Information security is crucial for businesses of all sizes in today's digital world. Conducting an information security risk assessment can help identify potential threats to your organization's data and IT infrastructure. In this blog post, we'll provide a simplified guide to creating an information security risk assessment, making the process more accessible and straightforward.

Step 1: Identify Data Sources & Determine Potential Threats

Start by brainstorming all possible threats to your information systems, including cyber-attacks, data breaches, natural disasters, and human error. Make a list of both internal and external threats to help you understand the full range of potential issues.

The best tools at your disposal here are a Data Asset Register (which includes a list of data processing activities), SWOT, PESTLE & Stakeholder analysis. These documents should then feed into the first stage of your risk assessment.

Step 2: Analyse the Risks – What can go wrong (always think worst case) and as a starting point categorise into high/med/low. Prioritise high risks through to low risks.

For each identified threat, consider the potential consequences for your organization, including financial loss, reputational damage, and operational disruptions. Prioritize the risks based on their potential impact, focusing on the most severe consequences and the most likely events.

Step 3: Determine Control Measures

Identify appropriate control measures for each risk, aiming to eliminate or reduce the potential impact. Consider technical solutions like MFA (multi-factor authentication), firewalls, and encryption, as well as administrative controls such as policies, procedures, and employee training. We will talk about control measures in more detail in our next post, as there is a great hierarchy to work from. As always, the first point is to determine whether can the risk be eliminated.

Another point that is often overlooked is to engage and communicate with your team – they may just be the answer to the most effective controls.

Step 4: Implement and Maintain Controls

Put the identified control measures into practice, ensuring that your employees are well-trained and aware of the measures. Regularly review and update the controls to maintain their effectiveness and adapt to any changes in the threat landscape.

A little tip I learned from working as a legal expert – have evidence of communication in all cases. Documentation is worth nothing without having communicated it.

It’s not the documentation that is important but rather the evidence and records to support that it’s actually effective.

Step 5: Monitor and Review

Periodically review your information security risk assessment to ensure that it remains relevant and up-to-date. Update the assessment when significant changes occur, such as the introduction of new technology, changes in your organization's operations, or shifts in the external environment.

In Conclusion,

Creating an information security risk assessment doesn't have to be complicated. By following these simplified steps, you can gain a better understanding of your organisation's potential threats and implement appropriate measures to protect your valuable data and IT infrastructure. Regular monitoring and reviews will help ensure that your risk assessment remains effective and current, allowing you to adapt to the ever-changing digital landscape.
