Searching in connection content

You can search in the contents of individual connections at the api/audit/sessions/<session-id>/content/?q=<my-search-expression> endpoint.

URL
GET https://<IP-address-of-Safeguard for Privileged Sessions>/api/audit/sessions/<session-id>/content/?q=<my-search-expression>
Headers
Header name Description Required Values
session_id Contains the authentication token of the user Required

The value of the session ID cookie received from the REST server in the authentication response, for example, a1f71d030e657634730b9e887cb59a5e56162860. For details on authentication, see Authenticate to the Safeguard for Privileged Sessions REST API.

Note that this session ID refers to the connection between the REST client and the Safeguard for Privileged Sessions REST API. It is not related to the sessions that Safeguard for Privileged Sessions records (and which also have a session ID, but in a different format).

Sample request

The following command retrieves those events in the contents of a specific connection that match the search expression(s).

curl --cookie cookies https://<IP-address-of-Safeguard for Privileged Sessions>/api/audit/sessions/<session-id>/content/?q=<my-search-expression>

NOTE:

Make sure that you use the ?q option and that when you use it, you do not leave it empty. Not using the ?q option or an empty ?q will result in an empty "items" list returned in the response.

You can use the Apache Lucene query syntax to create the search expression, but note the following points.

  • You must format the search expression as a URL, and escape special characters accordingly. For example, if your search expression is man iptables, you must escape the whitespace: man%20iptables

  • Do not begin the expression with the * wildcard.

Response

The response contains a list of those events in the contents of the connection that match the search expression(s). The response also contains some meta fields.

If you specified a search expression using the ?q option and the response returns an empty "items" list, that can indicate that:

  • The search returned no results.

  • There is no content recorded for the connection.

The following is an example response:

{
    "items": [
        { 
            "psm.channel.id": 5, 
            "end_time": "2017-08-14T10:35:43.957000",

Session statistics

The api/audit/sessions/stats endpoint provides statistics about recorded sessions (active and closed).

URL
GET https://<IP-address-of-Safeguard for Privileged Sessions>/api/audit/sessions/stats?field=<field-name>
Headers
Header name Description Required Values
session_id Contains the authentication token of the user Required

The value of the session ID cookie received from the REST server in the authentication response, for example, a1f71d030e657634730b9e887cb59a5e56162860. For details on authentication, see Authenticate to the Safeguard for Privileged Sessions REST API.

Note that this session ID refers to the connection between the REST client and the Safeguard for Privileged Sessions REST API. It is not related to the sessions that Safeguard for Privileged Sessions records (and which also have a session ID, but in a different format).

Sample request

The following command retrieves statistical data about sessions.

curl --cookie cookies https://<IP-address-of-Safeguard for Privileged Sessions>/api/audit/sessions/stats?field=<field-name>
Request parameters

Use the following parameters to fine-tune your request for statistics:

  • ?q: Narrow down the scope of statistics using one or more properties (elements) of the sessions.

  • ?field: Request statistics for the selected properties (elements and values) of sessions (for example, protocol).

    Using this parameter is mandatory.

  • ?size: Limit the range of values displayed in the statistics for a given field. Statistics will be shown only for the top size number of most frequently occurring values (that is, values with the highest number of counts).

    Take the following example. If you query "/api/audit/sessions/stats?field=protocol&size=2", and the following sessions were recorded:

    ...
    {
      "Alpha": {
        "protocol": "http"
      },
      "Bravo": {
        "protocol": "ssh"
      },
      "Charlie": {
        "protocol": "rdp"
      },
      "Delta": {
        "protocol": "rdp"
      },
      "Echo": {
        "protocol": "rdp"
      },
      "Foxtrot": {
        "protocol": "http"
      },
      "Golf": {
        "protocol": "http"
      }
    }
    ...

    The response contains:

    ...
    {
     "meta": {
        "href": "/api/audit/sessions/stats",
        "parent": "/api/audit/sessions",
        "others": 1,
        "field": "protocol",
        "size": 2
     }
    }
    ...

    And the response items look like the snippet below. That is, in this example, there will be no statistics for "protocol": "ssh". The top 2 values are "rdp" and "http", with a count of 3 each. "ssh" occurred only once, so it did not make it to the top 2 most frequent values.

    ...
    [
     {"count": 3, "value": "http"},
     {"count": 3, "value": "rdp"}
    ...
  • ?start: Statistics are returned for sessions that started after the specified date. Use the ISO 8601 format for the date, for example, 2017-01-25T10:00.

  • ?end: Statistics are returned for sessions that ended before the specified date. Use the ISO 8601 format for the date, for example, 2017-01-25T11:00.

  • ?content: Statistics are returned for indexed sessions that contain the type of content specified.

    NOTE:

    When performing a content query, the maximum number of results returned is 3000. When this limit is exceeded, the scope of statistics is limited to the first 3000 sessions (even if there are more than 3000 sessions that match your criteria).

Response

The following snippet is a sample response received when retrieving statistics about the protocol field. For details of the meta object, see Introduction. Those fields of the meta object that are specific to statistics are collected in table Session statistics.

{
    "items": [
        {
            "count": 7,
            "value": "ssh"
        }
    ],
    "meta": {
        "field": "protocol",
        "href": "/api/audit/sessions/stats",
        "others": 0,
        "parent": "/api/audit/sessions",
        "remaining_seconds": 600,
        "size": 10
    }
}
Element Type Description
body, or items when a list is returned Top-level element (string) Contains the properties that are in the scope of the requested statistics.
count integer Indicates the number of sessions included in the scope of statistics.
value string Contains the value of the field that you requested statistics about.
meta Top-level element Contains links to different parts of the REST service.
field string Contains the name of the field that you requested statistics about.
others integer

Some values of the field that you specified in your query are not included in the scope of statitics. This happens when a specific value occurs fewer times in the examined sessions than the aggregation size.

The others field indicates the number of those distinct values that are not included in the statistics.

For a detailed explanation with an example, see Session statistics.

size integer The size that you specified in your query.

Status and error codes

The following table lists typical status and error codes for the statistics request. For a complete list of error codes, see Using the Safeguard for Privileged Sessions REST API.

Code Description Notes
200 OK The query was well-formed and statistics have been successfully retrieved.
400 InvalidQueryValue The query is invalid, for example, it has an invalid value.
500 SearchUnavailable The search backend is inaccessible.

Session histogram

The api/audit/sessions/histogram endpoint provides a histogram about the recorded sessions.

URL
GET https://<IP-address-of-Safeguard for Privileged Sessions>/api/audit/sessions/histogram
Headers
Header name Description Required Values
session_id Contains the authentication token of the user Required

The value of the session ID cookie received from the REST server in the authentication response, for example, a1f71d030e657634730b9e887cb59a5e56162860. For details on authentication, see Authenticate to the Safeguard for Privileged Sessions REST API.

Note that this session ID refers to the connection between the REST client and the Safeguard for Privileged Sessions REST API. It is not related to the sessions that Safeguard for Privileged Sessions records (and which also have a session ID, but in a different format).

Sample request

The following command retrieves statistical data about sessions.

curl --cookie cookies https://<IP-address-of-Safeguard for Privileged Sessions>/api/audit/sessions/histogram
Request parameters

Use the following parameters to fine-tune your request for statistics:

  • ?q: Narrow down the scope of the histogram using one or more properties (elements) of the sessions.

  • ?bin-size: Determines the size of the unit for the histogram, for example, hour. Safeguard for Privileged Sessions splits the queried period to intervals of this unit, and returns the number of sessions to each interval. For example, if you query an histogram from 2018-02-12:14:40 to 2018-02-16:14:40, and you set the bin-size to day, then Safeguard for Privileged Sessions will return five datasets (one for each day). If you set the bin-size to week, then Safeguard for Privileged Sessions will return only one dataset.

  • ?start: Create a histogram from the sessions that started after the specified date. Use the ISO 8601 format for the date, for example, 2017-01-25T10:00. By default, this is the one month before the date of the request.

  • ?end: Create a histogram from the sessions that ended before the specified date. Use the ISO 8601 format for the date, for example, 2017-01-25T11:00. By default, this is the date of the request.

Response

The following snippet is a sample response received when retrieving a histogram about the audited sessions. For details of the meta object, see Introduction. Those fields of the meta object that are specific to histograms are described in table Session histogram.

Changing the display limit

You can use the ?limit option to change the number of items displayed at once. The default limit is 500.

?limit=1000

To navigate beyond the displayed set, use the offset option.

Navigating large datasets

You can use the ?offset option to navigate data sets that extend beyond the display limit. The default value of the offset is 0, this is the initially displayed set. To move to other items beyond the initial set, increase the value to a number that corresponds to the item where you want to start displaying results from.

Example: the display limit is the default 500, and the number of sessions is 1012. The initial 500 sessions are listed at:

?offset=0

To view sessions from 501 to 1000, change the offset to 501:

?offset=501

To display the remaining 12 sessions, change the offset to 1001:

?offset=1001
Sorting and filtering

Sorting and filtering alerts is currently not supported. The items are automatically sorted by the record ID. The response includes every available field.
