Contain from Active List

Have you ever wanted to create a rule that has the ‘Contain From Active List’ condition in ArcSight?

Before starting – consider the following:

  • Be aware of the Resources’ costs
  • Plan how to adapt the variables to your needs.


Use case Example:

We want to check if at least one of file types in the Active List is found in a string that contains many file types.

Part A – Define the Active List content:

Step 1 – Create an Active List with 2 columns:

  1. Flag (as a key field) – Should be the same value for all the strings that need to be checked.
  2. StringToCheck

Note: Check the Allow multi-mapping checkbox.

Step 2 – Add to the Active List the file types you want to find (Flag value has to be the same):

Step 3 – Define the rule’s variables:

Define the variables as follows:

a) Flag

b) AL

c) ALList2String

d) StripApostrophe


e) ReplaceComma


f) ReplaceFound


g) YESorNO

View the results after each variable’s processing:

Wow! You made it!
