In addition to the real-time information that you can collect on ISA Server, you should also develop a strategy to collect long-term information on ISA Server. Categories of information that you should collect include the following:

Performance-related information To prepare for future modifications to the ISA Server infrastructure, regularly collect information about ISA Server performance. As a best practice, collect information about the performance to establish a baseline and then regularly collect the same types of information to determine how the performance on ISA Server is changing. Usage information Regularly collect usage reports. This is useful for future planning and to monitor the current activity on the server. Security-related information Collect information about security-related events. This information allows you to develop a baseline of the normal security events, which makes it easier to detect an anomaly to that regular pattern. This information may also be useful to track the progress of a successful attack so that you can prevent such an attack in the future.

As part of collecting long-term information, also develop a strategy for archiving and regularly review the information. The time line for reviewing this information will depend on the types of information collected. For example, you may want to review the security-related information on a daily basis, the usage information on a weekly basis, and the performance data only once per month.

As part of your monitoring strategy, create a strategy for how to respond to critical events that occur on the ISA Server computer. These events could include:

In each case, develop a strategy for how you will detect these activities and then how you will respond when the event is detected. As part of this strategy, create an immediate-response plan, such as isolating servers or networks, or shutting down services, in the event of a security breach and a longer-term plan for investigating and mitigating the attacks.
ISA Server Performance and Service Monitoring
ISA Server 2004 uses the Microsoft Windows 2000 or Microsoft Windows Server 2003 Performance Monitor to assess server performance. When you install ISA Server

Implementing Monitoring and Reporting
Management Console on a computer, the ISA Server Performance Monitor is also installed, providing a preconfigured Performance console that includes the most important ISA Server counters. You can use this monitor to add the ISA Server counters that you want to track to the Performance Console.
Monitoring ISA Server Performance
When you install ISA Server, the installation configures several new performance objects that you can use to monitor ISA Server performance on the computer. You view the performance objects and their associated performance counters in real time in System Monitor, which is a monitoring tool that is included with Windows 2000 and Windows Server 2003. You can also log performance data and create alerts from the data by using Performance Log and Alerts. To access the ISA Server Performance Monitor, click ISA Server Performance Monitor in the Microsoft ISA Server menu on the Start menu. The Microsoft Management Console (MMC), with the preconfigured counters, is shown in Figure 11-2.

The ISA Server Performance Monitor
See Also If you are not familiar with using Performance Monitor in Windows 2000 Server or Windows Server 2003, refer to the Performance Monitoring chapter in the Server Operations Guide that is part of the Windows 2000 Server Resource Kit. The chapter is available at http://www.microsoft.com/resources/documentation/windows/2000/server/reskit/en-us/ default.asp. Although this reference deals specifically with Windows 2000 Server, the concepts and monitoring interface have not changed significantly for Windows Server 2003.

The ISA Server performance objects that are installed are listed in Table 11-3.
Table 11-3
ISA Server Performance Objects
Explanation Includes performance counters to monitor connections and throughput for the Firewall engine. Use these counters to monitor the number of client connections, the number of allowed and dropped packets, and the number of bytes passed through the Firewall engine. For example, use the Active Connections counter to monitor the number of clients currently connected to ISA Server. Includes performance counters to monitor the memory, disk, and URL activity associated with the cache. Use these performance counters to monitor the effectiveness of the cache. For example, you can use the Disk URL Retrieve Rate performance counter to determine the rate at which URLs are retrieved from the disk cache. Includes performance counters to monitor Firewall service connections and associated services such as DNS. This object monitors only Firewall client connections. For example, you can use the Active Sessions performance counter to monitor the number of Firewall client sessions that are running simultaneously. Includes counters to monitor the number of users and the rate at which ISA Server transfers data to remote and upstream servers. For example, you can use the Total Users performance counter to monitor the total number of users that are connected to the Web proxy service. Includes counters that monitor the total and the active H.323 calls on the ISA Server computer.
