DUTIES As a successful candidate for the Cyber Defense Analyst III role, you will collect and integrate information from multiple sources to monitor network activity and detect anomalous behavior; identify, triage, and report events to protect data, information systems, and infrastructure; analyze security‑relevant data to surface trends, patterns, and anomaly correlations; recommend proactive security measures; isolate indicators of compromise through focused analysis; and notify designated managers, cyber incident responders, and cybersecurity service provider team members of suspected incidents, clearly articulating event history, current status, and potential impact for further action in accordance with the organization's cyber incident response plan.

Required Skills SKILLS * Use cyber defense tools to monitor, detect, analyze, categorize, and perform initial triage of anomalous activity

• Generate cybersecurity cases (including event history, status, and potential impact for further action) and route as appropriate
• Leverage knowledge of commonly used network protocols and detection methods to defend against related abuses
• Apply cybersecurity and privacy principles to organizational requirements (confidentiality, integrity, availability, authentication, non‑repudiation)
• Perform advanced manual analysis to hunt previously unidentified threats
• Conduct PCAP analysis
• Identify cyber‑attack phases based on knowledge of common attack vectors and network layers, models, and protocols
• Apply techniques for detecting host‑ and network‑based intrusions
• Maintain working knowledge of enterprise‑level network intrusion detection/prevention systems and firewall capabilities
• Understand the foundations of a hardened Windows network and which native services and protocols are subject to abuse (RDP, Kerberos, NTLM, WMI, SMB)
• Demonstrate familiarity with the fragmentation of network traffic and how to detect and evaluate fragmentation‑related attacks in raw packet captures
• Conduct network traffic, protocol, packet‑level, and NetFlow analysis for anomalous values that may be security‑relevant using appropriate tools (Wireshark, TShark, tcpdump)
• Understand Snort filters and how they are crafted and tuned to feed IDS alerting
• Understand system and application security threats and vulnerabilities, including buffer overflow, SQL injection, race conditions, covert channel, replay, return‑oriented attacks, malicious code, and malicious scripting
• Analyze malicious activity to determine weaknesses exploited, exploitation methods, and effects on the system and information
• 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
• Be familiar with indications of Command and Control (C2) channels and strategies attackers use to bypass enterprise defenses from a compromised host
• Demonstrate advanced knowledge of how adversaries penetrate networks and how those attacks map to detectable events across the ATT&CK framework
• Understand how VBS, JScript, and PowerShell can be maliciously used within a network and what level of monitoring and auditing is required to detect
• Possess deep knowledge of Active Directory abuse used by attackers for lateral movement and persistence
• Provide expertise in the identification of adversarial Tactics, Techniques, and Procedures (TTPs) and in the development and deployment of signatures
• Perform after‑action reviews of team products to ensure completion of analysis
• Lead and mentor team members as a technical expert
