The best implementation to give the best central visibility into the events occurring throughout the corporate environment without logging in to the servers individually is B. Configure the servers to forward logs to a SIEM.

A SIEM (Security Information and Event Management) is a security solution that helps organizations detect, analyze, and respond to security threats before they disrupt business1. SIEM tools collect, aggregate, and correlate log data from various sources across an organization’s network, such as applications, devices, servers, and users. SIEM tools also provide real-time alerts, dashboards, reports, and incident response capabilities to help security teams identify and mitigate cyberattacks2345.

By configuring the servers to forward logs to a SIEM, the security analysts can have a central view of potential threats and monitor security incidents across the corporate environment without logging in to the servers individually. This can save time, improve efficiency, and enhance security posture2345.

Deploying a database to aggregate the logging (A) may not provide the same level of analysis, correlation, and alerting as a SIEM tool. Sharing the log directory on each server to allow local access © may not be scalable or secure for a large number of servers. Automating the emailing of logs to the analysts (D) may not be timely or effective for real-time threat detection and response. Therefore, B is the best option among the choices given.

Key Performance Indicators (KPIs)track the effectiveness of a security program, providing measurable insights intovulnerability detection, patching efficiency, and risk reduction. This makes KPIs ideal for executive dashboards​.

Option B (MOU - Memorandum of Understanding)refers toagreements between parties, not performance tracking.

Option C (SLO - Service Level Objective)defines operationaltargetsbut is nota tracking metric.

Option D (SLA - Service Level Agreement)defines expectations betweenservice providers and clients, not security metrics.

Thus,A (KPI) is the correct answer, asKPIs provide actionable insights into security effectiveness​.

Time synchronization is the process of ensuring that all systems in a network have the same accurate time, which is essential for correlating data points from different sources. If the system has an issue with time synchronization, the analyst may have difficulty matching events that occurred at the same time or in a specific order. Access rights, network segmentation, and invalid playbook are not directly related to the issue of correlating data points.

Agent-based vulnerability scanning is a method that uses software agents installed on the target systems to scan for vulnerabilities. This method meets the requirements of the project because it uses minimal network bandwidth and host resources, provides accurate and near real-time updates, and does not require any stored credentials on the scanner.
