For example, if all incoming traffic from external networks reaches the DMZ, you can specify that only traffic to the Traditional Anti-Virus servers is scanned. Traditional Anti-Virus scanning can be enabled in either the proactive or stream detection mode.

Maximum file size to scan: What is a DMZ? Download signature updates every x minutes: When using Scan by File Direction, you must select the direction of the data to scan, which depends on whether you want to scan files to or from the internal networks and the DMZ. You have a valid Check Point User Center user name and password. By default, any file fjletype that is not identified as non-archive is assumed to be an archive and the Traditional Anti-Virus engine tries to expand it.
IPS reliably identifies binary file types by examining the file type signatures magic numbers. Determines whether to scan or block the file. By default, all unrecognized file types are scanned. With the slider, select a protection level: Updates of virus signatures can be initiated at any time.
Archives and all other file types are recognized by their binary signature.
The following signature update methods are available the default update interval is minutes for all methods: File Type Recognition IPS has a built-in File Type recognition engine, which identifies the types of files passed as part of the connection and enables you to define a per-type policy for handling files of a given type.
See Continuous Download for further information. Indicates that updates are only downloaded by the Filstype Management Server from the default Check Point signature distribution server and then redistributed all CI gateways.
Note – Continuous Download is only relevant if you have selected to use the Activate proactive detection option. Best Practice – use this method if you want to define exactly which traffic to scan.
This mode is not available for Virtual System gateways. When nesting or compression exceeds limit or extraction fails: Update the list as necessary.
Filtype Continuous Download for more information. With the filftype, select a Zero hour malware protection level: For example, you can decide not to scan traffic passing from external networks to the DMZ, but to still scan traffic passing from the DMZ to internal networks and from the external to internal networks.
Does not allow passage of file types that are preset for blocking according to IPS advisories. For detailed explanations regarding the options described in the procedures in this section, see Understanding Traditional Anti-Virus Scanning Options. When scanning large files, if the whole file is scanned before being made available, the user may experience a long delay before the file is delivered.
Scanned data is either allowed or blocked based on the response of the state-of-the-art Traditional Anti-Virus engine. The following file types can be configured: Anti-Virus scanning is applied only to accepted traffic that was allowed by the security policy. This method usually results in faster update times.
Using Traditional Anti-Virus
Download from My local Security Management Server: Note – It is important to configure a valid DNS server address on your management and gateway in order for the signature update to work.
Allows files to pass fieltype the Security Gateway without being scanned for viruses. The limit protects the gateway resources and the destination client. IPS has a built-in File Type recognition engine, which identifies the types of files passed as part of the connection and enables you to define a per-type policy for handling files of filetye given type.
In newly installed systems, stream mode is activated by default. Note – An email is treated as an archive and as a result it is not affected when the file exceeds the limit. Using this method the default is fairly intuitive and does not require the specification of hosts cmz networks. When Traditional Anti-Virus engine fails to initialize: Updates of the virus signature can be scheduled at a predefined interval.
The Mail Traditional Anti-Virus policy prevents email from being used as a virus delivery mechanism. This mode uses sandboxes and heuristics to detect malicious code throughout the traffic as opposed to passive signature based detection.
If a virus is found during the scan, file delivery to the client is terminated.
