Name one type of risk mitigation strategy.

Implementation of security controls is a well-established and effective risk mitigation strategy. This approach focuses on reducing vulnerabilities that may expose an organization to potential threats. Security controls can include a range of measures, such as firewalls, intrusion detection systems, access control mechanisms, data encryption, and regular security audits. These controls help create layers of protection that can deter, detect, and respond to cybersecurity incidents, thus significantly lowering the risk profile of an organization.

In contrast, the other options may not directly address the risks. For instance, increasing the number of employees in the IT department does not inherently reduce risks unless those additional staff members are effectively trained and involved in implementing and managing security protocols. Outsourcing IT services may transfer some risks but does not fundamentally reduce the inherent cybersecurity risks that need to be managed effectively. Finally, reducing the size of the organization does not necessarily mitigate risks; it may even introduce new vulnerabilities if critical personnel or resources are lost. Therefore, the implementation of security controls stands out as a proactive and focused method for risk mitigation.
