Cyber Attack Business Risk Assessment

This fully completed cyber attack business risk assessment example has been prepared by experienced ISO management system consultants. It covers the main forms of attack an organisation faces and how it prevents, detects, responds to and recovers from them, including phishing, malware and ransomware, hacking, denial-of-service, web application attacks and data breach. It can be used as a starting point when developing your own business risk assessment documentation.

What Does This Cyber Attack Business Risk Assessment Cover?

This risk assessment identifies the key cyber attack risks an organisation faces, including:

  • Phishing and social engineering aimed at staff
  • Malware and ransomware infection
  • Hacking and unauthorised access to systems
  • Denial-of-service attacks affecting availability
  • Website and web application attacks
  • Credential theft and account takeover
  • Supply chain and third-party attacks
  • Data breach and exfiltration
  • Detection, response and recovery when prevention fails

A residual risk rating is then assigned to each risk, demonstrating how effective controls - such as staff awareness, multi-factor authentication, anti-malware and patching, network protection, monitoring and tested incident response - 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 Cyber Attack Business Risk Assessment Template Suitable For?

This template is suitable for organisations of any size that need to identify, assess and document the risk of cyber attack. 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. Directors, IT and security leads and management system managers can all use it as a practical, ready-made starting point.
