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:

...

• A Log Relay server on your account

  • To learn how to add Log Relay to your account, see Obtain Log Relay for Remote Log Collection

• Configured the system clock

Update your Cisco ASA device

...

1. Log into your Cisco ASA device.

2. Access the privileged EXEC mode:

   Code Block
   language bash
   hostname> enable

3. Access the global configuration mode:

   Code Block
   language bash
   hostname# configure terminal

4. Enable logging:

   Code Block
   language bash
   hostname(config)# logging enable

5. Configure the global logging settings:

   Code Block
   language bash
   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
   language bash
   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 theme Midnight 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
   language bash
   hostname(config)# no names

8. Exit the configuration:

   Code Block
   language bash
   hostname(config)# exit

9. Save the changes:

   Code Block
   language bash
   hostname# write memory

10. Review the logging configuration:
    

    Code Block
    language bash
    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.
