DNS server

The ProLiant DL320 Security Server depends on a DNS server to resolve Internet host names. To provide DNS server support for the server, use:

Your ISP DNS server

Your own DNS server on the internal network

A caching-only DNS server on the ProLiant DL320 Security Server

A caching-only DNS server on a perimeter network segment

The simplest approach is to use your ISP DNS server. During the ProLiant DL320 Security Server setup process, set the DNS server address used by the ProLiant DL320 Security Server to use the IP address of the ISP DNS server to resolve Internet host names. If using a dial-up connection to connect to the Internet, your ISP automatically assigns both an IP address and a DNS server address to your dial-up interface. The drawback of using only the ISP DNS server is that DNS cannot be used to resolve computer names on the internal network.

If a DNS server already exists on the internal network, use it to resolve Internet host names. All Active Directory domains require at least one DNS server and use that DNS server to resolve Internet host names for your internal network clients. Configure the internal interface of the ProLiant DL320 Security Server to use this DNS server after configuring the internal network DNS server to resolve Internet names.

A caching-only DNS server does not contain DNS zone or domain information. Instead, it queries other DNS servers on the Internet for the IP address of a given host, and then caches the result before forwarding the answer to the computer requesting the name resolution. A caching-only DNS server can be installed on the ProLiant DL320 Security Server, and then the server can be configured to use itself as its DNS server.

Another caching-only DNS server solution takes advantage of a perimeter network configuration. If the ProLiant DL320 Security Server has three or more network interfaces, one of the network interfaces can be connected to a perimeter network. A caching-only DNS server can be installed and configured on the perimeter network. If a DNS server exists on the internal network, it can be configured to use the perimeter network DNS server as a forwarder.

For more information on DNS setup and configuration, see the Microsoft® Windows Server™ 2003 Help and Support Center or the Microsoft® Windows® 2000 Help.

DHCP server

A DHCP server assigns IP addresses to computers configured as DHCP clients. In a typical ProLiant DL320 Security Server configuration, the DHCP server assigns addresses to computers on the internal network and the VPN Clients network. The DHCP server itself can be located on:

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.
