What Is Information Security Management System?

Businesses of all sizes deal with large amounts of information every day. These organizations take this data to be a competitive advantage over other businesses in the same industry. That’s why these businesses and organizations have policies and procedures put in place to manage their sensitive data systematically.

The purpose of these policies and procedures is to limit the effects of a security breach by reducing risks. This set of policies and procedures is what is known as information security management systems (ISMS).

ISMS normally processes data, and technology and addresses employee behavior. Organizations can either decide to implement the ISMS in a specific type of data or apply it comprehensively to become a part of the company’s future.

ISMS is created using ISO 27001 specifications. The specifications do not order appropriate actions, but have suggestions for internal audits, documentation, corrective and preventive actions and continuous improvements.

Principles of ISMS

The implementation of ISMS varies from business to business. However, there are basic principles that all information security management systems must follow in order to protect an organization’s sensitive data effectively. Some of these principles are highlighted below, and they can assist you in achieving ISO/IEC 27001 certification.

The first step towards successful implementation of ISMS is making the management understand the need for information security. It is hard to maintain certified ISMS if there are no people to implement, oversee and maintain the system.

Businesses must analyze the security needs for each information asset for the ISMS to be effective. An effective ISMS helps an organization to apply the necessary measures to ensure that their information is safe.

They should understand those information assets require different controls. Information comes in different types, so do the controls.

ISMS implementation is a continuous process, not a fixed project. An ISMS must be able to continuously grow and evolve to adapt to ever occurring technical changes for it to protect your organization’s information.

Therefore, there must be a continuous re-assessment of the ISMS. An organization can know whether its data is protected or not by testing the information security management system regularly. Those are just a few principles of the ISMS.

Information security is a management function

Usually, there are numerous technical aspects of developing an ISMS, but, the management is responsible for a large portion of it. People with regular access or control to critical information are amongst the weakest links in information security.

Thus, for an ISMS to be successful, management must develop policies to prevent employees from misusing sensitive data. For the policies to be effective, they must be supported by an oversight of the management.

The organization should also change the culture of the entire organization to show that they value information security. This is a very critical issue in the implementation of ISMS though it is not easy.

Information security management is a process

ISMS adapts to evolving technology, and new organizational information just like businesses do adapt to changing business environments. ISO/IEC 27001 checks the ISMS plans regularly to ensure it adapts to these changes.

Dynamic issues surrounding ISMS

Changing dynamics for security requirement in an organization

Rapid technological changes are not only posing as challenges to businesses, but also as security concerns. Every technological change renders existing security measures obsolete thus creating new vulnerabilities. Thus, the ISMS should always keep the system up-to-date to manage the vulnerabilities.

Externalities caused by a security system

Externalities can either be positive or negative. These are the economic concepts of effects brought about by parties involved in a transaction indirectly. An ISMS implemented in a business can also cause externalities for other systems. These externalities cannot be determined before the deployment thus they are uncertain.
