Cyber Network Defense Analysts (CNDA)

The Computer Network Defense Analyst 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. CNDAs review data collected to analyze cyber events, and the network environment, to find 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 measurers include, but are not limited to, identification of intruder 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.
