ARSIEM is looking for a Cyber Network Defense Analyst to monitor network activity and identify and report events that occur, or might occur, within the network, in order to protect information, information systems, and networks from threats. CNDAs review data collected to analyze cyber events and the network environment, identifying trends, patterns, or anomaly correlations that indicate more serious attacks or future threats. The CNDAs will recommend proactive measures to contain the incident. These proactive measures include, but are not limited to, identifying intruders, local changes/suspect interactions; isolation; in-depth digital media analysis; consultation with law enforcement or counterintelligence organizations; development of signatures to detect this malicious behavior; and development and deployment of eradication tools.  This position will support one of our Government clients in Arlington, VA.

Responsibilities

• The majority of the CNDA's time (75%) will be spent executing the following tasks:

• 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 the event's history, status, and potential impact for further action) that may cause ongoing and immediate impact on 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 attacks/intrusions, anomalous activities, and misuse activities, and distinguish these incidents and events from benign activities.
