Introduction

The ISO 27001 standard was published in October 2005, essentiallyreplacing the old BS7799-2 standard. It is the specification for an ISMS, anInformation Security Management System

The objective of the standard itself is to "provide a model for establishing,

implementing, operating, monitoring, reviewing, maintaining, andimproving an Information Security Management System". Regarding itsadoption, this should be a strategic decision. Further, "The design andimplementation of an organization's ISMS is influenced by their needs andobjectives, security requirements, the process employed and the size andstructure of the organization".

The standard defines its 'process approach' as "The application of a systemof processes within an organization, together with the identification andinteractions of these processes, and their management". Deming's PDCAcycle.

Information

'Information is an asset which, like other important

business assets, has value to an organization and

consequently needs to be suitably protected

BS ISO 27002:2005

Why Information Security

It ensures Business continuity

Reduces and prevents damage to the organisation

Ensures preservation of confidentiality, integrity and

availability of information and also authenticity,accountability, non-repudation, and reliabilityenhanced.

Increases awareness among key staff and stake holders

Identify, analyse and treat risks. Identify threats and vulnerabilities

Minimizes financial loss

Information Security Management

System

ISMS is the part of overall management system

based on business risk approach, to establish,

implement, operate, monitor, review, maintain

and improve information security.

It is a management process with 3 key

components.

Confidentiality (Authorised access to information)

Integrity (Accurate and complete)

Availability (Authorised access when required)



7/18

Implications of security breaches

Reputation loss

Financial loss

Intellectual property loss

Legislative Breaches leading to legal actions

Loss of customer confidence

Business interruption costs



8/18

Features of ISO 27001

Plan, Do, Check, Act (PDCA) Process Model

Process Based Approach

Stress on Continual Process Improvements

Scope covers Information Security not only IT Security

Covers People, Process and Technology

Some organisations will opt to implement the standard for a better management

and security controls and to prove their commitment towards their

stakeholders and confirm that they have the best practices in place.

Some organisations opt to go for certification in case they have a customer who

outsources a process to the organisation and insist that the outsourced

process is compliant with the standard.

PDCA Cycle



10/18

PDCA

Plan (establishing the ISMS)Establish the policy, the ISMS objectives,processes and procedures related to risk management and theimprovement of information security to provide results in line with theglobal policies and objectives of the organization.

Do (implementing and workings of the ISMS)Implement and exploit theISMS policy, controls, processes and procedures.

Check (monitoring and review of the ISMS)Assess and, if applicable,measure the performances of the processes against the policy, objectivesand practical experience and report results to management for review

Act (update and improvement of the ISMS)Undertake corrective andpreventive actions, on the basis of the results of the ISMS internal auditand management review, or other relevant information to continuallyimprove the said system.



11/18

Short term planning Prepare a statement of applicability (SOA)

Request for management approval and commitment to the implementation ofISMS and approval on residual risks. (Define a budget and a feasibility plan)

Formulate and implement a risk treatment plan.

Training and initiate the project with a small scope

Define a team (IT, HR, Management, Audit, QA) and prepare a project plan as perthe SOA.

Implement and operate the ISMS. Measure effectiveness of control.

Review risk assessment at planned intervals.

Internal ISMS audit and management review

Record actions and events

Check and monitor the people, processes and technologies.

Maintain and improve.

Management review.

Implement identified improvements

Take preventive and corrective actions

Communicate actions and improvements

Ensure the improvements achieve intended objectives.



12/18

Short term benefits

A well document process and abides to

regulations.

Increases awareness among staff and higher

management.

Enhances information security

Helps to identify new risks and vulnerabilities

when reviewing the processes.

A clear audit scope.



13/18

Long Term Planning

Define a budget and a feasibility plan

Staff training and team building

Effective communication and a project team.

Internal Audits

Management Review Corrective and preventive actions

Identify a certifying body

Pre certification audit

Certification Audit Post certification: Semi annual review (depending on the

ISMS requirement)

Continual improvements and review.



14/18

Long Term benefits

Recognition and ISO 27001 certification

A well defined security control for People,processes and Technology.

Effective communication and awareness. The certification can be used as a marketing item.

Provides assurance to Stakeholders and

customersIt enhances information security

Ensures that the organisation is compliant.

Banks who have implemented ISO

27001

Burgan Bank, among the youngest and most dynamic

banks in Kuwait (2010)

Yes Bank (2010)

Cairo Amman Bank (2012) Affin Investment Bank, Malaysia (2011)

Conclusion

The ISMS ISO 27001 provides a standard to organisation tosecure their organisation and is highly recommended tofinancial institutions.

I will advise the bank to consider this internationalstandard to enhance the current setups.

The very important part of this standard is that it requiresmanagement commitment and not handled only at IT level.

The Project management organisation also provides paperson implementation of ISO 27001.

The cost of the project will vary on the scope and anorganisation can chose the system and process they will liketo certify.
