Risk management is unquestionably the most challenging aspect of implementing the ISO 27001 standard, but it is also the most crucial phase of any information security project since it lays the foundations for information security in the organization. Risk treatment and risk assessment are the two fundamental components of risk management.

An organization should identify information security threats, as well as their probability and effect, during the process of risk assessment. To put it simply, the organization must be aware of every informational issue that could arise, as well as the possibility that it will happen and any potential repercussions. The goal of risk treatment is to identify the security controls (also known as safeguards) that are required to prevent those potential occurrences; this process of control selection is known as risk treatment and in ISO 27001, controls are selected from Annex A. Even though risk management in ISO 27001 is a difficult task, it is frequently unnecessarily obscured. The following six fundamental stages will help you understand what to do:

ISO 27001 risk assessment methodology: ...
... This is the first phase of the journey through ISO 27001's risk management process. The largest issue with risk assessment is when different areas of the business carry out it in different ways, therefore it's crucial to define the guidelines for how organizations are going to conduct risk management if it's important for the entire organization to do it the same way. As a result, the company must decide if they need a qualitative or quantitative risk assessment, what scales to use for the qualitative evaluation, what the acceptable threshold of risk is, etc.

Risk assessment implementation: Once you are aware of the rules, an organization can begin identifying the potential issues that might arise for you. The organization must first make a list of all their assets, then threats and vulnerabilities related to those assets, then evaluate the impact and likelihood of each combination of assets/threats/vulnerabilities, followed by a calculation of the level of risk.

Risk treatment implementation: Naturally, not all risks are equal; organizations must concentrate on the most significant hazards, the so-called "unacceptable risks." There are four different ways available to handle (i.e., mitigate) each unacceptable risk when putting ISO 27001's risk treatment into practice.

Risk Assessment and Treatment Report: In contrast to the other steps, this one requires you to thoroughly document everything you've done so far. The organization will probably want to review these results for yourself in a year or two, so it's not just for the auditors.
Statement of Applicability: Based on the outcomes of the risk treatment in ISO 27001, it's necessary to explain all the controls that were installed, why your company adopted them, and how. This document genuinely displays the security profile of your business. The ISO 27001 documents is crucial because the certification auditor will rely heavily on it when conducting the audit.

Risk Treatment Plan: The transition from theory to practice must be made at this stage. To be honest, this entire risk management task has been entirely theoretical up until this point. It is now time to demonstrate actual results.

To specify precisely who will apply each control, when, how much money will be allocated, etc., is the goal of the risk treatment plan. I'd rather name this document an "Implementation Plan" or "Action Plan," but let's utilize the terms found in ISO 27001. The route to having a crystal-clear understanding of what you need to implement began with you having no idea how to set up your information security. The key takeaway is that ISO 27001 requires organization to proceed in a methodical manner.

For example, an organization can include a detailed description in the ISO 27001:2022 Manual of the entire risk assessment process (as per clause 6.1.2). Unfortunately, this is where a lot of companies make their first, most critical error: they start implementing risk assessment without the methodology, or, to put it another way, without any established guidelines for how to do it. There are numerous misunderstandings about what a risk assessment should look like, but in truth, ISO 27001:2022 criteria are not tough - here is what clause 6.1.2 requires:

• Describe how to identify threats that could result in the loss of your information's confidentiality, integrity, and/or availability.
• Define the process for locating risk owners.
• Define the parameters for evaluating the risk's likelihood and its effects.
• Specify the method for calculating risk.
• Establish the criteria for accepting risks.

Therefore, organizations must specify these five components in order to function effectively. Anything less won't do, but more importantly, anything more is unnecessary, so keep things simple.
