• Coordinate with enterprise-wide cyber defense staff to validate network alerts
• Document and escalate incidents (including event's history, status, and potential impact for further action) that may cause ongoing and immediate impact to the environment
• Perform cyber defense trend analysis and reporting
• Perform event correlation using information gathered from a variety of sources within the enterprise to gain situational awareness and determine the effectiveness of an observed attack
• 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

• Experience implementing incident handling methodologies
• Experience implementing protocol analyzers
• Experience collecting data from a variety of cyber defense resources
• Experience reading and interpreting signatures (e.g. snort)
• Experience performing packet-level analysis
• Experience conducting trend analysis

Desired Skills:  

• Python programming experience
• Strong math and science background
• Experience with Carnegie Mellon SiLK tool suite
