ISO/IEC 27001, 2005 is a specification which helps to provide information security management system (ISMS). An ISMS is a framework of the policies and the procedures that includes all the legal, physical and the technical controls which are involved in an organization’s information risk management processes. This, however, has been developed in order to “provide a model for establishing, implementing, operating, maintaining, monitoring, reviewing, and improving an information security management system.”
The reasons as to why ISO 27001 should be considered are:-
- It is Required in tender documents:-
The organizations have security breaches and the organizations that are larger are taking its security seriously. These organizations for its security are implementing standards and are then pushing their requirements down onto the suppliers and are forcing them to meet their standards. These are often in the tender documents from financial organizations, retailers, and government departments. In some cases when the organization does not meet these standards it is not able to win in business.
- External Audit Requirements:-
Most of the Organisations are audited for many reasons and some of these are directly from its customers. These customers who do the auditing have requirements and they expect their suppliers to follow these. An unprepared company is at a risk since it has to go through significant turmoil, time and cost to meet these customer requirements. ISO 27001 helps these organizations to meet a level which satisfies these audits.
- Control risk within the organization:-
Security risk becomes difficult when the organization has to quantify within the organization, and ISO 27001 ensures that an organization manages the risk in a structured and an appropriate manner to the business.
- Major Incidents:-
Many organizations suffer major security incidents and they often react incorrectly as well as also suffer financial loss. Avoiding these incidents helps to maintain confidence with customers and the other organizations. ISO 27001 helps to manage the incidents, and since it is aware of the risks of an organization and in many cases it also prevents the incidents occurring in the first place.
- Understand the weaknesses of the business:-
The Businesses have areas of strength in relation to security and they also have weaknesses. Understanding and mitigating these weaknesses allow the organization to have more control over its activities and also helps to put controls in the place to strengthen those weaknesses.
- It helps to Improve the Process:-
The inconsistently applied processes cause security risks and potential breaches these processes become inefficient and it also becomes costly to maintain. Putting in place the standard and the appropriate processes means the that activities are repeatable, manageable and cost-effective within the organization.
- It helps to maintain existing business:-
The Clients often tend to change their requirements over time. When they change these requirements they often increase the security requirements. Organizations which achieve this ISO 27001 certification are significantly less affected by these changes.
- Implement continuous improvement:-
A Built into the ISO 27001 management system is a continuous improvement cycle which involves actions like Plan, Do Check, Act. However, following this cycle helps an organization to continuously improve their security practices and they can also apply this to the wider business.
- It helps to understand the key assets of the business:-
One of the core requirements of ISO 27001 is that it helps to ensure that an organization manages its key assets in a way which is appropriate to the business. Many organizations, however, are not clear on what their key assets are and how best to protect them and this provides a framework for managing them.
- It also helps to Implement consistent control and process:-
ISO 27002 contains a control framework based on that a baseline can be set for the organization’s assets ensuring the minimum level of control is in place. This applies to the processes as well as the assets and allows the activities to be repeatable and maintainable.
- Worry less:-
In all the organizations the information held is of critical importance to them and their clients. ISO 27001 allows the organization to put a framework in place for managing this information. It’s not fully prescriptive to allow security which is to be implemented that is appropriate to the business. However, it forces control which is to be improved within the business thus allowing the organization to worry less.
