Sentar is seeking a Detection Engineer SME in Quantico, VA!

Role Description:

Sentar is seeking a Detection Engineering SME to support an active government contract providing Cyber Security Service Provider (CSSP) functions. This position will support the government's mission to disrupt, deny and degrade network adversaries’ ability to disrupt the IT services provided to network users.

The Contractor shall provide 8x5 support to produce detection use cases, which are discrete packages of signatures, correlation rules, and execution instructions for Incident Detection Monitoring personnel. These detection use cases address specific areas of concern and are based on the MITRE ATT&CK framework. Detection use cases provide the Government with a mechanism to prioritize detection resources and to measure detection resource capacity and performance.

The Contractor shall use all available logs and alerts from host operating systems, network intrusion prevention systems, endpoint detection and response tools, anti-virus and host intrusion prevention systems, and other sources to create the ability of the Government to detect malicious or unauthorized activity on its network.

The Contractor will Leverage Snort, Regex, and YARA (or similar methods) to apply logic needed to detect and alert malicious activity at various levels within the environment. The tools used may include Tanium, Microsoft Defender for Endpoint, Elastic/Kibana, and the tools included in the DoD’s Joint Regional Security Stack (JRSS). When alerts are determined to be false positives, the Contractor shall take action to modify the related detection use case, rule, or signature to eliminate future false positive results. These efforts will support the analysis and correlation of 800,000,000 events per day (on average), resulting in approximately 2,000 incidents in calendar year 2021. Personnel shall work eight hour shifts between the hours of 0700 and 1700 in the Eastern Time zone. The DoD Cyberspace Work Role for this task is 511- Cyber Defense Analyst.

Qualifications:

• Bachelor’s Degree in Computer Science or IT related field or at least five years of demonstrated experience in supporting DCO and/or network systems and technology.

• Experience leading operations and maintenance support for an enterprise-level (minimum of 50k users) network
• DODD 8570 IAT III certification: (CASP+, CCNP Security, CISA, CISSP, GCED, GCIH, or CCSP)
• DODD 8570 CSSP Analyst certification: (CEH, CFR, CCNA Cyber Ops, CCNA-Security, CySA+, GCIA, GCIH, GICSP, Cloud+, SCYBER, PenTest+)

The Detection Engineer position requires at least a few years of experience in a SOC working with SIEM/SOAR and analyzing incidents created by both custom and vendor signatures.
