Segmentation is a network design technique that divides the network into smaller and isolated segments based on logical or physical boundaries. Segmentation can help improve network security by limiting the scope of an attack, reducing the attack surface, and enforcing access control policies. Segmentation can also enhance network performance, scalability, and manageability. To accomplish the goal of storing customer data on a separate part of the network, the administrator can use segmentation technologies such as subnetting, VLANs, firewalls, routers, or switches.

Comprehensive and Detailed In-Depth Explanation:
Updating wire transfer processes to include verification steps (such as requiring dual approval or verifying account changes via a secondary communication method) can prevent fraudulent transactions. Attackers often use business email compromise (BEC) or pretexting to trick employees into transferring funds to fraudulent accounts.
* Standardizing security incident reporting is useful for tracking security events but does not prevent fraud in real time.
* Executing regular phishing campaigns improves awareness but does not enforce a verification process for financial transactions.
* Implementing insider threat detection focuses on internal risks but does not specifically prevent external fraud.
A more secure wire transfer process with additional verification steps is the most effective measure against fraudulent transactions.
