Standard Fields

Panther's log processing applies normalization fields (IPs, domains, etc) to all log records. These fields provide standard names for attributes across all data sources enabling fast and easy data correlation.
For example, each data source has a time that an event occurred, but each data source will likely not name the attribute the same, nor is it guaranteed that the associated time has a timezone consistent with other data sources.
The Panther attribute p_event_time is mapped to each data source's corresponding event time and normalized to UTC. This way you can query over multiple data sources joining and ordering by p_event_time to properly align and correlate the data despite the disparate schemas of each data source.
All appended standard fields begin with p_
Required Fields
The fields below are appended to all log records:
Field Name
Type
Description
p_log_type
string
The type of log.
p_row_id
string
Unique id (UUID) for the row.
p_event_time
timestamp
The associated event time for the log type is copied here and normalized to UTC.
p_parse_time
timestamp
The current time when the event was parsed normalized to UTC.
If an event does not have a timestamp, then p_event_time will be set to p_parse_time, which is the time the event was parsed.
The "any" Fields
A common security question is often of the form of: “was some-indicator ever observed in our logs?”
Notice that the relationship of the indicator is not a concern initially, simply the presence or absence of activity is of interest.
To allow this question to be answered over all data sources the "any" fields below are appended to rows of data as appropriate.
The all_logs view is provided over all data sources to make queries easy for users to find activity for an indicator in a single query.
Field Name
Type
Description
p_alert_id
string
Id of alert related to row.
p_alert_creation_time
timestamp
Time of alert creation related to row.
p_alert_update_time
timestamp
Time of last alert update related to row.
p_any_aws_account_ids
array[string]
List of aws account ids related to row.
p_any_aws_arns
array[string]
List of aws arns related to row.
p_any_aws_instance_ids
array[string]
List of aws instance ids related to row.
p_any_aws_tags
array[string]
List of aws tags related to row as "key:value" pairs.
p_any_domain_names
array[string]
List of domain names related to row.
p_any_ip_addresses
array[string]
List of ip addresses (v4 or v6 in string form) related to row.
p_any_md5_hashes
array[string]
List of MD5 hashes related to row.
p_any_sha1_hashes
array[string]
List of SHA1 hashes related to row.
p_any_sha256_hashes
array[string]
List of SHA256 hashes related to row.
p_rule_reports
map[string]array[string]
List of user defined rule reporting tags related to row.
p_rule_tags
array[string]
List of user defined rule tags related to row.
The "all_logs" View
Panther manages a view over all data sources with standard fields.
This allows you to ask questions such as "was there any activity from some-bad-ip and if so where?".
The query below will show how many records (by log type) are associated with IP address 95.123.145.92:
SELECT
 p_log_type, count(1) AS row_count
FROM panther_views.all_logs
WHERE year=2020 AND month=1 AND day=31 AND contains(p_any_ip_addresses, '95.123.145.92')
GROUP BY p_log_type
From these results, you can pivot to the specific logs where activity is indicated.
Standard Fields in Rules
The Panther standard fields can be used in rules. For example, this rule triggers when any GuardDuty alert is on a resource tagged as 'critical':
