The Manage Banned Hashes page lets you add, manage, and get information about process hash bans created on your Carbon Black EDR server.

  • Table of Bans – Any hash bans that have been created on your Carbon Black EDR server are listed in a table, including bans that are enabled and bans that are not currently enabled. An indicator at the top-right corner of the page shows the total number of bans (both enabled and disabled) that have been created.

  • Access to Additional Ban Information – Some information about each ban is shown in the table rows, and additional information is available through drill-down features for each ban.

  • Toggling of Ban Status – The status of each ban is displayed in the Banned column. You can enable or disable any ban.

  • Ban More Hashes – This button opens the Add Hashes to Ban List dialog, where you can enter one or more hash values to create new bans.

The table of hashes lists each hash that has been created on this server. You can also search for hash bans by the MD5 hash of the process, and you can control the display of the entire table using the following controls:

  • View – You can click different buttons in the View field to display All bans (the default), currently Banned hashes, and Previously Banned hashes (ban disabled).

  • Sort By – You can sort the table by MD5 hash (default), Date Added , or User. Radio buttons change the sort order from ascending to descending.

The following table describes fields on this page. The table data that reports on blocks caused by bans requires that the Banning Events feed on the Threat Intelligence Feeds page is enabled. (See Threat Intelligence Feeds.)
