The primary reason to perform regular reviews of the cybersecurity threat landscape is to compare emerging trends with the existing organizational security posture, as this helps the information security manager to identify and prioritize the gaps and risks that need to be addressed. The cybersecurity threat landscape is dynamic and constantly evolving, and the organization's security posture may not be adequate or aligned with the current and future threats. By reviewing the threat landscape regularly, the information security manager can assess the effectiveness and maturity of the security program, and recommend appropriate actions and controls to improve the security posture and reduce the likelihood and impact of cyberattacks.
