What is ISO 27001?
ISO 27001 is a popular certification that can help Organizations manage their information security risks better. While the standard has been around for decades, it’s becoming more in demand as more Organizations are seeing the benefits of ISO 27001 certification. In this article, we’ll look at what ISO 27001 is, what its controls are and why ISO 27001 Controls is necessary.
ISO 27001 is an International Standard for Information Security Management. It provides guidelines for establishing, implementing and maintaining an Information Security Management System [ISMS].
It’s important to note that ISO 27001 controls is not only important when it comes to data protection and privacy. The standard also includes guidelines on how to protect the following:
- Confidentiality: Information should be protected from unauthorized disclosure; for example, by keeping documents locked up or marking them “confidential.”
- Integrity: There should be no unauthorized changes made to the data. For example, no one can change bank account numbers while they are in transit between two financial institutions.
- Availability: Data should be accessible when needed.
The benefits of ISO 27001
What are the benefits of ISO 27001?
- Increased security: This is one of the most important benefits of ISO 27001, as it helps you to protect against data loss and other security threats.
- Reduced risk: The policies and procedures in place will also help reduce your risks, which is great for both your company and its customers.
- Improved efficiency: Having implemented an IT system that meets all of these requirements means you should be able to operate more efficiently than before, saving time and money on things like training staff members who use the system regularly or replacing equipment that isn’t up to scratch with something new that complies with these standards.
- Improved customer satisfaction levels through greater transparency about how information is stored online or offline within a business structure: This allows customers more confidence in doing business with companies who abide by such strict standards regarding transparency (as well as privacy).
ISO 27001 Controls: What are the primary goals of the controls described in ISO 27001 Annex A?
The primary goals of the controls described in ISO 27001 Annex A are to:
- Protect the Confidentiality, Integrity and Availability of information assets.
- Manage risk.
- Ensure compliance.
- Provide a framework for Information Security Management.
Who is in charge of carrying out Annex A controls?
The ISO 27001 Lead Auditor is responsible for assessing the effectiveness of Annex A Controls. This includes performing periodic evaluations, reviewing security-related documentation and carrying out other procedures as prescribed by the Information Security Management System [ISMS].
The Organization’s management should perform regular reviews of ISMS activities, being aware that its employees could be affected by social engineering attacks or malware infections. It should also ensure that the Information Security Officer is fulfilling his/her role in accordance with Organizational policies and standards such as those suggested by ISO 27001:2013.
Internal Auditors need to identify potential risks associated with data processing activities and report their findings to relevant parties within an Organization so that they can be addressed accordingly. They also need to monitor any changes made to how data is processed (e.g., through new business practices) in order to identify whether these affect existing controls or introduce new ones that may require additional monitoring efforts going forward.
External auditors are tasked with ensuring compliance with all applicable regulations/policies governing privacy protection requirements among Organizations who collect personal data about individuals residing within countries where such laws exist; this includes conducting audits on businesses’ various IT systems if necessary (e.g., web applications).
Using the ISO 27001 Controls
- How to Use the ISO 27001 Controls
Like any other quality standard, ISO 27001 is designed to help you understand what you need to do and how it should be done. It gives you a framework to make decisions about your security systems, so that you can improve them over time. But it doesn’t tell you everything—you still have to develop your own policies and procedures based on the requirements of your business.
- Which ISO 27001 Controls to Use
Each of ISO 27001 controls includes a description of what its purpose is, along with an indication of its scope (which parts of your Organization are affected), its applicability (who has responsibility for implementing it), and how effective it is as an aid toward improving security practices within your Organization.
- Implementing ISO 27001 Controls
In order for controls like these to work effectively at providing adequate protection against risks faced by Organizations or individuals with whom they interact online, they must be implemented in accordance with their intended purpose while also considering other factors such as cost effectiveness versus effectiveness; ease of use; complexity level required in order for personnel involved in management activities related to perform effectively; potential impact on productivity levels if any changes are made before implementation begins versus after completion so that everyone knows exactly what steps need taking ahead -to-timely completion and so on.
What are the 14 domains of ISO 27001?
The fourteen (14) domains of ISO 27001 are:
- Information security policies: This domain refers to the systems and procedures that are in place to manage and protect information assets. It covers policies, standards, procedures and guidelines that are used by an Organization to ensure security compliance. These concepts include access control, change management, disaster recovery plans, emergency response plans and incident response capability.
- Organization of information security: This domain refers to the management of information security within an Organization. It covers the structure, roles and responsibilities of people who are responsible for managing information security. This domain also includes how an Organization identifies its assets and classifies them based on their sensitivity and value, as well as how it determines the risk associated with each asset.
- Human resource security: This domain deals with the effective management of human resources within an Organization. It also focuses on how an Organization identifies and trains its staff, as well as its policies concerning recruitment, retention and termination.
- Asset management: This domain focuses on how an Organization manages its assets. It includes understanding which assets need to be protected and classifying them based on their value and sensitivity, as well as managing access to these assets.
- Access control: This domain focuses on controlling access to an Organization’s assets. It includes understanding how an Organization defines its policies and standards, as well as the controls that it puts in place to enforce these policies and standards.
- Cryptography: This domain focuses on how an Organization handles and protects its sensitive data. It includes understanding the encryption standards and algorithms that it uses, as well as its policies concerning access to these assets.
- Physical and environmental security: This domain focuses on the physical and environmental security of an Organization’s assets, including its facilities and data centers. It includes understanding how an Organization protects these assets from natural disasters, as well as man-made threats like theft or sabotage.

It also focuses on understanding how to ensure that the Organization’s information security measures can support compliance efforts in case of an incident.
Finding the ISO 27001 Controls You Should Use
Control is an activity in place to help you achieve your goals and it’s important that the controls that are implemented are specific to your Organization. It’s best if they are documented and reviewed regularly by all stakeholders of the process.
ISO 27001 controls are a good place to start when finding the right set of processes for your Organization, but it is recommended to use them as a reference point rather than copying them entirely. Your business may have different tools or methods at its disposal that would work better than those defined by ISO standards or even another control framework altogether—but only if they’re implemented correctly!
What Will ISO 27001:2022 Bring?
The new standard will include the following:
- New control domains (e.g., physical security, people security) and controls (e.g., data classification, data loss prevention).
- Changes to existing controls. For example, in 2024, password policies must be changed because they are no longer considered good practice; this will require an assessment of whether alternative methods such as biometrics or multi-factor authentication are viable solutions.
- A new risk assessment process that includes identifying impact levels and likelihoods within each control domain before considering risk treatment options available in the Control Assessment Matrix (CAM). The CAM has been simplified from the previous version so it can be more easily used by businesses with limited IT resources or experience with IT security issues – in other words, most small businesses!
- New requirements for conducting formal vulnerability assessments in certain circumstances as well as re-evaluating a company’s overall cyber resilience every three years on average using either an external party or internal staff members who have been trained how to do so properly will also be part of the new regulations.
The International Organisation for Standardisation [ISO] has published a new version of the ISO 27001 standard in 2022. This new version will be more comprehensive than its predecessor, covering more controls and being easier to use.
Conclusion
We hope that this article has given you a better understanding of ISO 27001 controls and the importance of implementing the controls described in it. As the world becomes more connected, it is increasingly important for companies to ensure their information security at all times.
