What tool did Zack use to enhance the potential analytical capability for detecting insider threats?

The selection of AlienVault OSSIM as the tool used by Zack to enhance the analytical capability for detecting insider threats is significant due to its comprehensive approach to security information and event management (SIEM). AlienVault OSSIM integrates various security tools and data sources, allowing for the aggregation and analysis of security events. This capability is crucial for detecting insider threats, which often require correlating data from multiple systems to identify unusual patterns of behavior that might indicate malicious activities originating from within the organization.

Furthermore, OSSIM provides analysis features such as asset discovery, vulnerability assessment, and intrusion detection, which are essential for identifying both internal and external threats. By leveraging such a sophisticated tool, organizations are better equipped to analyze user behavior, understand potential risks, and respond to incidents proactively, making it particularly effective for detecting insider threats.

In contrast, while Splunk is also a powerful tool for analyzing data and logging, it typically focuses more on operational intelligence rather than specifically targeting insider threats. Wireshark, although useful for network protocol analysis, is more suited for network troubleshooting and packet inspection rather than comprehensive threat detection. Nessus is primarily a vulnerability scanner and, while important for identifying potential weaknesses, does not possess the same level of analytical capabilities for real-time incident monitoring and response
