Certified Incident Handler (CIH) Practice Ecam

The most appropriate tool for securing an organization from various network-based incidents among the given choices is Software Vulnerability Manager. This tool is specifically designed to identify, manage, and remediate vulnerabilities within software systems, which is crucial for incident response. In the context of network security, managing vulnerabilities helps prevent potential exploitation by attackers, thus enhancing the overall security posture of the organization. When vulnerabilities are effectively managed and mitigated, the chances of successful network-based incidents, including malware infections and unauthorized access, are significantly reduced. This proactive approach is critical for an incident response team, as it helps in preparing for, detecting, and mitigating incidents before they can escalate into damaging security breaches. While other tools listed may have their specific purposes, such as monitoring or managing specific aspects of a network or system (like Nagios XI for monitoring systems), they do not fundamentally offer the same level of vulnerability management that supports incident responders in securing an organization from various types of network-based incidents.
