Client Overview

Industry: Financial Services

Objective: Strengthen cloud infrastructure security and reduce vulnerability exposure across all environments

Challenge: Rapid growth, complex hybrid cloud environment, and increasing vulnerability risks from legacy systems, third-party integrations, and misconfigurations.

Informatrix IT Team Role

Function: Informatrix IT Solutions Private Limited, specializing in infrastructure security, compliance, and 24/7 monitoring.

Goal: Assist the client in identifying, prioritizing, and remediating vulnerabilities in AWS workloads by delivering automated assessment tools, secure configuration baselines, and continuous monitoring support.

Project Approach and Key Actions

1. Vulnerability Assessment and Scope Definition

  • Conducted a full-scale vulnerability scan using Amazon Inspector, targeting EC2 instances, containers, and application layers.

  • Defined the assessment scope to include publicly exposed services, critical workloads, and third-party integrations vulnerable to common exploits.

2. Risk Prioritization and Remediation Planning

  • Triaged vulnerabilities using CVSS scores and business impact analysis.

  • Built a phased remediation plan, focusing on high-severity vulnerabilities with immediate business risk.

  • Integrated findings into AWS Security Hub for centralized visibility and prioritization.

3. Automated Patch Management and Secure Configurations

  • Used AWS Systems Manager Patch Manager to automate OS-level patching across EC2 environments.

  • Deployed AWS Config Rules and AWS Identity and Access Management (IAM) Access Analyzer to enforce secure configurations and reduce misconfigurations.

  • Hardened system images and applied Amazon Inspector container image scans to secure CI/CD pipelines.

4. Access Controls and Monitoring

  • Enabled role-based access control (RBAC) using IAM policies, and enforced multi-factor authentication (MFA) for all privileged accounts.

  • Deployed AWS CloudTrail and Amazon GuardDuty for real-time logging and anomaly detection.

5. Post-Remediation Validation and Continuous Monitoring

  • Re-ran assessments to validate vulnerability closure and ensure compliance with internal security policies.

  • Established recurring vulnerability scans and alerting using CloudWatch and Lambda scripts for auto-remediation of known issues.

  • Provided training to internal teams on secure coding practices and real-time incident response.

Results and Outcomes

  • Vulnerability Reduction: Reduced high and critical vulnerabilities by 94% in six weeks, meeting internal compliance SLAs.

  • Improved Visibility: Centralized vulnerability management with AWS Security Hub and real-time threat alerts via GuardDuty.

  • Faster Remediation: Cut mean time to patch from 14 days to 48 hours using Systems Manager automation.

  • Audit-Ready Security Posture: Enabled quarterly compliance scans and continuous monitoring, preparing the client for third-party audits and internal reviews.
