Sophos Anti-Virus for Linux
As containers are becoming more widely deployed on Linux Servers, the need for security is paramount to ensure any running containers have not been injected with malware.
Sophos Antivirus for Linux has been enhanced to improve detection of malware in Docker containers using on-access scanning and to improve the way in which detections in Docker containers are presented within the Sophos management consoles. Now, when a threat is identified within a Docker container, the threat report will state the path and hostname of the container. This will be displayed as (container hostname=<hostname>).
Threat detection within Docker containers has been available since the following versions of Sophos Antivirus for Linux:
- SAV for Linux version 9.13.0+
- SAV for Linux version 10.1.1+ (Sophos Central only)
For Sophos Antivirus for Linux to detect threats in Docker containers, the Talpa on-access driver must be used. The FAnotify kernel interface does not support scanning inside containers.
A recent, supported version of Docker will need to be installed and configured, preferably from the operating system vendor’s package repositories.
The Sophos Antivirus for Linux Docker scanning functionality is available on Supported releases of the following platforms:
Red Hat, Ubuntu, CentOS, SUSE

From the Docker web site, the following anti-virus consideration is recommended:
When antivirus software scans files used by Docker, these files may be locked in a way that causes Docker commands to hang.
One way to reduce these problems is to add the Docker data directory (/var/lib/docker on Linux or $Env:ProgramData on Windows Server) to the antivirus’s exclusion list. However, this comes with the trade-off that viruses or malware in Docker images, writable layers of containers, or volumes are not detected. If you do choose to exclude Docker’s data directory from background virus scanning, you may want to schedule a recurring task that stops Docker, scans the data directory, and restarts Docker.
