v9.6.5 Release Notes for Cyfin

Enhancements

  • Health
    • Added new Health status page to display the current state of different components in the product through Health Modules. These modules can be configured to trigger notification alert emails when an error is detected. The following modules are currently available:
      • License Expiration – Checks the number of days left on the license and can trigger warning and error notifications based on days left.
      • Syslog Inactivity – Checks active syslog ports for data being sent and triggers alert when no data is received in a configurable time period. Module also checks for valid data being received instead of just any data and triggers different error alert accordingly.
  • Reporting
    • Dashboard
      • Visualizer
        • Added an extensive library of preconfigured charts for users to select when creating new panels.
  • Library
    • Updated product to use most recent MySQL library (8.0.33).

Corrections

Configuring Data Sources

In Cyfin version 9.3.1, the Log Data Source Setup wizard has been redesigned to improve the configuration of the product to locate and read your Web-use data when it is syslog data, log files, or database logs. The system will analyze your data to detect the data source format and present the most suitable data types. This allows you to select the best data type from the list and ensures that you get the best match available.

You will be able to select from the following data sources: syslog, directory-based, and database.

For syslog data, select the Internet protocol you want to use, and enter the listening port number. Click Test to start collecting data. If this is successful, you will see the number of messages received incrementing. Click Stop and then Next to continue.

For directory-based or log file data, specify the directory location of your data files. You can also enter a file name with an asterisk to filter your log files, e.g., proxy*.txt. Click Test to display the number of files found. Click Next.

The Data Source Type page is displayed.

The Type of Data drop-down field will display multiple matches. As you select a data type, the data format will be shown in the Data Preview box. Look closely at the data fields to ensure that they are correct or complete.

  • You may see incomplete data, for example, if you were expecting a user name and it is missing. Click Reanalyze to see another record sample.
  • If you need to refresh the data for any reason or are still in the process of receiving syslog messages, click Reanalyze and then select the data source type again.
  • If your firewall is not in the drop-down field, but the data of another completely matches and is in the correct columns, you may select that firewall even though it has a different name. Some firewalls share common data formats.
  • If no matches are found, all syslog and directory data types will become available in the drop-down field. You can select a different data type from the field to complete the configuration process and return at a later time to change it.
  • It is easy to add new data sources to our extensive library. If you have a new data source, need assistance with multiple matches, or have no matching files, just contact Technical Support.

Also for Syslog, you can specify a location in which to keep a local copy of your data.

For database data, the system loads and populates the Type field with database data types. The “More info” link provides setup information on your specific database. Select the type of database and complete the remaining fields. Some fields will be populated with default values.

The last step is to give the data source configuration a name. This is helpful for identification purposes, especially if you add more data source configurations later.

If you have any questions, please contact Technical Support at (321) 953-5351, Ext. 4 or support@wavecrest.net.

Configuring Zscaler for Cyfin Syslog

Configuring Cisco Firepower logs for Cyfin Syslog

The following steps pertain to Cisco Firepower Threat Defense and are required to forward these logs to Cyfin Syslog Server:

  1. Select Devices – Platform Settings and create or edit a Firepower Threat Defense policy.
  2. Select Syslog – Syslog Server.
  3. Check the Allow user traffic to pass when TCP syslog server is down check box to allow traffic if any syslog server that is using the TCP protocol is down.
  4. Enter a size of the queue for storing syslog messages on the security appliance when syslog server is busy in the Message queue size (messages) field. The minimum is 1 message. The default is 512. Specify 0 to allow an unlimited number of messages to be queued (subject to available block memory).
  5. Click Add to add a new syslog server.
    • In the IP Address drop-down list, select a network host object that contains the IP address of the syslog server.
    • Choose the protocol (either TCP or UDP) and enter the port number for communications between the Firepower Threat Defense device and Cyfin syslog server.
    • The default ports are 514 for UDP and 1470 for TCP. Valid nondefault port values for either protocol are 1025 through 65535.
    • Check the Log messages in Cisco EMBLEM format (UDP only) check box to specify whether to log messages in Cisco EMBLEM format (available only if UDP is selected as the protocol).
    • Add the zones that contain the interfaces used to communicate with the syslog server. For interfaces not in a zone, you can type the interface name into the field below the Selected Zones/Interface list and click Add. These rules will be applied to a device only if the device includes the selected interfaces or zones.

    Note:  If the syslog server is on the network attached to the physical Management interface, you must type the name of that interface into the Interface Name field below the Selected Security Zones list and click Add. You must also configure this name (if not already configured), and an IP address, for the Diagnostic interface (edit the device from the Device Management page and select the Interfaces tab).

    • Click OK.
  1. Click Save.

You can now click Deploy and deploy the policy to assigned devices. The changes are not active until you deploy them.

Check Point Log Exporter

If you are running Check Point R77.30 or later, you must first use Check Point Log Exporter for exporting Check Point logs over syslog to Cyfin. Click here for the instructions from Check Point Support.

Important Notes

Commands should be run in an SSH session switched to Expert mode.

Installation

Ensure that the Log Exporter is installed on a log server for Check Point R77.30 and R80.10. Log Exporter is already integrated in R80.20.

Basic Deployment

In order to configure a Cyfin target for the logs, run the following on the log server:

cp_log_export add name cyfin_syslog target-server <cyfin_ip> target-port 1455 protocol udp format syslog –apply-now

where <cyfin_ip> is the IP address of your Cyfin server

Helpful Tools

  • To remove the exporter, run:

cp_log_export delete name cyfin_syslog –apply-now

  • To display the exporter’s status, run:

cp_log_export status name cyfin_syslog

  • To reset the current position and reexport all logs per the configuration, run:

cp_log_export reexport name cyfin_syslog

Troubleshooting Tips

If you do not see log files being exported:

  • Stop the exporter by running: cpstop
  • Then start the exporter by running: cpstart

If there is still an issue:

  • Edit $EXPORTERDIR/targets/cyfin_syslog/targetConfiguration.xml
  • Locate <log_files>1</log_files>
  • Change to <log_files></log_files>
  • Stop the exporter by running: cpstop
  • Then start the exporter by running: cpstart

Once this part is completed in Check Point, you can then open Cyfin, go to Data Management – Log Data Source – Setup, and run through the Log Data Source Setup wizard. Upon completing the Log Data Source Setup wizard, you should start to see data in the file “SyslogXXXXXXX.txt” in the log file directory that you chose in the wizard.
