About this training

Most banking and fintech workloads run on Linux. This programme teaches administrators and engineers to build hardened server baselines, control privileged access, monitor for intrusion and respond when a host is compromised — with every control implemented hands-on in lab virtual machines.

Who it's for: System administrators, DevOps/SRE engineers and infrastructure security teams.
