Variable resets

A variable reset is a configuration action that

returns a variable to its default value on the variable set new or edit variables page,
applies different reset behaviors depending on whether the variable is in a default or custom set, and
affects the value used in any intrusion policy where the variable set is linked.

Variable reset values

You can reset a variable to its default value on the variable set new or edit variables page. This table summarizes the basic principles of resetting variables.

Variable reset values
Resetting this variable type...	In this set type...	Resets it to...
default	default	the rule update value
user-defined	default	`any`
default or user-defined	custom	the current default set value (modified or unmodified)

When you reset a variable in a custom set, you return it to the current value for that variable in the default set.

If you reset or change a variable in the default set, you update the default value in all custom sets. If the reset icon is unavailable, you cannot reset the variable because it has no customized value in the set. If you have not customized the variable in a custom set, changing it in the default set also updates any intrusion policy where you have linked the variable set.

Note	Before you modify a variable in the default set, check how this change affects any intrusion policy that uses the variable in a linked custom set, especially if you have not customized the variable value in the custom set.

You can hover your pointer over the Reset icon in a variable set to see the reset value. If the customized value and the reset value match, you are in one of these situations:

you are in the custom or default set where you added the variable with the value any.
you are in the custom set where you added the variable with an explicit value and elected to use the configured value as the default value.
