The most common used in the risk assessment process
Adverse event or incident (threat, risk element)
An event that might affect safety in a negative way
Vulnerability
Weakness in a system, process, human or a building that could be exploited by a threat
Probability
A measure of how often an incident occurs
Consequence (of injuries)
Consequence is the impact of an event. It can affect the economy, reputation, loss of personal reputation, life and health or critical functions or lead to prosecution
Risk
Risk is a measure that combines the probability and consequences of an event.
Why should we carry out a risk assessment?
- Maintaining confidence in a system or service
- Compliance with legal obligations
- Maintain quality of service
- Maintaining an overview of information assets
- Protecting employees, students and citizens
- Help protect critical infrastructure
- Learning and dissemination of knowledge among the participants in a risk assessment workshop
Risk assessment methodology
When we undertake a risk assessment we:
- Identify adverse events, i.e. events that can lead to violations of information values regarding confidentiality, integrity and availability
- Assess the risk - probability combined with consequence - for each adverse event
- Evaluating and managing risks by proposing protection or controls that mitigate risks
