#RISK ASSESSMENT ISO 27001.XLS MANUAL#

Build a database of critical and valuable assets (for example, records of personal data) and assess events that might affect the security of each asset. Experienced practitioners know that too much granularity – therefore too many options – makes risk assessment more complex and less consistent.Īlso, consider an asset-based approach to risk assessment. The risk scale is the number of options your methodology allows for both in terms of impact and likelihood. Impact is more complex, and can involve financial loss, reputational damage, operational disruption and other factors, or a combination of these, all of which have to be reduced to a standard measure. A risk has to be likely to occur and, if it does, it has to have an impact on the organisation – otherwise, why worry about it? Likelihood is typically measured as frequency of occurrence (a typical scale might range from ‘once per year’ to ‘every second of every day’). Then, establish a ‘risk scale’ – that is, a combination of likelihood and impact. A risk assessment tool will help you identify which controls have been adopted. The point is you are starting with the context of your business, and the controls you are required to adopt in order to avoid fines and other sanctions, demonstrating to your customers and other stakeholders that you take the integrity of their data seriously. To set out such a process, begin by identifying the business, regulatory and contractual requirements you have to meet in respect of information security – this might include the requirements of the GDPR or PCI DSS, for example. In turn, this means your process must be objective, transparent and auditable, with a formal methodology that will produce consistent results each time, even when followed by different risk assessors. Establish a risk assessment frameworkĬlause 6.1.2 of ISO 27001 mandates that risk assessments must be ‘consistent, valid and comparable’. How then can an organisation ensure it follows and applies the best practice set out in this standard? Here are five steps organisations need to follow to ensure successful execution: 1. According to a survey carried out in 2017 involving more than 1,500 UK businesses, only 38 per cent of medium firms were aware of ISO 27001, while less than a quarter of small companies knew about it. There is also a general lack of awareness among SMEs.

The requirement to re-evaluate risk assessments on an annual basis makes these manual processes even more labour intensive, which is why businesses are increasingly adopting electronic, automated processes to remove the potential for human error and the burden of work. This is due in part to businesses continuing to rely on inefficient, time consuming and archaic methods of data collection, with spreadsheets piling high on security analysts’ desks. Nevertheless, ISO 27001 can be challenging to secure and maintain. It follows a risk-based approach to securing corporate information assets associated with people, processes and technology, ultimately delivering a logical framework and a clear audit trail, which is particularly helpful should an incident occur and your organisation be required to report to the ICO. While ISO 27001 is not mandatory, it is considered the gold standard, and is one that most organisations uphold as a means of demonstrating a best-practice information security management system (ISMS).
