This includes analytical analysis of device communication, forensic analysis of Windows or Linux systems and servers, timeline analysis of activity on these endpoints, user permission and authentication audits, log analysis, and malware identification/triage. Experience with system administration, Windows and Linux operating systems (OS) mechanics and filesystem structures, disk and memory forensics, commonly abused tools/vectors for persistence, privilege escalation, and lateral movement, operating system log analysis, and triaging suspicious file artifacts for unusual behavior, with respect to the environment they are found in.Familiarity with what routine OS activities and common software/user behavior looks like in the context of forensic artifacts or timelines, as well as, common categories and formats of host-based indicators of compromise (IOCs) and how/where they can be leveraged to identify known-bad files/activity on an endpoint. Candidate will utilize the Cyber Kill Chain and define the entire attack life cycle along with creating detailed reports on how impacts may or have occurred. Reviews and provide feedback to journeyman and junior analysts' investigation and facilitate discussions on recommendations on improving SOC visibility, efficiency, and/or processes focus on identifying unusual files, scripts, configurations, and user activity based on bulk aggregation via an Endpoint Detection and Response (EDR) or triage tools, and coordinate forensics centric efforts with case management oversight.
