• There are mainly three sources for security requirements like assessment of risks to the organization; legal, statutory, regulatory, contractual requirements; and finally the set of principles, objectives, and requirements for information processing developed by the organization in order to support its operations

Implementation process of Information Security Management System

The basic security requirements related to any organization, large, medium or small, are usually derived from three sources. First is the unique set of security risks to the assets of an organization's information systems. These risks are a combination of the threats and vulnerabilities to the assets and the potential impact of these security risks on the business. The second source of security requirements are those statutory and contractual requirements that an organization, its trading partners, contractors and service providers have to satisfy. Lastly, the third source of security requirements are those principles, objectives and requirements for information security that an organization has developed to support its business operations. These could be derived from corporate directives and /or international best practices on Information Security Management such as British Standard ISO 27001 or International Standard ISO 17799.

To establish the management framework for Information Security Management System, here is a recommended route.

• First you need to define the scope of the Information Security Management System. An Information Security Management System can cover all or part of an organization.

• Next you need to also define and document Security/ Information Security Management System Policy. Here you need to focus on various issues such as: Why is information security important to you? Is there a particular threat, or other worries that concern you? What do you want to achieve, for example in terms of confidentiality, integrity and availability? What do you believe is an acceptable level of risk? Are there any constraints, such as laws and regulations, or particular ways in which you wish to do things?. There can be other issues too.

• Also plan and carry out Risk assessment.

• You need to develop Risk treatment plan.

• Select control objectives and controls with the help of ISO 27001 where a detailed list of candidate control objectives and controls are provided.

• You must also prepare a Statement of Applicability (SOA) where you need to describe the control objectives and controls that are relevant and applicable to the organization's ISMS, based on the results and conclusions of Risk Assessment and risk treatment processes.

• Now obtain management approval of the proposed residual risks and authorization to implement and operate the Information Security Management System.

To carry out Information Security Management System in the right way, you need to hire experts undergone some good information security course from some reputed institution. In fact, there are many institutions in the market that offer information security training courses to meet the demand of the market.
