What is the recommended best practice for virtualizing servers within a bank's data centers?

1. Combine all servers into a single virtual environment

2. Create separate virtual environments for web servers and domain controllers

3. Migrate all servers into a cloud infrastructure

4. Utilize only physical servers for security reasons

The correct answer is: Create separate virtual environments for web servers and domain controllers

The recommended best practice of creating separate virtual environments for web servers and domain controllers is crucial in a banking data center due to the need for security, compliance, and operational efficiency. Web servers are often exposed to the internet, making them more vulnerable to external threats. In contrast, domain controllers manage authentication and directory services, handling sensitive user credentials and security policies. By isolating these two types of servers into separate virtual environments, an organization can enforce stricter security controls and reduce potential attack surfaces. This separation enhances security by minimizing the risk that a breach in a web server could compromise the domain controller and, by extension, sensitive data. It allows for tailored security policies for different server roles and aids compliance with regulations that govern data protection in financial institutions. Additionally, having separate environments can facilitate easier management, disaster recovery, and performance optimization, ensuring smoother operations overall. Creating a single virtual environment for all servers could lead to security vulnerabilities wherein an attack on one server type could have cascading effects on others. Migrating all servers into a cloud infrastructure, while modern, may introduce compliance challenges related to data sovereignty and regulatory requirements specific to banks. Utilizing only physical servers might limit scalability and increase costs unnecessarily, while also not addressing the principle of separation of concerns critical in security
