During April 2025, Cintia Gloker focused on security hardening for the LBHackney-IT/Data-Platform repository, addressing network access for Qlik Sense. She implemented targeted ingress restrictions, updating security group rules to limit HTTP and HTTPS exposure to a designated IP range rather than allowing open access to all IPv4 and IPv6 addresses. Using Terraform and leveraging her expertise in cloud security and infrastructure as code, Cintia validated these changes in a staging environment to ensure alignment with organizational network policies. This work improved the platform’s security posture and prepared the updated configuration for a safe and controlled production rollout.
