[SIEM][Exceptions] - Cleaned up and updated exception list item comment structure (#69532)
### Summary

This PR is a follow up to #68864 . That PR used a partial to differentiate between new and existing comments, this meant that comments could be updated when they shouldn't. It was decided in our discussion of exception list schemas that comments should be append only. This PR assures that's the case, but also leaves it open to editing comments (via API). It checks to make sure that users can only update their own comments.

README.md for developers working on the backend lists on how to get started using the CURL scripts in the scripts folder.

The scripts rely on CURL and jq:

Install curl and jq (mac instructions)

brew update
brew install curl
brew install jq

Open $HOME/.zshrc or ${HOME}.bashrc depending on your SHELL output from echo $SHELL and add these environment variables:

export ELASTICSEARCH_USERNAME=${user}
export ELASTICSEARCH_PASSWORD=${password}
export ELASTICSEARCH_URL=https://${ip}:9200
export KIBANA_URL=http://localhost:5601
export TASK_MANAGER_INDEX=.kibana-task-manager-${your user id}
export KIBANA_INDEX=.kibana-${your user id}

source $HOME/.zshrc or ${HOME}.bashrc to ensure variables are set:

source ~/.zshrc

Open your kibana.dev.yml file and add these lines:

# Enable lists feature
xpack.lists.enabled: true
xpack.lists.listIndex: '.lists-frank'
xpack.lists.listItemIndex: '.items-frank'

Restart Kibana and ensure that you are using --no-base-path as changing the base path is a feature but will get in the way of the CURL scripts written as is.

Go to the scripts folder cd kibana/x-pack/plugins/lists/server/scripts and run:

./hard_reset.sh
./post_list.sh

which will:

  • Delete any existing lists you have
  • Delete any existing list items you have
  • Delete any existing exception lists you have
  • Delete any existing exception list items you have
  • Delete any existing mapping, policies, and templates, you might have previously had.
  • Add the latest list and list item index and its mappings using your settings from kibana.dev.yml environment variable of xpack.lists.listIndex and xpack.lists.listItemIndex.
  • Posts the sample list from ./lists/new/list_ip.json

Now you can run

./post_list.sh

You should see the new list created like so:

{
  "id": "list-ip",
  "created_at": "2020-05-28T19:15:22.344Z",
  "created_by": "yo",
  "description": "This list describes bad internet ip",
  "name": "Simple list with an ip",
  "tie_breaker_id": "c57efbc4-4977-4a32-995f-cfd296bed521",
  "type": "ip",
  "updated_at": "2020-05-28T19:15:22.344Z",
  "updated_by": "yo"
}

You can add a list item like so:

 ./post_list_item.sh

You should see the new list item created and attached to the above list like so:

{
  "id": "hand_inserted_item_id",
  "type": "ip",
  "value": "127.0.0.1",
  "created_at": "2020-05-28T19:15:49.790Z",
  "created_by": "yo",
  "list_id": "list-ip",
  "tie_breaker_id": "a881bf2e-1e17-4592-bba8-d567cb07d234",
  "updated_at": "2020-05-28T19:15:49.790Z",
  "updated_by": "yo"
}

If you want to post an exception list it would be like so:

./post_exception_list.sh

You should see the new exception list created like so:

{
  "_tags": [
    "endpoint",
    "process",
    "malware",
    "os:linux"
  ],
  "created_at": "2020-05-28T19:16:31.052Z",
  "created_by": "yo",
  "description": "This is a sample endpoint type exception",
  "id": "bcb94680-a117-11ea-ad9d-c71f4820e65b",
  "list_id": "endpoint_list",
  "name": "Sample Endpoint Exception List",
  "namespace_type": "single",
  "tags": [
    "user added string for a tag",
    "malware"
  ],
  "tie_breaker_id": "86e08c8c-c970-4b08-a6e2-cdba7bb4e023",
  "type": "endpoint",
  "updated_at": "2020-05-28T19:16:31.080Z",
  "updated_by": "yo"
}

And you can attach exception list items like so:

{
  "_tags": [
    "endpoint",
    "process",
    "malware",
    "os:linux"
  ],
  "comments": [],
  "created_at": "2020-05-28T19:17:21.099Z",
  "created_by": "yo",
  "description": "This is a sample endpoint type exception",
  "entries": [
    {
      "field": "actingProcess.file.signer",
      "operator": "included",
      "type": "match",
      "value": "Elastic, N.V."
    },
    {
      "field": "event.category",
      "operator": "included",
      "type": "match_any",
      "value": [
        "process",
        "malware"
      ]
    }
  ],
  "id": "da8d3b30-a117-11ea-ad9d-c71f4820e65b",
  "item_id": "endpoint_list_item",
  "list_id": "endpoint_list",
  "name": "Sample Endpoint Exception List",
  "namespace_type": "single",
  "tags": [
    "user added string for a tag",
    "malware"
  ],
  "tie_breaker_id": "21f84703-9476-4af8-a212-aad31e18dcb9",
  "type": "simple",
  "updated_at": "2020-05-28T19:17:21.123Z",
  "updated_by": "yo"
}

You can then do find for each one like so:

./find_lists.sh
{
  "cursor": "WzIwLFsiYzU3ZWZiYzQtNDk3Ny00YTMyLTk5NWYtY2ZkMjk2YmVkNTIxIl1d",
  "data": [
    {
      "id": "list-ip",
      "created_at": "2020-05-28T19:15:22.344Z",
      "created_by": "yo",
      "description": "This list describes bad internet ip",
      "name": "Simple list with an ip",
      "tie_breaker_id": "c57efbc4-4977-4a32-995f-cfd296bed521",
      "type": "ip",
      "updated_at": "2020-05-28T19:15:22.344Z",
      "updated_by": "yo"
    }
  ],
  "page": 1,
  "per_page": 20,
  "total": 1
}

or for finding exception lists:

./find_exception_lists.sh
{
  "data": [
    {
      "_tags": [
        "endpoint",
        "process",
        "malware",
        "os:linux"
      ],
      "created_at": "2020-05-28T19:16:31.052Z",
      "created_by": "yo",
      "description": "This is a sample endpoint type exception",
      "id": "bcb94680-a117-11ea-ad9d-c71f4820e65b",
      "list_id": "endpoint_list",
      "name": "Sample Endpoint Exception List",
      "namespace_type": "single",
      "tags": [
        "user added string for a tag",
        "malware"
      ],
      "tie_breaker_id": "86e08c8c-c970-4b08-a6e2-cdba7bb4e023",
      "type": "endpoint",
      "updated_at": "2020-05-28T19:16:31.080Z",
      "updated_by": "yo"
    }
  ],
  "page": 1,
  "per_page": 20,
  "total": 1
}
