Cloud SWG Rest API
IBM Security QRadar SIEM
Corrupted zip files, generated by Cloud Secure Web Gateway (SWG) API can result in events from any affected Log Sources not being ingested and therefore parsed by QRadar.
A corrupted zip can occurred due to an internal problem with the Cloud SWG Rest API, however, the client (QRadar) needs to have the ability to recover from such events.
If the client cannot recover from these types of events automatically, the data feed needs to be restarted manually.
To restart the data feed, collect the logs from /var/log/qradar.log and open a case with IBM Security support.
