Five Steps to an Effective ISO 27001 Risk Assessment

Risk assessment is a critical step in your ISO 27001 certification journey. An organization-wide risk assessment, in fact, is the central focus of ISO 27001. The information security standard helps to protect an organization’s information assets by identifying the risks and protecting them by deploying relevant security controls and measures.

In this article, we highlight the main steps to an effective ISO 27001 risk assessment and discuss the best practices involved in going about this critical step. And don’t miss our ‘quick and dirty’ cheat sheet on risk assessment at the end of the article.

What is ISO 27001 risk assessment?

The ISO 27001 risk assessment is a systematic process by which an organization identifies its information security risks, their likelihood, and their impact, so as to implement plans to mitigate them. It follows the setting up of a robust and cost-effective Information Security Management System (ISMS).

The entire process is complex and requires a detailed and integrated approach to risk management – from risk identification to risk assessment, and eventually executing a risk treatment plan to mitigate the risks.

Why do organizations need to perform ISO 27001 risk assessment?

ISO 27001 advocates for robust information security policies and procedures and risk assessment is a crucial part of this process. ISO 27001 risk assessment helps identify the current threats and vulnerabilities that can be exploited by malicious actors and compromise the safety of information assets. Based on the risk assessment, the organization can prioritize the implementation of security measures and ensure ongoing improvement.

ISO 27001 risk assessment is a proactive security measure that enables the organization to make well-informed decisions.It minimizes the costs of sudden security incidents  and reduces the chances of business operations disruption. It is additionally a strategic imperative to expedite the certification process and shorten the sales cycle.

How to perform ISO 27001 risk assessment

ISO risk assessment is subjective; no two organizations can have identical risks and assessments. It is therefore crucial to identify information security risks applicable to the organization and determine corrective actions based on risk profile.

Here is the five step procedure to perform ISO 27001 risk assessment for your organization:

1. Identify the risks, threats, and vulnerabilities

Identification of assets: Make a list of the information assets across your organization. These would include your software, hardware, databases, and intellectual property, to name a few. 

Assessing the risks attached: Once you have a comprehensive asset list, identify the risks attached to each asset – risks that could impact the confidentiality, integrity, and availability of each listed information asset. Your threats and vulnerabilities could range from unauthorized access to your database to embezzlement and espionage to inadequate data backup, and password management, to name a few. 

How Sprinto can help?

Integrate Sprinto with your cloud stack and the platform will automatically identify and classify risks based on category and severity.

Sprinto lets you assign risk owners and sends automatic alerts for remediation actions to the right individuals.

2. Assigning owners to the identified risks

Often overlooked, this is an essential step in determining the success of your organization’s risk assessment exercise. For every risk, assign risk owners who would be in charge of monitoring the risk, and eventually implementing the risk treatment plans. 

3. Analyse the risks, their impact and the likelihood of occurrence

ISO 27001 doesn’t define any specific way to analyze and score the risks. It is, therefore, essential to determine an organization-wide standardized approach for the same. Remember, you will base your risk analysis on this pre-defined approach.

Once you have identified and defined your risk universe, the next step is to analyze the identified risks by assigning a likelihood of occurrence and ranking its potential impact on a scale of 1-10 (10 being the highest impact). You could also rank them Low-Medium-High.

4. Calculate the impact of risks

To calculate the impact of the risks, it is a good step to categorize them first. Depending on the nature of your business, your risk categories could be financial, legal, regulatory, and your reputation, to name a few. While rating the impact, you must also consider factors such as how fast the impact will be felt and the likelihood of its occurrence. 

The scores you assign (from 1-10 or low-medium-high) will help you design and prioritize your risk treatment process.

5. Deploy risk mitigation and treatment plan 

Now that you have analyzed the risks and assigned an impact to them, the next step is to define and design a risk treatment plan around them. Doing this is a crucial step, and you must maintain comprehensive documentation of the same.

The risk treatment plan, in short, documents your responses to the threats, vulnerabilities and risks you have identified in your risk assessment exercise. Know that this piece of document is critical to your ISO 27001 certification. Your external auditor will go over it in detail during your ISO 27001 certification audit and the subsequent periodical audits.

Before we dive into your risk responses, it’s essential to define the risk acceptance criteria – what are acceptable risks for your organization? This benchmark would help you design an appropriate risk treatment plan. The ISO 27001 standard lines up four possible risk treatment options. They are:

Treat the risk

If the risk score is above what’s acceptable, you can reduce its impact or likelihood by deploying the security controls as outlined in the ISO 27001 controls in Annex A. Security awareness training, access control, penetration testing, and vendor risk analysis are some of the ways you can treat risks.

Avoid the risk

Another response to the identified risk is to look for ways for avoiding the risk altogether. If the risk-return matrix is lopsided, you can choose to avoid the risk in totality.  For instance, if you are a remote-only organization, you can avoid the risk of maintaining the physical security of your production infrastructure or data centers.

Transfer the risk

Where feasible, you could modify the risk by transferring it to a third party. You could do this by contracting vendors, outsourcing a particular job function, or buying insurance, for instance. 

Accept the risk 

The objective of your risk treatment plan is to bring the risk levels of your information assets, wherever possible, to an acceptable level. Remember, you can’t eliminate all your risks. You can devise a detailed plan on what should be done in the event of a ‘risky eventuality’. These include data breaches, cybersecurity attacks and other such incidents that risk the security of your data. Your risk treatment plan should include well-thought incident response and incident management.

Sprinto suggests you the right risk response strategy and you can accept, transfer or reject risk as per preferences.

Risk treatment plan and Statement of Applicability

Your Risk Treatment Plan and Statement of Applicability are two crucial documents in your ISO 27001 assessment journey. 

Clause 6.1.3 of the ISO 27001 Standard states that an SOA must contain the following:

• List of controls identified as a response to the identified risks
• An explanation for the choice of controls, how they have been implemented, and reasons for the omission of controls, where applicable)

A Statement of Applicability outlines whether each of the controls defined within Annex A of the ISO 27001 standard will be applied or not based on your Risk Treatment Plan. For each risk, you must evaluate the options for treatment.

For instance, applying controls, accepting, avoiding or transferring risks. The SOA must comprise the actions performed based on the selected option. Again, management approval with documentation is needed for each situation where risks are accepted.

ISO 27001 Risk Assessment Examples

The risks vary depending on the industry and other factors. However, here is what a risk assessment table looks like in general. Let us see some examples of ISO 27001 risk assessment.

S. No.	Threat	Vulnerability	Risk Impact (Out of 10)	Mitigation
1	Malware, ransomware, and viruses	Lack of antivirus program and weak firewall defense	7-8	Install and regularly update the antivirus program. Have a secure firewall in place.
2	Unauthorized access to sensitive data	Weak and common system/server passwords and unorganized access controls	8-10	Have strong password policies in place with two-factor authentication and implement access controls
3	Social Engineering (Phishing Attacks)	Lack of security awareness training among the company’s staff	8-10	Conduct security awareness training sessions with employees to identify and prevent social engineering attacks
4	Physical theft or unauthorized access to server rooms	Lack of physical security measures	5-7	Install surveillance cameras, access control systems, and alarm systems to improve your physical security

ISO 27001 risk assessment template

The overall objective of the risk assessment exercise is to implement a risk treatment plan using ISO 27001 controls list such that your organization’s residual risk is acceptable. The primary objective is business continuity. 

You will do well to keep this in mind while selecting a risk assessment and treatment template. While there are many free ISO 27001 risk assessment tools and templates,  choose one that fits your organization’s risk universe. A simple spreadsheet with a logical approach to asset-based risk management can also help here.

ISO 27001 risk assessment report

The ISO 27001 risk assessment report will provide an overview of what you find. It would be reviewed meticulously during your ISO 27001 internal audits as well as certification audits. It should include the following:

• List of information assets and asset owners, risk assessment framework (includes the criteria for accepting risk), and management approval for acceptance of residual risks, to name a few. 

• The risk treatment applied and the impact of the risk affecting the availability, integrity and confidentiality of each your assets after and before treatment.

• Order of priority for treating the risks, the controls applied, and target timeline for applying the treatment.

• A comprehensive risk management framework that describes all steps and relevant methods required to be carried out in terms of the risk assessment process. These include asset identification, threat & vulnerability identification, control analysis, business impact analysis, risk determination, control recommendations as well as results documentation.

These apart, your documentation should also include the evaluation periodicity of the controls. An internal audit of your controls will help find glaring gaps, if any, in the process. A gap analysis will help you ensure you are on the right track.
