Regex policy class

The Regex policy class let you implement text data validation based on static templates (regular expressions).

A PSL description of the Regex class is provided in the following file:

/opt/KasperskyOS-Community-Edition-<version>/toolchain/include/nk/regex.psl

Regex class object

A Regex class object is automatically created when connecting the PSL description of the class.

You may need to create additional objects of the Regex class to declare audit profiles associated with these objects.

Regex class objects do not have configurations.

Regex class policies

The Regex policy class consists of the following expression policies:

• match {text: Text, pattern: Pattern}

  Takes the Text string and Pattern regular expression. Returns a Boolean type value: True if match, otherwise False.

  Example: assert (re.match {text: message.text, pattern: "^[0-9]*$"})

• select {text: Text}

  Accepts a string. Intended for use with the choice operator to check for matches with multiple regular expressions.

  Example:

  choice (re.select {text: "hello world"}) {

  "^hello .*": grant ()

  ".*world$" : grant ()

  _ : deny ()

  }
