You can use this document to send Cisco Adaptive Secure Appliance (ASA) logs to Armor's Security Information & Event Management (SIEM).

This document only applies to:

  • Cisco Adaptive Secure Appliance (ASA) 8.X

  • Cisco Adaptive Secure Appliance (ASA) 9.X


Pre-Deployment Considerations

...

To create a remote Log Relay, you must already have:


Update your Cisco ASA device

...

  1. Log into your Cisco ASA device.

  2. Access the privileged EXEC mode:

    Code Block
    languagebash
    hostname> enable
  3. Access the global configuration mode:

    Code Block
    languagebash
    hostname# configure terminal
  4. Enable logging:

    Code Block
    languagebash
    hostname(config)# logging enable
  5. Configure the global logging settings:

    Code Block
    languagebash
    hostname(config)# logging timestamp
    hostname(config)# logging trap warning
    hostname(config)# logging asdm warning
    hostname(config)# logging device-id hostname
  6. Configure logs to be sent to a designated Armor Log Relay device:

    Code Block
    languagebash
    hostname(config)# logging host <interface> <ipaddress> <protocol/port>
    Note
    • In <interface>, enter the name of the Cisco Adaptive Security Appliance (ASA) interface.
    • In <ipaddress>, enter the IP address of the corresponding Armor Log Relay device.
      • To locate your IP address in AMP, in the left-side navigation, click Infrastructure, click Virtual Machines, and then review the Primary IP column for the corresponding virtual machine.
    • In <protocol/port>:
      • For UDP, enter udp/10041.
        • Armor recommends that you use UDP.
      • For TCP, enter tcp/10041.
        • If you use TCP, then the ASA can determine the availability of the status of the syslog server. If the ASA cannot establish a connection to the syslog server to log activity, then by default, the ASA will not allow new connections for transit traffic. Use the following command to allow transit traffic,

          Code Block
          themeMidnight
          hostname(config)# logging permit-hostdown


  7. To ensure that the log messages use the IP address and not the object names, disable the output object name option:

    Code Block
    languagebash
    hostname(config)# no names
    
  8. Exit the configuration:

    Code Block
    languagebash
    hostname(config)# exit
  9. Save the changes:

    Code Block
    languagebash
    hostname# write memory
  10. Review the logging configuration:

    Code Block
    languagebash
    hostname# show run all logging
    logging enable
    logging timestamp
    logging hide username
    logging buffer-size 4096
    logging asdm-buffer-size 100
    logging buffered warnings
    logging trap warnings
    logging asdm warnings
    logging device-id hostname
    logging host inside 100.64.0.10 17/5140
    logging flash-minimum-free 3076
    logging flash-maximum-allocation 1024
    Note

    If present, logging standby enables logging on a standby unit with failover enabled. As a result, this option causes increases traffic on the syslog server.

Troubleshooting

Verify that logs are formatted correctly, similar to the following example:

Code Block
languagetext
themeMidnight
