Information Security Administrator

ITA Group Inc•Des Moines, IA

About The Position

The Information Security Administrator supports the protection of ITA Group's systems, networks, endpoints, cloud environments, applications, and data. This role performs security operations, investigates alerts, administers security technologies, supports incident response, and partners with internal technology teams and the organization's external Managed Detection and Response (MDR) provider. The Administrator is expected to be technically curious and capable of independently performing security triage and investigation when needed. The MDR is an operational partner, but internal accountability remains with ITA Group. This position validates provider findings, challenges incomplete conclusions, helps tune detections and playbooks, and contributes to the continued maturity of security operations.
