• • Apply zero-trust security principles to restrict unauthorized access. 

2. Automating Compliance & Monitoring

• • Deploy Security Information and Event Management (SIEM) tools. 

• • Use automated compliance tracking solutions to meet audit requirements. 

3. Conducting Regular Risk Assessments & Testing

• • Perform penetration tests and vulnerability scans at least annually. 

• • Simulate ransomware and phishing attack scenarios to test response plans. 

4. Strengthening Identity & Access Management (IAM)

• • Enforce least privilege access policies for financial data. 

• • Require MFA for all employees, vendors, and privileged accounts. 

5. Creating a Robust Incident Response Plan (IRP)

• • Develop automated response playbooks for ransomware, DDoS, and insider threats.
