Masking Sensitive Data in Chat Server and UCS

Logs and chat transcripts may contain sensitive data such as credit card numbers, phone numbers, Social Security numbers, and so on. You can omit this data from logs and mask it in transcripts by properly configuring Chat Server and UCS.

UCS

Some configuration of UCS is required for all channels. The following table summarizes what is needed for each channel.

Channel	Section	Option	Value
All	log	log4j.logger.ucs.svc.indexing	warn
All	settings (of UCS DAP)	interpret-prepared-statements	false
Chat	log-filter-data	StructuredText	hide
Chat	log-filter-data	Transcript	hide

Chat Channel

Logs

• In the [settings] section, set message-log-print-size to 0. This means that logs do not show the messages sent between chat participants. Where a message occurs, the log shows [truncated from size=x], where x is the number of characters in the suppressed message.
• In the [log-filter-data] section,
  • Set StructuredText to hide so that logs will omit the transcript that UCS sends to Chat Server.
  • Set Transcript to hide so that logs will omit the transcript that Chat Server sends to UCS.
