Conventions LogLogic documentation uses the following conventions to highlight code and command-line elements: A monospace font is used for programming elements (such as code fragments, objects, methods, parameters, and HTML tags) and system elements (such as filenames, directories, paths, and URLs). A monospace bold font is used to distinguish system prompts or screen output from user responses, as in this example: username: system home directory: home\app A monospace italic font is used for placeholders, which are general names that you replace with names specific to your site, as in this example: LogLogic_home_directory\upgrade\ Straight brackets signal options in command-line syntax. For example: ls [-AabCcdFfgiLlmnopqRrstux1] [-X attr] [path...] 6 Cisco IPS Log Configuration Guide
Chapter 1 Configuring LogLogic s Cisco IPS Log Collection This chapter describes the configuration steps involved to enable a LogLogic Appliance to request Cisco IPS logs. The configuration steps assume that you have a functioning LogLogic Appliance that can be configured to capture Cisco IPS-related log data. Introduction to Cisco IPS.................................................... 7 Prerequisites............................................................. 7 Enabling a Cisco IPS for SDEE............................................... 7 Enabling the LogLogic Appliance to Capture Data................................ 8 Verifying the Configuration................................................... 9 Introduction to Cisco IPS The LogLogic Appliance support for the Cisco IPS Alert events is now available. The Cisco IPS signature library will consist of specific signatures enabled with logging. Prerequisites Prior to configuring Cisco IPS and the LogLogic Appliance, ensure that you meet the following prerequisites: Cisco IPS version 6.2 and 7.0 Proper access permissions to make configuration changes LogLogic Appliance running Release 4.9.1 or later with a Log Source Package that includes Cisco IPS support Administrative access on the LogLogic Appliance Enabling a Cisco IPS for SDEE You must configure the Cisco IPS to allow connections to SDEE prior to configuring the LogLogic Appliance. Note: This document does not describe all features and functionality within Cisco IPS regarding configuration. For more information on these areas, see Cisco IPS Product Documentation. To configure the Cisco IPS to allow connections to SDEE: 1. Launch a web browser. 2. Specify the IP address of the Cisco IDM sensor in the Address field. 3. If the dialog box shown, click on OK. Cisco IPS Log Configuration Guide 7
4. At the Prompt dialog, enter your username and password, and click OK. 5. On the left-most panel, select Sensor Setup Allowed Hosts. The Cisco IDM window displays the Allowed Hosts panel. 6. Add the IP address and Network Mask of the LogLogic Appliance. 7. Click Apply. The LogLogic Appliance will now be able to connect to the Cisco SDEE sensor. Note: TLS/SSL must be enabled and the Web Server Port must be set to 443 under Configuration > Sensor Setup > Network, Web Server Settings. Enabling the LogLogic Appliance to Capture Data The following sections describe how to enable the LogLogic Appliance to capture Cisco IPS SDEE log data. Adding a Cisco IPS Device If you do not want to utilize the auto-identification feature, you can manually add a Cisco IPS device to the LogLogic Appliance before you redirect the logs. To add Cisco IPS as a new device: 1. Log in to the LogLogic Appliance. 2. From the navigation menu, select Management > Devices. The Devices tab appears. 3. Click Add New. The Add Device tab appears. 4. Type in the following information for the device: Name Name for the Cisco IPS device Description (optional) Description of the Cisco IPS device Device Type Select Cisco IPS from the drop-down menu Host IP IP address of the Cisco IPS appliance Enable Data Collection Select the Yes radio button Refresh Device Name through DNS Lookups (optional) Select this checkbox to enable the Name field to be automatically updated. The name is obtained using a reverse DNS lookup on the configured refresh interval. The DNS name overrides any manual name you assign. SSL Port Cisco IPS Sensor SDEE port Polling Interval Collection Polling Interval UserID User name of account on Cisco IPS Sensor Password Password for User account 5. In the Cisco IPS Collector Configuration panel, enter a UserID and a Password, then click Test Connection to ensure that the connection does work. 6. Click Add. 8 Cisco IPS Log Configuration Guide
Figure 1 Add Device Tab 7. Verify that your new device appears in the Devices tab and that Enabled is set to Yes. When the logs arrive from the specified Cisco IPS appliance, the LogLogic Appliance uses the device you just added if the hostname or IP match. Verifying the Configuration The section describes how to verify that the configuration changes made to Cisco IPS and the LogLogic Appliance are applied correctly. To verify the configuration: 1. Log in to the LogLogic Appliance. 2. From the navigation menu, select Dashboards > Log Source Status. 3. Locate the IP address for each Cisco IPS device. If the device name (Cisco IPS) appears in the list of devices, then the configuration is correct (Figure 2). Cisco IPS Log Configuration Guide 9
Figure 2 Verification of the Cisco IPS Configuration If the device does not appear in the Log Source Status tab, check the Cisco IPS logs to identify if any events are being generated. If events were detected, but are still not appearing on the LogLogic Appliance, please verify the Cisco IPS configuration and the LogLogic Appliance configuration. 10 Cisco IPS Log Configuration Guide
Chapter 2 How LogLogic Supports Cisco IPS This chapter describes LogLogic s support for Cisco IPS. LogLogic enables you to capture Cisco IPS log data to monitor events. LogLogic supports Cisco IPS logs. How LogLogic Captures Cisco IPS Data....................................... 11 LogLogic Real-Time Reports................................................ 11 How LogLogic Captures Cisco IPS Data Cisco IPS posts events using the SDEE (Security Device Event Exchange) format and protocol over SSL for the LogLogic Appliance to retrieve. Once the data is captured you can generate search reports or create alerts. For more information on creating reports and alerts, see the LogLogic Users Guide and LogLogic Online Help. Figure 3 Cisco IPS, SDEE, and Loglogic Architecture LogLogic Real-Time Reports LogLogic provides pre-configured Real-Time Reports for log data. The following Real-Time Reports are available: All Unparsed Events Displays data for all events retrieved from the Microsoft Windows log for a specified time interval IDS/IPS Activity - Displays Source and Destination IP address, Destination port number, and Signature intrusion detection information for a specified time interval. To access LMI 5 Real-Time Reports: 1. In the top navigation pane, click Reports. Cisco IPS Log Configuration Guide 11
2. Click Threat Management. The following Real-Time Reports are available: IDS/IPS Activity 3. Click Operational. The following Real-Time Reports are available: All Unparsed Events You can create custom reports from the existing Real-Time Report templates. For more information, see the LogLogic User Guide and LogLogic Online Help. 12 Cisco IPS Log Configuration Guide
Appendix A Event Reference This appendix lists the LogLogic-supported Cisco IPS events. The LogLogic Cisco IPS event table identifies event formats that can be analyzed through LogLogic Agile Reports, as well as a sample log message. LogLogic Support for Cisco IPS Events The following list describes the contents of each of the columns in the table below. Event ID Refers to an ID referencing the unique occurrence. Agile Reports/Search Defines whether the Cisco IPS event is available through the LogLogic Agile Reporting engine or through the search capabilities. If the event is available through the Agile Report engine, then you can use LogLogic Real-Time Reports and Summary Reports to analyze and display the captured log data. Otherwise, all other supported events that are captured by the LogLogic Appliance can be viewed by performing a search for the log data. Title Not Applicable (N/A). Event Category Category of event, such as Alert, System, Error. Event Type Type of event Traffic. Sample Log Message Sample Cisco IPS log messages. LogLogic supports all "evidsalert" eventtype, if enabled to log on the Cisco IPS device. These events are supported by the IDS Activity report.
