Recent concerns over the security offered by containers are not unjustified, the chief technologist for Germany-based SUSE in the Asia-Pacific says, adding however that there are a lot of operational things that could be done to mitigate the risk.

The increasing use of containers has opened a new avenue of entry for malicious attackers, a researcher from security outfit CyberArk Labs has warned, pointing out that container security was not straightforward and not well understood.

The credentials of some 190,000 account holders at Docker Hub, the official repository for Docker container images, have been exposed due to "a brief moment of unauthorised access", the site says.
