Qualys SwCA Scanner for Linux 1.3.1

April 06, 2026

With this release of SwCA Scanner for Linux, we are introducing the following new features and enhancements.

Optimized Logging for Linux SwCA Scanners

We optimized the logging process for Linux SwCA Scanners to ensure efficient operation and accessibility.

Easy Access for SwCA Logs

The SwCA Scanner for Linux generates a separate log file for easy access, enabling more efficient analysis and troubleshooting. Previously, SwCA logs were captured in the Cloud Agent scan log file.

The SwCA logs are now available at: /var/log/qualys/qualys-swca.log

Optimal Default Log Level

We updated the default log-level for SwCA processes to Warning. This reduces the log file size by omitting regular process logs, optimizing the usage of asset resources.

SwCA supports the following log levels: Trace, Debug, Information, Warning, and Error.

You can change the log level in the SwCA configuration file (/usr/local/qualys/cloud-agent/swca/config/qagent-swca.yaml) by configuring the log_level parameter to trace, debug, info, warn, or error. 

 The SwCA log level is independent of the Cloud Agent log level.

Behavior Change

There is no behavior change for this release. 

Platform Coverage Support

No new platform coverage is added in this release.

Issues Addressed

We fixed the following important and notable issues.

Component/Category	Description
SwCA Scans	We fixed an issue where temporary files created in /tmp during SwCA scans were not getting deleted. Now, SwCA cleans temporary files after scan completion.
SwCA Memory Usage	We fixed an issue where the SwCA scan was causing high memory consumption. We have enhanced SwCA for optimal memory usage during the scan.
Third-party Library Update	The SwCA third-party libraries were outdated. We have updated these third-party libraries.
