  • 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
  • Determine tactics, techniques, and procedures (TTPs) for intrusion sets
  • Examine network topologies to understand data flows through the network

  • Conduct research, analysis, and correlation across a wide variety of all source data sets (indications and warnings)
  • 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
  • Notify designated managers, cyber incident responders, and cybersecurity service provider team members of suspected cyber incidents and articulate the event's history, status, and potential impact for further action in accordance with the organization's cyber incident response plan
Approximately (25%) of the CNDA's time will be spent executing the following tasks:
  • Prepare and update manuals, instructions, and operating procedures
  • Evaluate established methods and procedures and prepare recommendations for changes in methods and practices where appropriate
