- Provide daily summary reports of network events and activity relevant to cyber defense practices

- Receive and analyze network alerts from various sources within the enterprise and determine possible causes of alerts

- Provide timely detection, identification, and alerting of possible attacks/intrusions, anomalous activities, and misuse activities and distinguish these incidents and events from benign activities

- Analyze identified malicious activity to determine weaknesses exploited, exploitation methods, effects on system and information

- Identify and analyze anomalies in network traffic using metadata

- Validate intrusion detection system (IDS) alerts against network traffic using packet analysis tools

- Identify applications and operating systems of a network device based on network traffic

- Reconstruct a malicious attack or activity based on off-network traffic
