Final answer:
Egress monitoring systems, such as Data Loss Prevention solutions and Web Application Firewalls, are designed to prevent data exfiltration by monitoring network traffic and blocking unauthorized data transmission.
Step-by-step explanation:
An egress monitoring system is designed to prevent data exfiltration, which refers to unauthorized data leaving a network. These systems monitor network traffic and detect and block any attempts to transmit sensitive data outside of the network.
One example of an egress monitoring system is a Data Loss Prevention (DLP) solution. DLP systems use policies and rules to identify and prevent the exfiltration of sensitive information, such as customer data or intellectual property.
Another example is a Web Application Firewall (WAF), which can prevent the transmission of sensitive data through web applications by monitoring and filtering network traffic.
