Cyber Security Analyst

Real Time AnalystsJoin the team defending the Pacific's front line in cyberspace. Leidos is hiring Real Time Analysts to join the Network Assurance Team supporting DISA Pacific (DNC-PAC) at Ford Island, Joint Base Pearl Harbor-Hickam. This team serves as the Security Operations Center (SOC) for USPACOM and the broader DoD Information Network (DODIN/DISN), standing watch 24/7/365 to detect, analyze, and respond to threats against the boundary of the Department of Defense's global network. You'll work at the intersection of two missions: the established DISA SOC boundary defense operation that protects the DODIN's Pacific footprint, and the emerging Joint Fires Network (JFN) Security Operations Center supporting a next generation, TS/SCI-level sensor and detection environment being stood up at the same location. It's a rare opportunity to defend mature, mission-critical infrastructure while helping build a brand-new SOC capability from the ground up.What You'll Do: Boundary Cyber Defense & SOC OperationsMonitor, detect, and analyze intrusions, incidents, and threats across the DODIN/DISN boundary — Internet Access Points, Boundary Cloud Access Points, and related infrastructure — using DoD-approved network monitoring and traffic analysis tools on a 24/7/365 basis.Perform near real-time triage of security events, correlating alerts, netflow, IDS/IPS output, and raw packet captures to confirm or refute malicious activity.Conduct deep-dive analysis of "low and slow" activity to uncover unauthorized access that automated tools miss.Investigate and analyze events using SIEM platforms including Splunk, Elastic, and Microsoft Sentinel, and correlate sensor data through the ThunderDome cybersecurity suite.Apply the MITRE ATT&CK framework to characterize adversary tactics, techniques, and procedures, and to guide incident analysis and threat-hunting.Develop, tune, and recommend custom detection signatures and countermeasures to prevent or mitigate emerging threats.Document analysis and findings in the DoD-mandated incident reporting/ticketing system, and issue Situational Awareness Reports and TIPPERs to mission partners.Coordinate directly with the DISA Joint Operations Center (DJOC), USCYBERCOM, and peer SOCs to synchronize threat intelligence and incident response across the DODIN.Joint Fires Network (JFN) SOC SupportSupport stand-up and sustainment of a 24x7x365 Security Operations Center for the JFN IL-6 environment, focused on threat detection and continuous monitoring across JFN nodes.Conduct Syslog review and Elastic stack alerting to identify anomalies, and tune advanced sensors such as Corelight as the SOC matures.Triage, escalate, and track incidents through JIRA using standardized SOC intake and escalation processes.Handle TS/SCI-level incidents in accordance with DIA-aligned requirements, ensuring spills, breaches, or anomalies are reported through authorized channels within mandated timelines.Develop threat-hunting playbooks focused on behavioral anomalies and traffic pattern analysis as the mission matures from initial monitoring into full detection and response.Work from a Sensitive Compartmented Information Facility (SCIF) at DISA Pacific, Ford Island.What You'll Need for Success:Active Top Secret security clearance with eligibility/ability to obtain SCIEducation and experience requirements depending on job level, as follows:Level II: Bachelor's degree and 2+ years of relevant experience; equivalent work experience and/or military service may be considered in lieu of a degree.Level III: Bachelor's degree and 4+ years of relevant experience; equivalent work experience and/or military service may be considered in lieu of a degree.Qualifications/credentials compliant with DoD 8140 DCWF Code 531, Cyber Defense Analyst at the Intermediate proficiency level.Hands-on experience with Computer Network Defense duties — protect, defend, respond, and sustain.Strong networking fundamentals, including communication protocols and common security tooling (IDS/IPS, firewalls).Experience evaluating packet captures and analyzing raw network traffic.Willingness and ability to work rotating shifts in support of 24/7/365 operations, including some after-hours and surge support.Preferred QualificationsAI capability development and implementation to automate analysis and detection tasks.Working knowledge of adversary tactics, techniques, and procedures (TTPs), and familiarity with MITRE ATT&CK and the Cyber Kill Chain.Direct experience with Splunk, Elastic, or similar SIEM/detection platforms.Familiarity with JIRA-based incident workflows and/or SOC intake and escalation processes.Understanding of software exploits, and experience analyzing packed or obfuscated code.Why This Role?Direct, high-visibility mission impact defending USPACOM and DODIN/DISN infrastructure in a strategically critical theater.Ground-floor opportunity to help build a new SOC capability alongside an established, mature SOC operation.Daily collaboration with DISA, USCYBERCOM, and Government leadership — direct exposure to enterprise-level cyber defense decision-making.Long-term program stability: multi-year task order (base plus four option years) with an established incumbent team.
