Filtering Firewall Logs


Comodo Internet Security allows you to create custom views of all logged events according to user defined criteria. You can use the following types of filters:
  • Preset Time Filters
  • Advanced Filters


Preset Time Filters:


Clicking on the handle at the bottom enables you to filter the logs for a selected  time period:



 

  • Today - Displays all logged events for today.
  • Current Week - Displays all logged events during the current week. (The current week is calculated from the Sunday to Saturday that holds the current date.)
  • Current Month - Displays all logged events during the month that holds the current date.
  • Entire Period - Displays every event logged since Comodo Internet Security was installed. (If you have cleared the log history since installation, this option shows all logs created since that clearance).
  • Custom Filter – Enables you to select a custom period by choosing the 'From' and 'To' dates under 'Please Select Period'


Advanced Filters


Having chosen a preset time filter you can further refine the displayed events according to specific filters. Following are available filters for Firewall logs and their meanings:

  • Action - Displays events according to the response (or action taken) by the firewall
  • Application - Displays only the events propagated by a specific application
  • Destination IP - Displays only the events with a specific target IP address
  • Destination Port - Displays only the events with a specific target port number
  • Direction - Displays only the events of Inbound or Outbound nature
  • Protocol - Displays only the events that involved a specific protocol
  • Source IP address - Displays only the events that originated from a specific IP address
  • Source Port - Displays only the events that originated from a specific port number

To configure Advanced Filters for Firewall events

  1. Click the funnel button  from the title bar. The Advanced Filter interface for Firewall events will open.

  2. Select the filter from the 'Advanced Filter' drop-down and click 'Add' to apply the filter.




You have 8 categories of filters that you can add. Each of these categories can be further refined by either selecting or deselecting specific filter parameters or by the user typing a filter string in the field provided. You can add and configure any number of filters in the 'Advanced Filter' dialog.

Following are the options available in the 'Advanced Filter' drop-down:

  1. Action: Selecting the 'Action' option displays a drop-down box and a set of specific filter parameters that can be selected or deselected.

  2. Now select the checkboxes of the specific filter parameters to refine your search. The parameter available are:

If you select 'Does Not Contain' option from the drop-down field and enter the phrase 'bluto-force' in the text field, then all events that do not have the entry 'bluto-force' in the 'Application' column will be displayed.

  2. Select 'IPv4' or 'IPv6' from the drop-down box.

  3. Enter the destination system's IP address that needs to be filtered.

For example, if you select 'Contains' option from the drop-down field, select IPv4 and enter 192.168.111.111 in the text fields, then all events containing the entry '192.168.111.111' in the 'Destination IP' column will be displayed.

  • Not Equal
  1. Now enter the destination port number in the text entry field.
