PRIMARY RESPONSIBILITIES:

• Perform computer network incident detection, and response activities to detect, correlate, identify and characterize anomalous activity that may be indicative of threats to the enterprise.
• Monitor various security tools and applications for possible malicious activities, investigate any associated alerts or indicators, and develop recommendations for a course of action, including mitigation strategies as necessary.
• Conduct analysis of low-level (“low and slow”) events to identify unauthorized activity utilizing exploratory problem-solving or self-learning techniques.
• Conduct near real-time event triage and analysis, which can result in network traffic validations or a Mission Partner’s incident report.
• Utilize formal monitoring policies and procedures that include the appropriate use of DoD-approved network monitoring and traffic analysis tools to assist with identifying suspicious, anomalous, or overtly malicious network traffic on a 24/7/365 basis.
• Review and analyze available logs in a timely manner to detect intruders and notify Mission Partners of activity through a formal reporting process/pending an incident report.
• Apply, develop, tune, and distribute or optimize new and existing countermeasures or guidance to prevent or mitigate potential cyber event impacts when possible.
• Perform network traffic analysis utilizing raw packet data, net flow, IDS, IPS and custom sensor output, as it pertains to the cyber security of communications networks.
• Understand attack signatures, tactics, techniques, and procedures associated with advanced threats.
• Requires good technical writing skills as each event, including the associated analysis, are documented in a ticketing system for review and action.
• Requires excellent communication skills as we are collocated with our customer and regular face-to-face interaction is necessary throughout the day, as well as significant coordination and communication between team members.
