About the position

Node is seeking Network Forensics Cybersecurity Analysts to support a critical customer mission in Arlington, VA. This role requires a Top Secret Security Clearance and involves assisting the Government lead in coordinating teams for preliminary incident response investigations. The analyst will interface with the customer on-site, determining appropriate courses of action in response to identified and analyzed anomalous network activity. The position also entails assessing network topology and device configurations to identify critical security concerns and providing security best practice recommendations. In addition, the analyst will assist in writing and publishing Computer Network Defense guidance and reports on incident findings to appropriate constituencies. Collecting network intrusion artifacts such as PCAP, domains, URIs, and certificates is a key responsibility, as is using discovered data to enable mitigation of potential Computer Network Defense incidents. The role requires analyzing identified malicious network activity to determine weaknesses exploited, exploitation methods, and effects on systems and information. Real-time Computer Network Defense incident handling tasks, including forensic collections, intrusion correlation, tracking, threat analysis, and advising on system remediation, will also be part of the job. The analyst will provide technical briefings as required, ensuring effective communication of findings and recommendations to stakeholders.
