GCyber is looking for a Cybersecurity Engineer to support a large Army customer. You should have a deep expertise in cybersecurity and technical proficiency to lead the analysis and correlation of compliance and vulnerability data across all managed endpoints. This role involves identifying critical assets, mapping traffic patterns, integrating various cybersecurity tools (e.g., firewall logs, ACAS/Tenable, HBSS/Trellix, Microsoft MDE/EDR), and generating actionable insights through Power BI dashboards. The Cybersecurity Engineer will need to assess the infrastructure for vulnerabilities and collaborate with stakeholders to produce advanced cyber analytics, visualizations, and risk-based reports.

As the Cybersecurity Engineer, you will:

• Critical Asset Identification & Network Analysis:

• Risk and Vulnerability Assessment:
  • Perform risk assessments by analyzing compliance, vulnerability, and traffic data to prioritize high-risk assets and vulnerabilities.
  • Use data from ACAS for vulnerability scanning and compare it with the MITRE ATT&CK framework to understand how adversaries could exploit the vulnerabilities.
  • Assess logs from EDR/MDE solutions to identify anomalous activities or indicators of compromise (IoCs).
• Security Tool Expertise:
  • Maintain a comprehensive understanding of security tools and their data outputs, including firewall logs (Cisco ASA, Palo Alto), endpoint protection platforms (HBSS/Trellix), and vulnerability scanning tools (Tenable/ACAS).
  • Identify how each tool's dataset correlates with others to provide comprehensive visibility of the network's security posture.
• Collaboration and Reporting:
  • Collaborate with Government stakeholders to design security dashboards that reflect organizational needs, including compliance metrics, vulnerability trends, and Plan of Action and Milestones (POA&M) status.
  • Lead efforts to produce reports and visualizations in Power BI that support proactive risk management and decision-making.
  • Provide briefings and reports along with recommendations to enhance the organization's security posture to Senior Leadership.
