When uploading the files to some websites, Data Loss Prevention (DLP) is unable to log or detect it.
Data Loss Prevention 6.2.1325 or later builds adds two (2) configuration keys to allow customers to manually set the monitored websites. Meanwhile, DLP 6.2.1385 or later builds user can try to monitor all websites by using “*” in configuration.
These two keys are:
[Monitoring all Websites]: (DLP 6.2.1385 or later builds)
For example, upload files to site1.com and post content to site2.com is not being blocked by DLP while setting HTTP/HTTPs in monitor channel of policy. You may use the configuration “PARSER_MONITOR_LIST “and “MONITOR_FILE_UPLOAD_WEBSITES “ to add these two websites into DLP monitor list.
