Cyber Analyst

Description Join 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.

• Monitor, 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 Thunder Dome 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.

• Support 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 toidentifyanomalies, andtune advanced sensors such as Corelightas the SOC matures.

• Triage, elevate, and track incidents through JIRA using standardized SOC intake and escalation processes.

• Handle TS/SCI-level incidentsin accordance withDIA-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 frominitialmonitoring into full detection and response.

• Work from a Sensitive Compartmented Information Facility (SCIF) at DISA Pacific, Ford Island.

• Active Top Secret security clearance with eligibility/ability to obtain SCI

• Education 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 Intermediateproficiencylevel.

• 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.

• AI 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,…
