About the RoleIn this role you are Tenneco’s security operations presence in AMER. You own detection triage and incident handling during the region’s business day, you are the analyst closest to the plants and offices in your footprint, and you can tell the difference between a genuine intrusion and a maintenance window nobody announced. You handle escalations from the managed detection partner, you drive incidents to containment locally, and you carry the regional regulatory and operational context that no general tool captures.
Responsibilities
- Own security alert triage, investigation, and escalation for the AMER region during regional coverage hours, and provide clean handover into the next region.
- Investigate escalations from the managed detection and response provider, validate findings independently against source telemetry, and reject weak analysis rather than passing it along.
- Lead containment and remediation for regional security incidents with regiona
