When I review a larger organisation's risk assessment I want to see the main information security risks set out clearly with the controls that manage them. This example does exactly that and gives you a strong basis for your own assessment and risk register.

Effective form templates

This example risk assessment has been prepared using the
F-Q36 General Risk Assessment form template - a purpose-built template designed to focus entirely on what matters: identifying business risks, assessing their likelihood and impact, and recording the controls that manage them, without any unnecessary fields getting in the way.

The file is supplied in fully editable MS Word format and can be easily customised and saved to Google Docs format if required. The document uses pre-defined style formatting throughout with styles to match the risk-ratings which are input using select boxes pre-populated with all possible risk ratings. All text is in Calibri font for improved readability.
The following document labelling is included in the footer:

  • Form number and title
  • Information-classification
  • Version
  • Page number / total pages

Information Security Risk Assessment (Larger Organisation)

This fully completed information security risk assessment example has been prepared by experienced ISO management system consultants. It covers information security across the IT systems and data of a larger organisation operating its own on-premise IT infrastructure, and can be used as a starting point when developing your own information security risk assessment.

What Does This Information Security Risk Assessment Cover?

This risk assessment identifies the key information security risks a larger organisation faces, including:

  • Phishing, social engineering, malware and ransomware
  • Identity and access management, including privileged access and multi-factor authentication
  • Network, firewall and server infrastructure security
  • Logging, monitoring and incident detection and response
  • Software, patch, change and configuration management
  • Backups, system resilience and business continuity
  • Third-party access, data classification and legal and regulatory compliance

A residual risk rating is then assigned to each risk, demonstrating how layered controls - such as endpoint protection, network segmentation, least-privilege access, logging and monitoring, structured patching and tested backups - reduce the overall risk to a tolerable level.

A Professional Easy-to-Use Risk Assessment Template

This document uses colour-coded header styles matched to risk ratings, making it quick to read and easy to communicate during team briefings and staff training. A built-in risk rating matrix supports consistent evaluation of likelihood and consequence, and clear risk symbols help communicate each risk at a glance. An inherent and a residual rating are recorded for every risk, so the effect of your controls is easy to demonstrate.

Risk, Control and Prohibition Symbols

Each row in the assessment is tagged with a small symbol so the type of risk, the control that manages it and any prohibition are clear at a glance. The same icon set runs across every alphaZ business risk assessment, which keeps a finished document quick to read and easy to compare. You can read more about them in our blog post on the alphaZ business risk icons.

Who Is This Information Security Risk Assessment Suitable For?

This template is suitable for larger organisations that run their own IT infrastructure and need to identify, assess and document information security risk in depth. It is particularly useful when implementing or maintaining an information security management system aligned with ISO 27001, and when supporting the risks and opportunities requirements (clause 6.1) of ISO management system standards. IT and security managers, compliance leads and management system managers can all use it as a ready-made starting point.
