Cyber Security Analyst II

To provide 2rd Tier response to security incidents in a 24/7/365 Cyber Security Operations Center. Ensure adherence to standard operating procedures for detecting, classifying, and reporting incidents. Provide detection and troubleshooting support for cyber incidents escalated from Tier 1 analysts. Partner with Tier 3 staff to resolve cyber incidents. Works under minimal supervision.

• 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 event's history, status, and potential impact for further action) that may cause ongoing and immediate impact to 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
• Perform security reviews and identify security gaps in security architecture resulting in recommendations for inclusion in the risk mitigation strategy
• Receive and analyze network alerts from various sources within the enterprise and determine possible causes of such 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
• Recommend computing environment vulnerability corrections
• 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
• Isolate and remove malware
• 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 which 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
• Analyze and report organizational security posture trends
• Analyze and report system security posture trends
• Assess adequate access controls based on principles of least privilege and need-to-know
• Monitor external data sources (e.g., cyber defense vendor sites, Computer Emergency Response Teams, Security Focus) to maintain currency of cyber defense threat condition and determine which security issues may have an impact on the enterprise
• Assess and monitor cybersecurity related to system implementation and testing practices
• Provides cybersecurity recommendations to leadership based on significant threats and vulnerabilities
• Work with stakeholders to resolve computer security incidents and vulnerability compliance
• Provide advice and input for Disaster Recovery, Contingency, and Continuity of Operations Plans
• Coordinate and provide expert technical support to enterprise-wide cyber defense technicians to resolve cyber defense incidents
• Correlate incident data to identify specific vulnerabilities and make recommendations that enable expeditious remediation
• Perform analysis of log files from a variety of sources (e.g., individual host logs, network traffic logs, firewall logs, and intrusion detection system [IDS] logs) to identify possible threats to network security
• Perform cyber defense incident triage, to include determining scope, urgency, and potential impact, identifying the specific vulnerability, and making recommendations that enable expeditious remediation
• Perform initial, forensically sound collection of images and inspect to discern possible mitigation/remediation on enterprise systems
• Perform real-time cyber defense incident handling (e.g., forensic collections, intrusion correlation and tracking, threat analysis, and direct system remediation) tasks to support Incident Response Teams (IRTs)
