Operational IT risks 
What does the term 'operational IT risks' mean? Operational IT risks are 
business risks arising from a malfunction –loss of service availability, 
confidentiality and integrity – of IT systems, IT infrastructures or underlying 
facilities.  
Figure 4: Operation of information technology in a company 
Both business‐critical and non‐critical IT services support the company's 
business operations. If these business processes, e.g. sales, HR, finance and 
accounting, are no longer supported with the reliable IT that they require, 
business will be negatively affected. 
Cloud risks 
Cloud risks that can damage business processes on account of the potential 
unreliability of an IT service originating from the Cloud. So it is important to 
understand its effect on the company. Every malfunction that occurs in the 
Cloud, during transport or during provisioning to the business process adds 
to the risk factor.
Figure 4 illustrates a service provisioned from the Cloud in its total transport 
chain back to the user. This shows that the Cloud provider, the internet 
provider responsible for transport to the company, and the company's own 
IT infrastructure are responsible for reliability. In order to best manage the 
risks of using Cloud services, they should be taken into account when 
planning the necessary measures.
