The problem

CivicNexus Innovations was deployed with insecure configurations, leaving critical assets exposed to data breaches, ransomware and weak access controls.

What I built

  1. 01

    Conducted a group-level Asset-Threat-Vulnerability (ATV) analysis covering web servers, database servers and VDI instances.

  2. 02

    Implemented network-layer controls with firewall rules and Security Groups/NACLs enforcing least-privilege access.

  3. 03

    Hardened VM instances by managing access keys and hardening OS images; disabled non-essential services and applied patches.

  4. 04

    Implemented data-at-rest encryption and file-level permissions to protect sensitive urban and personnel data.

  5. 05

    Mapped all controls to ISO 27001 Annex A domains (A.5, A.8, A.12) for governance and compliance.
