Strengthening Financial Institution Security with Cloud Services

Mirai Labs Team

Cloud Security

A traditional financial institution committed to safeguarding its assets and customer data, recognized the increasing sophistication of cyber threats and the growing stringency of regulatory requirements within the financial sector. Their existing security infrastructure, while robust for its time, was facing challenges in keeping pace with the evolving threat landscape and the need for greater scalability.

To address these challenges, Mirai Labs proposed and implemented a comprehensive security framework on a leading Cloud platform, leveraging a suite of advanced Cloud security services. For perimeter protection, Mirai Labs deployed services to mitigate Distributed Denial of Service (DDoS) attacks and implemented Web Application Firewall (WAF) to safeguard web applications against common web exploits and malicious bots.

Robust data protection was achieved through the implementation of services for encrypting sensitive data both at rest and in transit. Strong identity and access management practices were enforced through the implementation of granular policies and multi-factor authentication for all critical accounts.

Security Architect

To enhance threat detection and monitoring capabilities, a monitoring service was implemented to continuously monitor for malicious activity and unauthorized behavior, while a centralized platform provided for managing security alerts and monitoring compliance posture across the entire Cloud environment.

Furthermore, to enhance the efficiency and responsiveness of the security operations team, Mirai Labs implemented security automation, ensuring consistency and reducing manual errors.

Key Benefits

Enhanced protection against a wide range of cyber threats reduced the risk of successful attacks.
Adoption of Cloud security services facilitated improved compliance with key financial industry regulations
Increased visibility into security events and potential vulnerabilities enabled a more proactive and effective approach to security management.
Reduced the risk of costly data breaches and financial losses.
Automation of security tasks streamlined the operations of the security team, freeing up valuable resources to focus on more strategic security initiatives.
The resulting IT infrastructure was more resilient and better equipped to handle the ever-evolving landscape of cyber threats.
