Internet Content Adaptation ProtocolДЇor example, if a virus is detected in a file but the ICAP server is unable to repair it, that file can be re-sent to the ICAP server after the virus database had been updated, and the ICAP server might be able to repair the file.Web services are widely deployed by enterprises to support mission critical business applications.ДЇurther, SOAP messages can carry additional payload through attachmentsand hence attachments should be scanned for viruses before they are permitted to enter the secure zone of any corporate enterprise. Antivirus allows specific file s to be manually sent to an ICAP server for scanning at any time. Note that antivirus policies do not target snapshots, and only on-access scans include snapshots. Exclusion rules can also be configured to prevent a policy from sending certain files within the specified root directory, based on the size, name, or extension of the file.ДЄntivirus scans are managed by the OneFS Job Engine and function similarly to and contend with other system jobs. OneFS Antivirus policies target a specific directory tree on the cluster and can either be run manually at any time or scheduled for automatic execution. Antivirus scanning policies can be crafted that send files from a specified directory to be scanned. In this case, it can be skipped, as it would not need to be re-scanned if the ICAP server database has not been updated since its previous scan. Scanning files as they are both opened and closed will not necessarily increase security, but it will usually improve data availability, because that file may have already been scanned since it was last modified. OneFS can also be configured to deny access to files that cannot be scanned by an ICAP server, which can further increase the delay. Scanning files before they are opened is more secure, however it does add access latency. The user cannot access that file until the scan is complete.

If a cluster is configured to scan files before they are opened, when a user attempts to download a file, OneFS first sends the file to an ICAP server to be checked. Similarly, if an ICAP server is unable to scan a file, that file will still be accessible to users.

If a virus was introduced to the file from the first user, the second user would be able to access the infected file. However, it is possible that after a user modifies or creates a file, a second user might access the file before the file is scanned. In this configuration, users can always access files without any delay. It then sends the file to an ICAP server to be scanned when convenient. If antivirus is configured for scanning files after they are closed, when a user creates or modifies a file on the cluster, OneFS queues the file to be scanned. Sending files to be scanned after they are closed is faster but less secure, whereas scanning before they are opened is slower but safer. OneFS can be configured to send files to be scanned prior to opening, after they are closed, or both.

OneFS works with antivirus software that conforms to the ICAP standard, and the following list includes the supported and most widely used antivirus vendors. Note that Antivirus scanning is available only if all nodes in the cluster are connected to the external network NANON configurations are not supported. If a file has already been scanned and has not been modified, OneFS will not send the file to be scanned unless the virus database on the ICAP server has been updated since the last scan. OneFS can also be configured to either request that ICAP servers attempt to repair infected files, or to protect users against potentially dangerous files by truncating or quarantining infected files.Д«efore OneFS sends a file to be scanned, it ensures that the scan is not redundant.

If a threat is detected, OneFS typically alerts cluster admins by firing an event, displaying near real-time summary information, and documenting the threat in an antivirus scan report. To do this, OneFS sends files to an ICAP server running third-party antivirus scanning software, which scrutinizes the files for viruses and other threat signatures. So, it seemed like a useful topic to review in a couple of blog articles. It appears that security is top of mind currently, with several customer discussions of late around OneFS and antivirus practices.
