JSON SNS configuration

For instructions on how to enable the forwarding of events to Amazon SNS topics, see Access events with Amazon SNS. If you opt to directly edit the JSON SNS configuration, this page provides details on how to do it.

The configuration language used to define which events are sent to which topics is modeled after Amazon's Policy language for SNS, described in the Amazon documentation.

The configuration is a special JSON-encoded document that says which conditions an event must meet in order to be published to a topic. A basic configuration looks like:

{
  "Version": "2014-09-24",
  "Statement": [statement1, statement2, ...]
}
      

Version

The Version element specifies the version of the configuration language. The only currently valid value is the string "2014-09-24"

"Version": "2014-09-24",
      

Statement

The Statement element is an array of individual statements. Each individual statement is a distinct JSON object giving the SNS topic to send to if an event meets given conditions.

"Statement": [{...}, {...}, ...]
      

An individual statement has the form

{
  "Topic": "destination topic",
  "Condition": {conditions event must meet to be published to the destination topic}
}
      

Topic

The Topic element must be the Amazon Resource Name of the SNS Topic to publish to.

"Topic": "arn:aws:sns:us-east-1:012345678901:myTopic"
      

Condition

The Condition element is the most complex part of the configuration. It contains one or more conditions an event must match in order to be published to the topic. Each condition may itself contain multiple key-value pairs, and some conditions support multiple values for each key. The keys in conditions are the names of properties from events.

"Condition": {
  "ConditionName": {
    "key1": [value1, value2],
    "key2": value3
  },
  "ConditionName2": {
    "key3": [value4]
  },
  ...
}
      

Possible condition names and their syntax are described below.

Bool

The Bool condition performs Boolean matching. To match, an event must have a property with the desired Boolean value. If the property in the event exists but is not itself a Boolean value, the property is tested as follows:

  • Numbers equal to 0 evaluate to false. Numbers not equal to 0 evaluate to true.
  • Empty strings and the special strings "false" and "0" evaluate to false. Other strings evaluate to true.
  • Any other property value in an event cannot be converted to a Boolean and will not match.

Allows for multiple values? No

The following example shows a configuration that publishes events that have a "DetectOnly" property with a value false:

{   
  "Version": "2014-09-24",
  "Statement": [
    {
      "Topic": "arn:aws:sns:us-east-1:012345678901:myTopic",
      "Condition": {
        "Bool": {
          "DetectOnly": false
        }
      }
    }
  ]
}
      

Exists

The Exists condition tests for the existence or non-existence of a property in an event. The value of the property is not considered.

Allows for multiple values? No

The following example shows a configuration that publishes events when the event has the property "Severity" but does not have the property "Title":

{    
  "Version": "2014-09-24",
  "Statement": [
    {
      "Topic": "arn:aws:sns:us-east-1:012345678901:myTopic",
      "Condition": {
        "Exists": {
          "Severity": true,
          "Title": false
        }
      }
    }
  ]
}
      

IpAddress

The IpAddress condition tests the value of an event's property is an IP address in a range given in CIDR format, or exactly equals a single IP address.

Allows for multiple values? Yes

The following example shows a configuration that publishes events when the event has the property "DestinationIP" with an IP address in the range 64.23.0.0/16, or to 216.104.20.189:

{   
  "Version": "2014-09-24",
  "Statement": [
    {
      "Topic": "arn:aws:sns:us-east-1:012345678901:myTopic",
      "Condition": {
        "IpAddress": {
          "DestinationIP": ["64.23.0.0/16", "216.104.20.189"]
        }
      }
    }
  ]
}
      

NotIpAddress

The NotIpAddress condition tests the value of an event's property is not an IP address in any of the specified IP address ranges.

Allows for multiple values? Yes

The following example shows a configuration that publishes events when the event has the property "DestinationIP" with an IP address not in the range 10.0.0.0/8:

{   
  "Version": "2014-09-24",
  "Statement": [
    {
      "Topic": "arn:aws:sns:us-east-1:012345678901:myTopic",
      "Condition": {
        "NotIpAddress": {
          "DestinationIP": "10.0.0.0/8"
        }
      }
    }
  ]
}
      

NumericEquals

The NumericEquals condition tests the numeric value of an event's property equals one or more desired values. If the property in the event exists but is not itself a numeric value, the property is tested as follows:

  • Strings are converted to numbers. Strings that cannot be converted to numbers will not match.
  • Any other property value in an event cannot be converted to a number and will not match.

Allows for multiple values? Yes

The following example shows a configuration that publishes events when the event has the property "Protocol" with the value 6 or 17:

{    
  "Version": "2014-09-24",
  "Statement": [
    {
      "Topic": "arn:aws:sns:us-east-1:012345678901:myTopic",
      "Condition": {
        "NumericEquals": {
          "Protocol": [6, 17]
        }
      }
    }
  ]

          "Risk" : [2, 3]
        }
      }
    }
  ]
}
      

NumericGreaterThan

The NumericGreaterThan condition tests the numeric value of an event's property is strictly greater than a desired value. If the property in the event exists but is not itself a numeric value it is converted to a number as described for NumericEquals.

        }
      }
    }
  ]
}

Event Description

When published to Amazon SNS, events are sent as simple JSON objects encoded as strings. The properties in the objects are the elements of the event, and the values of the properties are typically strings or numbers. This section describes the properties that events can have and what values these properties can take.

Event Data Types

Properties in an event will be one of the data types described in the following table:

Data Type Description
Boolean The value will be the JSON true or false value.
Integer The value will be a JSON int value. Deep Security does not output floating point numbers in events. Note that integer types in events are not guaranteed to fit in 32 bit integers.
Integer (enum) The value will be a JSON int value, with the additional restriction that it can only be one of a limited set of enumerated values.
String The value will be a JSON string value.
String (Date) The value will be a date and time encoded in a JSON string value. Dates are encoded using ISO 8601 format YYYY-MM-DDThh:mm:ss.sssZ, always using 'Z' for the time zone designator and including three digits for sub-seconds. See the W3C note on date and time formats for more details about this encoding.
String (IP) The value will be an IPv4 or IPv6 address encoded in a JSON string value.
String (MAC) The value will be a JSON string value, with the additional restriction that it will contain a network MAC address.
String (URL) The value will be a JSON string value, with the additional restriction that it will contain a URL.
String (enum) The value will be a JSON string value, with the additional restriction that it can only be one of a limited set of enumerated values.

Event Properties

This section describes all the properties that may be seen in an event. Note that events will not necessarily contain all of the properties that are listed as applicable for the event type; in some circumstances a property will not apply and will not be present in the JSON object.

Example Configurations

This section gives some SNS configuration examples for different scenarios.

Send all critical intrusion prevention events to an SNS topic

{   
  "Version": "2014-09-24",
  "Statement": [
    {
      "Topic": "arn:aws:sns:us-east-1:012345678901:myTopic",
      "Condition": {
        "NumericEquals": {
          "Severity": 4
        },
        "StringEquals" : {
          "EventType" : "PayloadLog"
        }
      }
    }
  ]
}
      

Send different events to different SNS topics

This example shows sending all system events to one topic and all integrity monitoring events to a different topic.

{   
  "Version": "2014-09-24",
  "Statement": [
    {
      "Topic": "arn:aws:sns:us-east-1:012345678901:systemEventsTopic",
      "Condition": {
        "StringEquals" : {
          "EventType" : "SystemEvent"
        }
      }
    },
    {
      "Topic": "arn:aws:sns:us-east-1:012345678901:integrityTopic",
      "Condition": {
        "StringEquals" : {
          "EventType" : "IntegrityEvent"
        }
      }
    }
  ]
}

Multiple statements vs. multiple conditions

If you create multiple statements for the same SNS topic, those statements are evaluated as if they are joined by "or". If a statement contains multiple conditions, those conditions are evaluated as if they are joined by "and".

Multiple statements

This is an example of what not to do. The first statement says to forward all events other than "System Settings Saved". The second statement says to forward all "System Settings Saved" events. The result is that all events will be forwarded because any event will match either the condition in the first statement or the one in the second statement:

{   
  "Version": "2014-09-24",
  "Statement": [
    {
      "Topic": "arn:aws:sns:us-east-1:012345678901:myTopic",
      "Condition": {
        "StringNotLike" : {
          "Title" : "System Settings Saved"
        }
      }
    },
    {
      "Topic": "arn:aws:sns:us-east-1:012345678901:myTopic",
      "Condition": {
        "StringLike" : {
          "Title" : "System Settings Saved"
        }
      }
    }
  ]
}

Multiple conditions

This is another example of what not to do. The first condition says to forward all events other than "System Settings Saved". The second condition says to forward all "System Settings Saved" events. The result is that no events will be forwarded because no events will match both the condition in the first statement and the one in the second statement:

{   
  "Version": "2014-09-24",
  "Statement": [
    {
      "Topic": "arn:aws:sns:us-east-1:012345678901:myTopic",
      "Condition": {
        "StringNotLike" : {
          "Title" : "System Settings Saved"
    	 },
        "StringLike" : {
          "Title" : "System Settings Saved"
        }
      }
    }
  ]
}
