System Security and Compliance Monitoring

Correct Answer: Security Information and Event Management (SIEM)

A SIEM tool can collect, analyze, and report on security-related events from different systems, which is helpful for conducting compliance audits. The other options, such as IDS, antivirus, and firewalls, mainly focus on preventing and detecting threats rather than auditing and monitoring system security.

Correct Answer: Intrusion Detection System (IDS)

IDS systems are specifically designed to detect signs of intrusion attempts and alert the system administrators. While other solutions like antivirus, firewalls, and DLP provide some degree of security, they are not designed specifically to detect intrusion attempts.

Correct Answer: Security Information and Event Management (SIEM)

Security Information and Event Management (SIEM) is the most appropriate solution for monitoring user access and preventing unauthorized access to file shares. SIEM systems collect and analyze log data from various sources across the network, including file servers, applications, and security devices. They provide real-time monitoring, alerting, and reporting capabilities, allowing security teams to detect and respond to suspicious activities quickly. SIEM can identify patterns of unauthorized access attempts, track user behavior, and correlate events from multiple sources to provide a comprehensive view of the security landscape. This enables the company to effectively monitor user access, detect anomalies, and prevent unauthorized access to file shares. While other options like IDS and firewalls are valuable security tools, SIEM offers a more holistic approach to monitoring and analyzing user access across the entire network infrastructure.
