Cyber Network Defense Analysts (CNDA)

Location: Arlington, VA

-Must have a Top Secret security clearance

Node is seeking Cyber Network Defense Analysts (CNDA) to support a critical customer mission. This opportunity provides onsite advanced Cyber Defense, rapid incident response, and immediate investigation and resolution using host-based, network-based and cloud-based cybersecurity analysis capabilities.

Team personnel provide a front-line response for digital forensics/incident response (DFIR) and proactively hunt for malicious cyber activity.

The CNDA 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 the information, information systems, and networks from threats.


- 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 that can be implemented on cyber defense network tools in response to new or observed threats within the network environment or enclave
