplicity and complexity of systems, different types of controls

for different types of technologies/systems, proper alignment with business objectives and

legal/regulatory requirements, dependence on vendors due to outsourcing of IT services, vendor

related concentration risk, segregation of duties, external threats leading to cyber frauds/crime,

higher impact due to intentional or unintentional acts of internal employees, new social engineering

techniques employed to acquire confidential credentials, need for governance processes to

adequately manage technology and information security, need for appreciation of cyber laws and

their impact and to ensure continuity of business processes in the event of major exigencies.

Technology risks not only have a direct impact on a bank as operational risks but can also exacerbate

other risks like credit risks and market risks. Given the increasing reliance of customers on electronic

delivery channels, any security related issues have the potential to undermine public confidence in

the use of e-banking and may lead to reputation risks. Compliance risk is also an outcome in the event

of non-adherence to any regulatory or legal requirements arising out of the use of ICT. These issues

ultimately have the potential to impact the safety and soundness of a banking system and in extreme

cases may lead to systemic crisis.

Corporate Governance constitutes the accountability framework of a bank. Information Technology

(IT) Governance is an integral part of it. It involves leadership support, organizational structure and

processes to ensure that a bank's IT sustains and extends business strategies and objectives.

Effective IT Governance is the responsibility of the Board of Directors and Executive Management.

I thank and congratulate the Members of the Working Group on Information Security Governance for

the Indian Banking Sector and Institute for Development and Research in Banking Technology

(IDRBT) for doing an excellent job in preparing and timely release of this report.

Information Security Governancefor the Indian Banking Sector

I NFORMATION is a key strategic and operating asset for many enterprises and more particularly

for financial services industry. Its reliability, accuracy and availability are critical to achieve

business goals. From a customer perspective privacy and confidentiality needs to be protected.

Compliance with IT Act requires demonstration of reasonable security by banks. With ever increasing

use of electronic channels by customers, information security is becoming complex. The occurrence

of security breach is not if, but when. We need an appropriate information governance structure to

achieve those objectives.

IS Governance is still in infancy both in understanding and practice. It is in this context IDRBT has

attempted to come out with a reference framework. This edition deals with establishing

organizational structure, role and responsibilities of both IT and business divisions.

Threat landscape is fast changing. In terms of threats it is a moving target and in terms of response

management, it is work in progress most of the time.

It is useful to begin by promoting a culture that recognizes the value of information as enterprise

asset. Top managements need to set the tone and security posture by establishing security vision and

strategy.

There are several elements of IT infrastructure like servers, applications, network, data base, end

point security, delivery channels. Each by itself is a specialized function. Security functions, activities

and policies need to be aggregated through appropriate security organizational structure. While

strategy and policy formulations are best dealt with in a centralized model, functions and activities are

best achieved in a federated model.

Security cannot be seen as an exclusive IT function or from operational risk perspective. Information

security transcends IT division's boundaries and particularly functions like compliance, access

rights/services, data privacy, protection and trust revolve around business. IT-Business alignment

would foster shared security vision and strategy. Information security can converge with physical

security as well.

While everyone is responsible for security, it is the CISO who continuously assesses and enforces

compliance.

IDRBT recognizes that there is no unique security organizational structure. The proposed structure is

only a reference point. Banks may adopt and adapt the structure and roles as dictated by the scale

and complexity of business.

I thank the members of the group for their contribution in developing this framework.

Preface

Information Security Governancefor the Indian Banking Sector

4

T HE Financial Sector is getting increasingly interconnected and complex. Acquisition, processing

and use of vast amounts of customer data apart from banks' own business information has

brought to light the vulnerabilities in information systems that can lead to compromise of

confidentiality, integrity and availability of information. This brings into focus the need for effective

Information Security Governance in banks to protect themselves and their customers adequately and

appropriately.

The Guidelines from the RBI Working Group on Information Security, Electronic Banking, Technology

Risk Management and Cyber Frauds have also reiterated the urgency for putting in place a robust

information security framework in banks. This document is a contribution in that direction.

IDRBT has formed the CISO Forum which provides a platform for Information Security professionals

in banks to share their concerns and arrive at actionable programmes. A sub-group of the CISO

Forum has been constituted to outline the contours of Information Security Governance for the Indian

Banking Sector. This sub-group has developed this document to provide a framework for Information

Security Governance that banks can adopt with necessary modifications to suit their specific needs

depending on their size and scale of operations.

“Information security governance is a subset of enterprise governance that provides strategic

direction, ensures that objectives are achieved, manages risks appropriately, uses organisational

resources responsibly, and monitors the success or failure of the enterprise security programme”

- ISACA.

Effective Information Security Governance in Banks calls for a variety of efforts and initiatives across

the entire spectrum of the Organizational Structure. Notable among them are:

Board level direction and active involvement in Information Security

Top Management support for prompt resolution of Information Security Issues

Integration between Business and Information Security

Alignment of Information Security mechanisms with Organizational Goals and Objectives

Information Security planning and assessment of new technologies before deployment.

Ownership and accountability, at all levels – controlling offices as well as field operations – for

planning, implementing, monitoring, reporting on and improving Information Security.

Introduction

InformationSecurity Governance

Information Security Governancefor the Indian Banking Sector

The Critical Success Factors which would facilitate the attainment of satisfactory levels of Information

Security Assurance within the bank are:

Appropriate placement of Information Security within the Organizational Structure

Consistent message and conviction from the Board and the Top Management vis-a-vis

Information security policy perspectives

Adequate and appropriate employee education and awareness on information asset protection

Continuous and consistent enforcement of information security polices and standards

Ability and willingness to justify the cost of Information Security initiatives

Constantly raising the bar with regard to Best Practices and Metrics being adopted in ensuring and

improving Information Security.

This document focusses on the managerial aspects of Information Security and not on the technical

side. And to be precise, this is an effort to provide an effective Information Security Governance

Structure for the Indian Banking Sector. This document would also facilitate compliance with

Information Security Management Systems (ISMS) - ISO/IEC 27001, especially, the Control

Objectives relating to Internal Organization, as given below:

To manage information security within the organization.

Management shall actively support security within the organization through clear direction,

demonstrated commitment, explicit assignment, and acknowledgment of information security

responsibilities.

Information security activities shall be co- ordinated by representatives from different parts

of the organization with relevant roles and job functions [Overall coordination shall be with

Information Security Group (ISG) headed by CISO. At the organization level the responsibility is with

CISO].

All information security responsibilities shall be clearly defined.

There must be a robust governance framework in place to ensure top management involvement

and oversight in Information Security on a regular basis.

The Bank must have a comprehensive information security policy covering all aspects of security

domains.

Information security must be a dynamic and ongoing process aimed at continuous improvement.

The principle of Defence in Depth may be adopted to protect critical assets by providing them with

a layered security.

Information security must focus on business and provide value and quality to its stakeholders.

Information security risks and costs are the joint responsibility of Business and IT.

Information security should be part of everyone's responsibility and hence to be embedded in

staff roles and job descriptions.

Information security function must have a dedicated, skilled, experienced & adequately staffed

team.

All IT and Business Changes, including new initiatives must be subjected to a thorough and robust

risk management process with a clear focus on protecting classified information and critical

business applications.

Information security must be part of the design architecture of any product and service.

Information security risk management must be based on Business Impact Assessment and

evaluate current and future threats and develop a long term roadmap for effective protection of

all information assets.

Information Security Programme must encompass the Business Continuity Management and

Disaster Recovery Plans of the Bank.

Information security team must act in a professional and ethical manner to foster a positive

security culture within the Bank.

The Information Security Committee must have an effective oversight to review and monitor the

Information Security Programme of the Bank.

Information security function must provide timely and accurate metrics on performance with

regard to Information Security.

Information security governance must comply with relevant legal and regulatory requirements.

Policies and controls must account for business context.

Information Security is not a practice within business and is an integral part of business and as

such a corporate level function.

The Information Security Committee at the top management level should be responsible for overall

governance of the Information Security Programme of the Bank and will report to the Board.

A Working Group on Information Security should be set up in the Bank, which shall have representatives

from business, operations, audit, IT, vigilance, physical security / admin etc. This Working Group should

meet on a regular basis to discuss implementation issues pertaining to information security.

The Information Security policies shall be approved by the Board and cover the three important aspects

of information viz. People, Process and Technology.

The Information Security Risk Management shall cover risk identification, assessment, remediation and

acceptance of residual risk.

Education and Awareness efforts shall be continued on a regular basis to keep the rank and file abreast

of their roles and responsibilities vis-à-vis the expectations from the Information Security Policy.

Information Security should be a regular component in training programmes offered within the Bank.

This may be supplemented by online education in the form of snippets, write-ups for paced-learning,

tests and quizzes.

Customer Education on Information Security, especially in Electronic Banking and delivery channels,

must be accorded due prominence. Regular, multi-pronged efforts must be made to inculcate best

practices and common minimum standards among customers to provide security to their electronic

transactions. Appropriate tools and channels may be utilized for this purpose.

Security Implications of the Business Continuity and Disaster Recovery Policies must be approved and

periodically reviewed by the Board.

Information Security function must be adequately staffed, trained, equipped and motivated to maintain

the Bank's Security Posture at expected levels.

Banks information system shall be regularly subjected to regular information security testing

commensurate with their exposure (criticality and threats) level.

For effective implementation of information security policies at the grass root level, each department or

functional division should identify an official who would be responsible for driving information security

agenda for that respective unit.

The information security program should have comprehensive and detailed metrics which will be

presented to the Information Security Committee.

The information security programme (design, implementation & execution) should be reviewed and

tested by the Bank's IT audit. The IT audit strategy should be aligned with information security strategy

for the areas of implementation and execution.

The information security enforcement strategy should be comprehensive and should cover the

complete lifecycle of Data, Applications, Technology, Infrastructure, People, Products and Services.

The Information security programme shall be tested on an ongoing basis for compliance to applicable

regulations.

The Information security programme shall be benchmarked with the industry level and global best

practices.

Banks should not only have security strategy but also ability to execute strategy and ability to measure

execution.
