Preparation Tasks To prepare for this module, you should:  Read all of the materials for this module.  Complete the lab.  Study the review questions and prepare alternative answers to discuss.  Anticipate questions that students may ask. Write out the questions and provide the answers.  Read “Configure Monitoring and Reporting,” “Monitoring and Reporting,” “Event Messages,” and “Performance Counters” in ISA Server Help.  Read Module 8, "Monitoring and Optimizing Performance in Windows 2000," in Course 2152B, Implementing Microsoft Windows ® 2000 Professional and Server.  Review the \sdk\bin\isasdk.chm file on the ISA Server compact disc. Presentation: 45 Minutes Lab: 30 Minutes iv Module 8: Monitoring and Reporting Instructor Setup for Lab Lab A: Monitoring and Reporting  To prepare for the lab: 1. Open a command prompt window. 2. At the command prompt, type cd C:\MOC\2159a\Labfiles\Lab8 3. When a student asks you during the lab to perform a simulated port scan attack, type portscan ip_address (where ip_address is the IP address of the student’s ISA Server computer on the classroom network), and then press ENTER. Module 8: Monitoring and Reporting v Module Strategy Use the following strategy to present this module:  Planning a Monitoring and Reporting Strategy Begin the module by describing the guidelines to consider when planning a monitoring and reporting strategy.  Monitoring Intrusion Detection When describing the different types of network intrusion, do not explain each attack in detail, but use one or two of them as examples. Emphasize that although ISA Server generates events when an intrusion attack occurs, ISA Server generates alerts only if you specifically configure ISA Server to do so. Do not cover all of the ISA Server events in detail. Instead, refer students to ISA Server Help for more information about specific events.  Monitoring ISA Server Activity Explain that logging to a database can centralize ISA Server logs and secure the log data. Emphasize that logging both allowed packets and blocked packets can cause a considerable load on the server and that you should enable logging for allowed packets for diagnostic purposes only.  Analyzing ISA Server Activity by Using Reports Explain that ISA Server reports require summaries of saved logs and that you can create an ISA Server report only after ISA Server has created at least one daily summary. Emphasize that if a server belongs to a multi- server array, the administrator generating the reports must have the appropriate permissions on each ISA Server computer in the array. Briefly display an example of each report format to illustrate the contents of the reports.  Monitoring Real-Time Activity Explain that the ISA Server real-time monitoring feature enables you to centrally monitor ISA Server computer activity, including the current sessions. Point out the ISA Server Performance Monitor on the Microsoft ISA Server menu.  Testing the ISA Server Configuration Explain that after configuring ISA Server, it is recommended that you test your configuration to ensure that ISA Server correctly enforces the security settings. Explain that you can use a third-party intrusion detection system or the applications that are included with Windows 2000 to test the ISA Server configuration. vi Module 8: Monitoring and Reporting Customization Information This section identifies the lab setup requirements for a module and the configuration changes that occur on student computers during the labs. This information is provided to assist you in replicating or customizing Microsoft Official Curriculum (MOC) courseware. The lab in this module is also dependent on the classroom configuration that is specified in the Customization Information section at the end of the Classroom Setup Guide for Course 2159A, Deploying and Managing Microsoft Internet Security and Acceleration Server 2000.

Module 8: Monitoring and Reporting 1 Overview  Planning a Monitoring and Reporting Strategy  Monitoring Intrusion Detection  Monitoring ISA Server Activity  Analyzing ISA Server Activity by Using Reports  Monitoring Real-Time Activity  Testing the ISA Server Configuration ***************************** ILLEGAL FOR NON - TRAINER USE ****************************** Without a monitoring and reporting strategy in place for a Microsoft ® Internet Security and Acceleration (ISA) Server 2000 computer, network administrators may be unaware of important events or trends, be confronted with a profusion of false alerts, or configure logs and reports that do not monitor the appropriate activities. By using alerts, logs, reports, and real-time monitoring effectively, network administrators can better manage the activities that can compromise the security or the performance of an ISA Server computer. In addition, network administrators can use specialized assessment tools to monitor network security. After completing this module, you will be able to:  Plan a strategy for monitoring and reporting ISA Server activities.  Configure alerts to monitor intrusion detection.  Configure logging to monitor ISA Server activity.  Use reports to analyze ISA Server activity.  Monitor ISA Server computer activity.  Test the ISA Server configuration. Topic Objective To provide an overview of the module topics and objectives. Lead-in In this module, you will learn about monitoring ISA Server activities by using alerts, logging, reporting, and real- time monitoring. 2 Module 8: Monitoring and Reporting Planning a Monitoring and Reporting Strategy Categorize the information that you need to collect Categorize the information that you need to collect Determine what information is most critical Determine what information is most critical Document your strategy Document your strategy Create a schedule for regular review of logs Create a schedule for regular review of logs Design a plan for archiving logs Design a plan for archiving logs Create a strategy for how to respond to critical events Create a strategy for how to respond to critical events ***************************** ILLEGAL FOR NON - TRAINER USE ****************************** Consider the following guidelines when you plan a monitoring and reporting strategy:  Categorize the information that you need to collect, including the following items: • Real-time alerts • Trends of performance • Trends of security-related events  Determine the information that is the most critical, and then: • Configure real-time alerting for only the most critical issues. • Review the logs frequently for events that may signal serious issues and that may require prompt, but not immediate, attention. • Review all of the logs for important trends. Ensure that your summary reports capture the information that is the most important to you.  Document your strategy.  Create a strategy for how to respond to critical events, such as: • Network security breaches. • Denial of services attacks. • Unusual usage patterns.  Create a schedule for regular review of the logs.  Design a plan for archiving the logs. • You can use archived logs to discover trends, to investigate the source of future alerts, or for legal purposes.
