The default gateway address and the DNS server address used by the computer on the LAN can be changed from the Control Panel. Create an access rule on the ProLiant DL320 Security Server. The access rule can be configured to allow a limited number of protocols outbound access to the Internet, allow a selected group of users access to a selected group of websites, or create a firewall rule allowing all the users on your LAN access to all sites at all times using virtually any protocol.

The following example demonstrates how to create a firewall rule that allows everyone access to all protocols to all sites at all times. To create the firewall rule:

1.In the scope pane of the ISA Server management console, expand the computer name, right-click the Firewall Policy node, and select New>Access Rule.

2.On the Welcome to the New Access Rule Wizard page, enter the name of the rule in the Access rule name text box. In this example, enter All IP Traffic Outbound from Internal, and click Next.

3.On the Rule Action page, select the Allow option, and click Next.

4.On the Protocols page, select the All outbound protocols option, and click Next.

5.On the Access Rule Sources page, click Add.

6.In the Add Network Entities dialog box, select the Networks folder.

7.Double-click the internal network, and click Close. The internal network appears in the This rule applies to traffic from these sources list.

8.Click Next.

9.On the Access Rule Destinations page, click Add.

10.In the Add Network Entities dialog box, select the Networks folder.

11.Double-click the external network, and click Close. The external network appears in the This rule applies to traffic sent to these destinations list.

12.Click Next.

13.On the User Sets page, confirm that All Users appears in the This rule applies to requests from the following user sets, and click Next.

14.On the Completing the New Access Rule Wizard page, click Finish.

15.Click Apply at the top of the scope pane to save the changes and update the firewall policy.

The Internet is now accessible from computers on the LAN. Consider strengthening security for outbound connections after confirming that the ProLiant DL320 Security Server successfully allows access to the Internet. An effective method for creating a secure access policy is to use the network templates included with ISA Server 2004. For detailed information about the network templates, see the ISA Server 2004 Help file.

HP Virus Throttle

HP Virus Throttle, a network packet-filtering feature that helps slow the spread of viruses, is automatically installed and enabled on your ProLiant DL320 Security Server. Virus Throttle monitors all outbound connection requests and counts the number of unique connections. It detects abnormal (virus-like) behavior in the requests and slows excessive connection requests to new hosts until you can determine if they are viral in nature and take action.

Configuring Virus Throttle

After Virus Throttle is installed, the Virus Throttle icon appears in the Microsoft® Windows® toolbar at the bottom of the screen. The parameters for the filter driver are set to the defaults. Any change made to the Virus Throttle filter driver parameters is made to all active instances of the Virus Throttle filter driver.

Microsoft Internet Security and Acceleration (ISA) Software specifications

HP Microsoft Internet Security and Acceleration (ISA) Software is a robust network security solution designed to safeguard business environments by offering a versatile platform for secure internet access. ISA Server integrates multiple functionalities that are essential for modern enterprise needs, helping organizations manage and protect their network infrastructure.

One of the main features of ISA Server is its firewall capabilities, which provide an essential barrier between internal networks and external threats. The software utilizes intelligent packet filtering to analyze incoming and outgoing traffic, ensuring that only legitimate communications are allowed while blocking potentially harmful activity. This helps to mitigate risks associated with external cyber threats and unauthorized access.

Another key feature is the built-in web caching technology. ISA Server improves network performance by caching frequently accessed websites and content. This reduces bandwidth usage and enhances response times for end-users, leading to increased productivity. By storing copies of web pages, ISA Server can serve them quickly to users, allowing enterprises to optimize their use of internet resources.

ISA Server also includes a powerful Virtual Private Network (VPN) feature, enabling secure remote access for employees. This technology supports secure connections over the internet, allowing users to access the corporate network and resources from anywhere in the world. The VPN capabilities ensure data encryption during transmission, protecting sensitive information from interception.

Moreover, ISA Server incorporates integrated threat management tools, which offer insights into potential security issues. These tools provide logging and reporting features that allow administrators to monitor traffic patterns and detect anomalies. This functionality is critical for identifying and responding to potential security breaches in real-time.

In addition to these features, ISA Server supports application-layer filtering, which enhances security further. This allows organizations to control access to specific applications and services while ensuring that malicious content cannot infiltrate the network.

Overall, HP Microsoft Internet Security and Acceleration Software is a comprehensive solution designed to address the complexities of network security in today’s digital landscape. Its combination of firewall protection, web caching, VPN capabilities, and application-layer filtering makes it an invaluable tool for organizations looking to secure their internet connectivity while optimizing performance and user experience. By leveraging advanced technologies and characteristics, ISA Server empowers businesses to operate safely and efficiently in an interconnected world.
