Virus Scan

Introduction

The Virus Scan service will scan for viruses at the filesystem level. When a file is accessed from any protocol, the Virus Scan service will first scan the file, and both deny access and quarantine the file if a virus is found. Once a file has been scanned with the latest virus definitions, it is not rescanned until it is next modified. Files accessed by NFS clients that have cached file data or been delegated read privileges by the NFSv4 server may not be immediately quarantined.

Properties

Property
Description
Maximum file size to scan
Files larger than this size will not be scanned, to avoid significant performance penalties. These large files are unlikely to be executable themselves (such as database files), and so are less likely to pose a risk to vulnerable clients. The default value is 1GB.
Allow access to files that exceed maximum file size
Enabled by default, this allows access to files larger than the maximum scan size (which are therefore unscanned prior to being returned to clients). Administrators at a site with more stringent security requirements may elect to disable this option and increase the maximum file size, so that all accessible files are known to be scanned for viruses.

Changing services properties is documented in the BUI and CLI sections of services. The CLI property names are shorter versions of those listed above.

File Extensions

This section allows control over which files are or are not scanned, based on filename pattern matching. The default value, "*", will cause all files to be scanned (impacting performance on all file access). It may suit your environment to scan only a subset of files deemed to pose the greatest risk.

For example, to scan all high-risk filename patterns, including zip files, but not files whose names match the pattern "data-archive*.zip", one might configure this setting as follows:

Action
Pattern
Scan
exe
Scan
com
Scan
bat
Scan
doc
Don't Scan
data-archive*.zip
Don't Scan
*
Scan
zip

Note that "Don't Scan *" is required to prevent scanning of all other file types not explicitly included in the scan list.

Scanning Engines

In this section, specify which scanning engines to use. A scanning engine is an external third-party virus scanning server which the appliance contacts using ICAP (Internet Content Adaptation Protocol, RFC 3507) to have files scanned.

Property
Description
Enable
Use this scan engine
Host
Hostname or IP address of the scan engine server
Maximum Connections
Maximum number of concurrent connections. Some scan engines operate better with connections limited to 8.
Port
Port for the scan engine

Logs

Log
Description
vscan
Log of the Virus Scan service

To view service logs, refer to the Logs section from Services.

Tasks

The following are example tasks. See the BUI and CLI sections for how these tasks apply to each interface method.

Virus Scan Tasks

Configuring virus scanning for a share

  1. Go to Configuration->Services->Virus Scan.
  2. Set desired properties.
  3. Apply/commit the configuration.
  4. Go to Shares.
  5. Edit a filesystem or a project.
  6. Select the "General" tab.
  7. Enable the "Virus scan" option.
