Project Approach and Key Actions
1. Assessment and Scope Definition
-
Initial Audit Assessment: Conducted a thorough gap analysis in collaboration with the client’s IT and compliance teams, identifying systems and data flows subject to regulatory scrutiny.
-
Scope Definition: Focused on high-risk areas, including sensitive data repositories, network access points, and legacy system integrations.
2. Network Security Enhancements
-
Network Segmentation: Enhanced segmentation to protect critical assets and reduce risks associated with lateral movement in case of unauthorized access.
-
Firewall and Intrusion Prevention: Updated firewall rules and intrusion detection/prevention systems to restrict unauthorized access attempts and bolster perimeter security.
3. Access Control and Data Protection
-
Role-Based Access Controls (RBAC): Implemented RBAC with the least privilege principle, ensuring users only had access necessary for their roles.
-
Multi-Factor Authentication (MFA): Enforced MFA across all user accounts to prevent unauthorized access, especially for privileged roles.
-
Data Encryption and Tokenization: Standardized encryption protocols and implemented tokenization to secure sensitive data in both legacy and modern systems.
4. Continuous Monitoring and Incident Response
-
SIEM Configuration and Alert Tuning: Optimized the Security Information and Event Management (SIEM) system to reduce false positives, enhancing efficiency in threat detection.
-
Incident Response Framework: Established a structured incident response plan for rapid escalation and mitigation of potential security incidents.
5. Compliance Audit Preparation
