+
+coming[8.2.0]
+
+The blocklist allows you to prevent specified applications from running on hosts, extending the list of processes that {endpoint-sec} considers malicious. This is especially useful for ensuring that known malicious processes aren't accidentally executed by end users. 
+
+[NOTE] 
+=====
+In addition to configuring specific entries on the **Blocklist** page, you must also ensure that the blocklist is enabled on the {endpoint-sec} integration policy in the <<malware-protection, Malware protection settings>>. This setting is enabled by default.
+
+You must have the built-in `superuser` role to access the blocklist. For more information, refer to {ref}/built-in-users.html[Built-in users].
+=====
+
+By default, a blocklist entry is recognized globally across all hosts running {endpoint-sec}. If you have a https://www.elastic.co/pricing[Platinum or Enterprise subscription], you can also assign a blocklist entry to specific {endpoint-sec} integration policies, which blocks the process only on hosts assigned to that policy.
+
+. Go to **Manage** -> **Blocklist**.
+
+. Click **Add blocklist entry**. The **Add blocklist** flyout appears.
+
+. Fill in these fields in the **Details** section:
+.. `Name`: Enter a name to identify the application in the blocklist.
+.. `Description`: Enter a description to provide more information on the blocklist entry (optional).
+
+. In the **Conditions** section, enter the following information about the application you want to block:
+.. `Select operating system`: Select the appropriate operating system from the drop-down.
+.. `Field`: Select a field to identify the application being blocked:
+  * `Hash`: The MD5, SHA-1, or SHA-256 hash value of the application's executable.
+  * `Path`: The full file path of the application's executable.
+  * `Signature`: (Windows only) The name of the application's digital signer.
++
+TIP: To find the signer's name for an application, go to *Kibana* -> *Discover* and query the process name of the application's executable (for example, `process.name : "mctray.exe"` for a McAfee security binary). Then, search the results for the `process.code_signature.subject_name` field, which contains the signer's name (for example, `McAfee, Inc.`).
+
+.. `Operator`: The operator is `is one of` and cannot be modified.
+
+.. `Value`: Enter the hash value, file path, or signer name. To enter multiple values (such as a list of known malicious hash values), you can enter each value individually or paste a comma-delimited list, then press **Return**.
++
+NOTE: Hash values must be valid to add them to the blocklist.
+
+. Select an option in the *Assignment* section to assign the blocklist entry to a specific integration policy:
++
+* `Global`: Assign the blocklist entry to all {endpoint-sec} integration policies.
+* `Per Policy`: Assign the blocklist entry to one or more specific {endpoint-sec} integration policies. Select each policy where you want the blocklist entry to apply.
++
+NOTE: You can also select the `Per Policy` option without immediately assigning a policy to the blocklist entry. For example, you could do this to create and review your blocklist configurations before putting them into action with a policy.
+
+. Click **Add blocklist**. The new entry is added to the **Blocklist** page.
+
+. When you're done adding entries to the blocklist, ensure that the blocklist is enabled for the {endpoint-sec} integration policies that you just assigned:
+.. Go to **Manage** -> **Policies**, then click on an integration policy.
+.. On the **Policy settings** tab, ensure that the **Malware protections enabled** and **Blocklist enabled** toggles are switched on. Both settings are enabled by default.

+[[edit-blocklist-entry]]
+=== Edit a blocklist entry
+You can individually modify each blocklist entry. With a Platinum or Enterprise subscription, you can also change the policies that a blocklist entry is assigned to.
+
+To edit a blocklist entry:
+
+. Click the actions menu (*...*​) for the blocklist entry you want to edit, then select *Edit blocklist*.
+. Modify details as needed.
+. Click *Save*.
+
+[discrete]
+[[delete-blocklist-entry]]
+=== Delete a blocklist entry
+You can delete a blocklist entry, which removes it entirely from all {endpoint-sec} policies. This allows end users to access the application that was previously blocked.
+
+To delete a blocklist entry:
+
+. Click the actions menu (*...*) for the blocklist entry you want to delete, then select *Delete blocklist*.
+. On the dialog that opens, verify that you are removing the correct blocklist entry, then click *Delete*. A confirmation message displays.
