Network Based Analyst II with Security Clearance

Provides remote and onsite advanced technical assistance, proactive hunting, rapid onsite incident response, and immediate investigation and resolution using host-based, network-based and cloud-based cybersecurity analysis capabilities. Team personnel provide front line response for digital forensics/incident response (DFIR) and proactively hunting for malicious cyber activity.
• We are seeking Cyber Network Defense Analysts (CNDA) to support this critical customer mission.
• The CDNA uses information collected from a variety of sources to monitor network activity and analyze it for evidence of suspicious behavior.
• Monitoring and analysis are performed to identify and report events that occur, or might occur, within the network, in order to protect information, information systems, and networks from threats. Responsibilities:
• Characterize and analyze network traffic to identify anomalous activity and potential threats to network resources
• 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 - Use cyber defense tools for continual monitoring and analysis of system activity to identify malicious activity

• 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 off network traffic - Identify network mapping and operating system (OS) fingerprinting activities
• Assist in the construction of signatures which can be implemented on cyber defense network tools in response to new or observed threats within the network environment or enclave Required Skills/Clearances:

• U.S. Citizenship - Active TS/SCI clearance - Ability to obtain Department of Homeland Security (DHS) Entry on Duty (EOD) Suitability - 2+ years of direct relevant experience in cyber defense analysis using leading edge technologies and industry standard cyber defense tools - Experience successfully developing and deploying signatures

• Experience detecting host and network-based intrusions via intrusion detection technologies (e.g., Snort) - 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 Required Education: BS Computer Science, Cyber Security, Computer Engineering, or related degree; or HS Diploma & 4+ years of network investigations experience. Desired Certifications: One or more of the following professional certifications: GNFA, GCIH, GCIA, GSEC, CASP+, CySA+, PaLMS, FedVTE
• GSEC (SANS401), Arcsight (or other SEIM solution), Network+, Security+
