ISO 27001: ISMS Policy

by Swapnil Wale

Adopting an ISMS is a significant decision for any organization. Costs and effort to implement and maintain ISMS are considerable, and benefits may become apparent. Organizations must carefully weigh the costs and benefits before adopting ISO 27001. It is also important to remember that ISO 27001 is not a requirement. Organizations do not need to be certified to implement an ISMS. Many organizations opt to become certified to show their commitment to data security and market their products to potential clients.

Certification vs Self-Declaration To Get ISO 27001 Certified

Organizations can only implement ISMSs if they obtain certification. Many organizations seek certification to show their commitment to data security and market their products or services. ISO 27001 certification can be achieved in two ways:

    • Self-declaration (also called first-party certificate) is a method by which an organization certifies that its ISMS complies with all ISO 27001. This is a less common approach because it can be challenging to convince customers and stakeholders that an organization's claims about its ISMS are credible.
    • Third-party certification is a process where an independent certification body evaluates the ISMS of the organization against ISO 27001. This is the most typical approach, and it is more credible than self-declaration. The certification bodies must be accredited through a national organization, like ANAB (in the United States).

ISMS Policy: Its Importance

  • Security- Organizations face daily security risks. These risks may come from external sources such as hackers or internal sources such as employees. These security risks can compromise the safety of data and systems in an organization. ISMS policies can mitigate these risks for businesses by setting clear guidelines on how to handle and protect data. Companies can use these policies to protect their data from internal and external threats.
  • Compliance- ISMS policies help businesses stay compliant with laws and regulations, as well as protect their data. As the focus on data privacy has increased, many laws and regulations have been passed that require businesses to take steps to protect customer information. ISMS policies can help businesses comply with laws and regulations by defining the steps to protect data. This includes defining how data is stored, transmitted, and destroyed. Businesses can ensure compliance with laws and regulations by following an ISMS.
  • Implementation- Businesses should consider their specific organizational needs when implementing ISMS policies. The policy should be tailored according to the size, type, and amount of data the organization stores and processes. The policy should also be regularly reviewed to ensure it is practical and up-to-date.
    • Improve efficiency- ISMS policies help businesses to improve their efficiency. They can do this by helping them comply with regulations and protecting data. If everyone in the organization adheres to the same guidelines, this can streamline processes and reduce errors.

    ISO 27001 Guidelines for Implementing ISMS Policy

    ISO27001 is a standard that provides a framework to create an Information Security Management System. The ISMS is an approach that uses a systematic strategy to manage sensitive information to keep it secure.

    1. Setting up the ISMS Policy

    The policy should be developed at the highest management level, taking into account the business objectives of the company, its risk appetite, and any legal or regulatory requirements. It is essential to review and update the policy regularly.


    2. How to perform a risk assessment

    It is essential to conduct a risk assessment to determine which assets must be protected, the threats to which they are vulnerable, and the controls that can be used to reduce those risks. Regular assessments are necessary to stay abreast of changes in the business world.

    3. Develop and implement controls

    Controls (policies and procedures, etc.), based on the results of risk assessments, need to be developed and implemented to reduce identified risks to an acceptable level. To reduce identified risks to an acceptable level, controls (policies, procedures, etc.) must be developed and implemented based on the results of the risk assessment. The rules must also be updated and reviewed regularly.

    4. ISMS Monitoring and Review

    It is essential to monitor the ISMS constantly to ensure it works properly and has adequate controls. It should be reviewed at least once a year to make sure it's still up-to-date and relevant.

    What should you include in your ISMS policy?

    • Purpose: Your policy's purpose and priorities should be clearly stated. It may be aligned with your company's objectives and plans. Are you designing this to protect the information of your clients? Are you trying to protect against security breaches? Knowing the purpose of the policy will help you to determine the security procedures that are needed for your organization.
    • Roles and responsibilities: The policy should define the roles and responsibilities of the different individuals and groups in the organization who are responsible for securing information. The policy, for example, should identify the person responsible for the development and maintenance of the organization's policies and procedures. The policy should also identify the individuals who are responsible for monitoring and implementing the security controls of the organization.
    • Policy Framework: The third step involves developing a policy framework that will be used for creating and implementing specific information security policies. The ISMS policy frame is based on the ISO 27001 standard of information security management. It guides the planning, implementation, operation, monitoring, and improvement of an ISMS.
    • Communication of ISMS Policy: This is a way for an organization to effectively communicate its ISMS policies with employees, contractors, and other interested parties. This process begins with the creation of a clear and concise policy statement that is distributed to all relevant stakeholders. The communication process for ISMS should be designed so that all stakeholders understand and comply with the ISMS policy. The process should also be reviewed periodically to remain appropriate and effective.
