What is Risk Acceptance in Cybersecurity?
Risk acceptance in cybersecurity refers to the conscious decision by an organization’s leadership to acknowledge and accept the potential consequences of a specific cybersecurity risk without taking further action to mitigate or transfer that risk.
Risk acceptance is one of four (4) options to address identified risks:
- Reduce the risk to an acceptable level;
- Avoid the risk;
- Transfer the risk to another party; or
- Accept the risk.
To manage an organization’s risk, an organization’s leadership needs to adhere to its stated risk tolerance. Accepting the risk is the least favorable option, but this can occur after a thorough risk assessment process where risks are identified, analyzed and evaluated. Risk acceptance typically happens when the cost of mitigating a risk outweighs the benefit, or when the risk is deemed low enough that it falls within the organization's risk tolerance or appetite. For example, an organization might accept the risk of using a legacy system because the expense and complexity of upgrading outweigh the potential impact of a security incident.
To accept risk, organizations should document the following criteria to defend the position, in case it is questioned in the future:
- The nature of the risk being accepted;
- The reasons for acceptance (cost, operational impact, etc.);
- The potential impact of the risk;
- The duration of the acceptance; and
- The responsible personnel approving the decision.
Risk acceptance is a critical component of risk management and helps ensure transparency and accountability. It also requires continuous monitoring to detect any changes in the risk environment that might necessitate re-evaluation.
