Case Studies

Multiple production servers experienced recurring crypto-mining infections that survived repeated cleanup attempts. Business continuity required production to remain online throughout the investigation.

• Performed forensic investigation to identify dormant persistence mechanisms.

• Traced scheduled cron jobs responsible for reinfection.

• Developed automated cleanup tooling.

• Validated system integrity after remediation.

• Zero production downtime.

• Estimated ₹50L+ in avoided business losses.

• Stable post-incident audits with no recurring compromise.

Operational health was measured primarily through user complaints and occasional CPU/RAM monitoring, leaving engineering teams with little visibility into system behaviour.

Designed a telemetry-first observability platform using:

• Elasticsearch / Logstash / Kibana.

• Filebeat / Metricbeat.

• Prometheus / Grafana.

• Faster root-cause analysis.

• Improved operational decision-making.

• Evidence-based incident investigations.

• Transition from reactive monitoring to predictive operations.

Production, staging, and development environments behaved inconsistently, leading to repeated deployment issues and unnecessary regression cycles.

Implemented:

• Role-Based Access Control

• Environment standardization

• Patch governance

• Separation of duties

• Centralized observability

• Secure deployment practices

• Regression frequency reduced by 50 - 70%.

• Improved deployment consistency.

• Reduced operational risk across environments.

• Aligned the environment with CIS Benchmarks, and organizational governance requirements.

Security operations required greater visibility, governance, and compliance across AWS infrastructure supporting regulated environments.

Designed and implemented an integrated security operations platform combining:

• Wazuh

• TheHive

• AWS QuickSight

• Security analytics

• Incident response workflows

• Compliance reporting

• Improved incident visibility.

• Consistent audit readiness.

• Zero critical production outages.

• Long-term operational resilience across multiple organizational transitions.
