Unauthorized or unapproved network services lack organizational verification or validation and therefore may be unreliable or serve as malicious rogues for valid services. Automated mechanisms can be used to send automatic alerts or notifications. Such automatic alerts or notifications can be conveyed in a variety of ways (e.g., telephonically, via electronic mail, via text message, or via websites). The Palo Alto Networks security platform must either send the alert to an SNMP or Syslog console that is actively monitored by authorized personnel (including the ISSO and ISSM) or use e-mail to send the alert directly to designated personnel.
