1.Double-click the Virus Throttle icon to open the HP Virus Throttle Status and Configuration Utility. If no inconsistencies are detected in the filter driver parameters, the Status tab is displayed. The Status tab shows overall status, statistics, and delay queue information. If inconsistencies are detected, a warning message displays. Click OK.

2.Click the Configuration tab. The following parameters can be modified:

•Delay Queue Size—Controls the maximum number of delayed connection requests in the queue for each instance of the filter driver. Requests over the queue size are dropped. The default is

200delayed connection requests. The valid range is 1 through 1000.

•Delay Queue High Water Mark—Controls the number of connection requests in the delay queue at which virus-like activity is considered to be occurring for each instance of the filter driver. The default is 160 connection requests. The valid range is 1 through Delay Queue Size.

•Delay Queue Low Water Mark—Controls the number of connection requests in the delay queue below which virus-like activity is considered to be stopped. The default is 100 connection requests. The valid range is 1 through High Water Mark.

•Delay Period—Controls the rate at which connection requests are removed from the delay queue and passed down the protocol network stack. The default is 1 second. The valid range is

1through 10 seconds.

•Host Working Set Size—Controls the number of known machines to which connections are established without delay. When a new connection is made, the oldest member of the working set is replaced with the new host. The default is 5 hosts. The valid range is 1 through 100.

3.Configure the Virus Throttle parameters as necessary, and click OK.

4.Click Yes>OK when prompted.

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.
