A company to demonstrate and implement a strong information security framework in order to comply with regulatory requirements as well as to gain customers’ confidence. ISO 27001 is an international standard designed and formulated to help create a robust information security management system. It is a systematic approach to managing confidential or sensitive corporate information so that it remains secure (which means available, confidential and with its integrity intact). ISO27001 explicitly requires risk assessment to be carried out before any controls are selected and implemented.
For ISO 27001 is designed to help you in this task. Although specifics might differ from company to company, the overall goals of risk assessment that need to be met are essentially the same, and are as follows. Identify risk. Determine if existing control measures are adequate as per company’s appetite for risk.
Reduce the level of its risk by adding precautions or control measures, as necessary. What is risk assessment?
To start from the basics, risk is the probability of occurrence of an incident that causes harm (in terms of the information security definition) to an informational asset (or the loss of the asset). In essence, risk is a measure of the extent to which an entity is threatened by a potential circumstance or event. It’s typically a function of the adverse impacts that would arise if the circumstance or event occurs, and the likelihood of occurrence. The purpose of risk assessment is to identify:. Threats to organizations (i.e., operations, assets, or individuals) or threats directed through organizations against other organizations or the nation. Vulnerabilities internal and external to organizations. Adverse impact to organizations that may occur given the potential for threats exploiting vulnerabilities.
The likelihood that harm will occur. The end result is determination of risk—that is, the degree and likelihood of harm occurring. Provides a step-by-step approach to carrying out the risk assessment under ISO27001:. Calculate the asset value. Identify vulnerability. Identify threats. Wolff montego bay tanning bed manual. Identify probability of threat and impact severity.
Calculate risk score. Ascertain and establish controls. Identify the assets and their value Identifying assets is the first step of risk assessment. Anything that has value and is important to the business is an asset. Software, hardware, documentation, company secrets, physical assets and people assets are all different types of assets and should be documented under their respective categories using the risk assessment template. To establish the value of an asset, use the following parameters:.
Cost of the actual asset. Cost to reproduce it. Cost if stolen. Value of intellectual property. Price others are willing to pay for the asset.
Cost to protect the asset. Once this is done, map each asset to its confidentiality, integrity and availability (CIA) levels and arrive at a rating. Typically, the categories for asset value could be Very High, High, Low and Medium. Identify vulnerabilities Vulnerabilities of the assets captured in the risk assessment should be listed. The vulnerabilities should be assigned values against the CIA values. A vulnerability is the existence of a weakness, or error in design/implementation, that can lead to an unexpected, undesirable event compromising the security of the system, network, application, or process involved. The goal here is to identify vulnerabilities associated with each threat to produce a threat/vulnerability pair.
Vulnerabilities could be categorized as Very High, High, Low, and Medium. Identify threats A threat is a potential event that may cause an unwanted, harmful incident. In the risk assessment template, threats are generally categorized under headings such as malicious activity, malfunction, people and environmental and then scored as Very High, High, Medium, or Low.
Identify probability and business impact of potential threats. More ISO 27001 stories. The next step using is to quantify the probability and business impact of potential threats as follows:. Frequency with which the threat could take advantage of the vulnerability. Productivity loss and cost.
Extent and cost of physical damage that the threat could cause. Value lost if confidential information is leaked. Cost of recovering from a virus attack. The impact severity is calculated as shown below Impact severity = Asset value x threat severity x vulnerability severity Determine the probability that a threat will exploit vulnerability. Probability of occurrence is based on a number of factors that include system architecture, system environment, information system access and existing controls; the presence, motivation, tenacity, strength and nature of the threat; the presence of vulnerabilities; and, the effectiveness of existing controls. Calculate risk score The risk score is calculated as follows Risk Score = Impact severity x probability The risk score may be depicted as below: Risk Score Description Low Accept Medium May need to add additional control High Need to treat Very High Requires immediate attention Risk treatment plan After the risk assessment template is fleshed out, you need to identify countermeasures and solutions to minimize or eliminate potential damage from identified threats.
A security countermeasure must make good business sense, meaning that it must be cost-effective, with benefits outweighing the costs. This requires a cost/benefit analysis. A commonly used cost/benefit calculation for a given safeguard is: (ALE before implementing safeguard) – (ALE after implementing safeguard) – (annual cost of safeguard) = value of safeguard to the company.

. Risk assessment (often called risk analysis) is probably the most complex part of implementation; but at the same time risk assessment (and treatment) is the most important step at the beginning of your information security project – it sets the foundations for information security in your company. The question is – why is it so important? The answer is quite simple although not understood by many people: the main philosophy of ISO 27001 is to find out which incidents could occur (i.e. Assess the risks) and then find the most appropriate ways to avoid such incidents (i.e. Treat the risks). Not only this, you also have to assess the importance of each risk so that you can focus on the most important ones.
Although risk assessment and treatment (together: risk management) is a complex job, it is very often unnecessarily mystified. These 6 basic steps will shed light on what you have to do. Risk assessment methodology This is the first step on your voyage through risk management.
You need to define rules on how you are going to perform the risk management because you want your whole organization to do it the same way – the biggest problem with risk assessment happens if different parts of the organization perform it in a different way. Therefore, you need to define whether you want qualitative or quantitative risk assessment, which scales you will use for qualitative assessment, what will be the acceptable level of risk, etc. Pokemon ash gray 4.5.3. Risk assessment implementation Once you know the rules, you can start finding out which potential problems could happen to you – you need to list all your assets, then threats and vulnerabilities related to those assets, assess the impact and likelihood for each combination of assets/threats/vulnerabilities and finally calculate the level of risk. In my experience, companies are usually aware of only 30% of their risks. Therefore, you’ll probably find this kind of exercise quite revealing – when you are finished you’ll start to appreciate the effort you’ve made. Risk treatment implementation Of course, not all risks are created equal – you have to focus on the most important ones, so-called ‘unacceptable risks’.
There are four options you can choose from to mitigate each unacceptable risk:. Apply security controls from Annex A to decrease the risks – see this article. Transfer the risk to another party – e.g.
To an insurance company by buying an insurance policy. Avoid the risk by stopping an activity that is too risky, or by doing it in a completely different fashion. Accept the risk – if, for instance, the cost for mitigating that risk would be higher that the damage itself. This is where you need to get creative – how to decrease the risks with minimum investment. It would be the easiest if your budget was unlimited, but that is never going to happen. And I must tell you that unfortunately your management is right – it is possible to achieve the same result with less money – you only need to figure out how.
ISMS Risk Assessment Report Unlike previous steps, this one is quite boring – you need to document everything you’ve done so far. Not only for the auditors, but you may want to check yourself these results in a year or two. Statement of Applicability This document actually shows the security profile of your company – based on the results of the risk treatment you need to list all the controls you have implemented, why you have implemented them and how. This document is also very important because the certification auditor will use it as the main guideline for the audit. For details about this document, see article. Risk Treatment Plan This is the step where you have to move from theory to practice. Let’s be frank – all up to now this whole risk management job was purely theoretical, but now it’s time to show some concrete results.
This is the purpose of Risk Treatment Plan – to define exactly who is going to implement each control, in which timeframe, with which budget, etc. I would prefer to call this document ‘Implementation Plan’ or ‘Action Plan’, but let’s stick to the terminology used in ISO 27001.

Once you’ve written this document, it is crucial to get your management approval because it will take considerable time and effort (and money) to implement all the controls that you have planned here. And without their commitment you won’t get any of these. And this is it – you’ve started your journey from not knowing how to setup your information security all the way to having a very clear picture of what you need to implement. The point is – ISO 27001 forces you to make this journey in a systematic way. ISO 27005 – how can it help you?
Iso 9001 Risk Assessment Template
ISO/IEC 27005 is a standard dedicated solely to information security risk management – it is very helpful if you want to get a deeper insight into information security risk assessment and treatment – that is, if you want to work as a consultant or perhaps as an information security / risk manager on a permanent basis. However, if you’re just looking to do risk assessment once a year, that standard is probably not necessary for you. Download this free material to learn more:.
