What action should be taken to decrease risks in information security?

Applying appropriate controls is essential for decreasing risks in information security because it directly addresses vulnerabilities and potential threats to information assets. Controls can be administrative, technical, or physical in nature and are designed to mitigate identified risks, ensuring that security objectives are met.

When organizations implement the right controls, they can effectively reduce the likelihood of security incidents and enhance their overall security posture. This aligns closely with the principles of ISO 27001, which emphasizes the need for systematic risk management practices, including the selection of controls that are proportionate to the risks faced.

While providing additional funding, increasing staff training, and conducting regular audits can contribute to a stronger security environment, these actions are often supportive measures rather than direct risk mitigation strategies. Funding might help implement controls, training may enhance awareness and minimize human error, and audits are crucial for assessing effectiveness, but applying appropriate controls is the fundamental action that leads to a measurable reduction in security risks.
