About the position

ARSIEM Corporation is seeking a Network Forensics Cybersecurity Analyst to support one of our Government clients in Arlington, VA. This role is critical in assisting the Government lead in coordinating teams during 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 requires a thorough assessment of network topology and device configurations to identify critical security concerns and provide recommendations for security best practices. The Network Forensics Cybersecurity Analyst will also be responsible for writing and publishing Computer Network Defense (CND) guidance and reports on incident findings to the appropriate constituencies. This includes collecting network intrusion artifacts such as PCAP, domains, URIs, and certificates, and using the discovered data to enable mitigation of potential CND incidents. The analyst will analyze identified malicious network activity to determine weaknesses exploited, exploitation methods, and the effects on systems and information. Additionally, the role involves collecting network device integrity data and analyzing it for signs of tampering or compromise. Real-time CND incident handling tasks will also be part of the responsibilities, including forensic collections, intrusion correlation, tracking, threat analysis, and advising on system remediation to support onsite engagements. This position offers a unique opportunity to work collaboratively across physical locations and contribute to the security posture of our government clients.
