Abstract

Cortex XSOAR indicators have an active or expired status which can be set to expire after a period of time or never to expire. Set default expiration method.

Indicators can have the Expiration Status field set to Active or Expired, which is determined by the Expiration field. When indicators expire, they still exist in Cortex XSOAR, meaning they are still displayed and you can still search for them. A job that runs every hour checks for newly expired indicators and updates the Expiration Status field.

When indicators expire, the expirationStatus and expiration fields are updated. You can use Indicator Field Trigger Scripts to take actions based on indicator expiration.

You can set the default expiration method for indicators either to never expire, or to expire after a specific period of time. The default expiration method is set by the indicator type. For more information see Indicator Type Profile.

This is the hierarchy by which indicators are expired.

Method

Description

Manual

A user manually expires the indicator or sets it to never expire. This method overrides all other methods.

Script

Use the expireIndicators command to change the expiration status to Expired for one or more indicators. This script accepts a comma-separated list of indicator values, and supports multiple indicator types. For example, you can set the expiration status for an IP address, domain, and file hash: !expireIndicators value=1.1.1.1,safeurl.com,45356A9DB614ED7161A3B9192E2F318D0AB5AD10

(Same in the indicator expiration hierarchy as manual.)

Use the !setIndicators command to reset the indicators expiration value. The value can also be set to Never, so that the indicators never expire. For example, !setIndicators indicatorsValues=watson.com expiration=Never

Feed integration

Some integrations support setting the expiration method on an integration instance level, which overrides the method defined for the indicator type.

Indicator type

The expiration method (interval or never) defined according to indicator type, which applies to all indicators of this type. This is the default expiration method for an indicator.
