A security administrator monitoring network traffic for suspicious activity should implement which solution?

Implementing an Intrusion Detection System (IDS) is a key solution for a security administrator monitoring network traffic for suspicious activity. An IDS is specifically designed to detect and alert on potential threats or intrusions by analyzing network traffic and identifying patterns that may indicate malicious activity. This capability is critical for proactive security measures, as it allows organizations to identify breaches or attempted breaches in real-time, enabling faster responses to potential threats.

The effectiveness of an IDS lies in its ability to monitor and analyze traffic patterns, flagging any anomalies that deviate from expected normal behavior. This includes identifying unauthorized access attempts, unusual data flows, or other indicators of compromise that may signal a cyber threat. The alerts generated by an IDS provide security teams the necessary insights to investigate further and take action, enhancing the overall security posture of the organization.

While other solutions like File Integrity Monitoring (FIM), Security Information and Event Management (SIEM), and Data Loss Prevention (DLP) play important roles in a comprehensive security strategy, they serve different purposes. FIM focuses on ensuring the integrity of files by detecting unauthorized changes, SIEM aggregates and analyzes security data from across the network for broader threat detection and compliance monitoring, and DLP is primarily concerned with preventing the unauthorized transfer of sensitive
