• Assess network topology and device configurations identifying critical security concerns and providing security best practice recommendations
• Collect network intrusion artifacts (e.g., PCAP, domains, URI's, certificates, etc.) and use discovered data to enable mitigation of potential Computer Network Defense incidents
• Analyze identified malicious network activity to determine weaknesses exploited, exploitation methods, effects on system and information
• Collect network device integrity data and analyze for signs of tampering or compromise
• Assist with real-time CND incident handling (i.e., forensic collections, intrusion correlation and tracking, threat analysis, and advising on system remediation) tasks to support onsite engagements
