Microsoft Internet Security and Acceleration (ISA) Server can be deployed as a dedicated firewall that acts as the secure gateway to the Internet for internal clients. ISA Server protects all communication between internal computers and the Internet. In a simple firewall scenario, the ISA Server computer has two network interface cards, one connected to the local network and one connected to the Internet. By setting the security access policies, you prevent unauthorized access and malicious content from entering the network. You can also restrict what traffic is allowed for each user and group, application, destination, content type, and schedule.
To assure users of safe and secure access to the Internet, and to shield the network from malicious attacks, the availability and internal health of the ISA Proxy server should be constantly monitored. The eG Enterprise Suite helps you in this regard!
