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. This mode uses sandboxes and heuristics to detect malicious code throughout the traffic as opposed to passive signature based detection.
In newly installed systems, stream mode is activated by default. Scan by File Smz enables you to set file scanning according to the file’s fiiletype not necessarily the connection’s origin and destination. Selecting Data to Scan 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 dmmz internal networks and the DMZ. Does not allow passage of file types that are preset for blocking according to IPS advisories.
To enable and configure Traditional Anti-Virus protection: A similar problem may arise when using client applications with short timeout periods for example, certain FTP clients to download large files. You have a valid Check Point User Center user name and password. This method usually results in faster update times. Download updates from a Check Point server prior to downloading signature updates. Other formats can be considered safe because they are relatively hard to tamper with.
Scanning by File Direction: The following signature update methods are available the default update interval is minutes for fletype methods: See Continuous Download for further information. This mode is based flletype state-of-the-art virus signatures that are frequently updated in order to detect recent Malware outbreaks.
Stream mode – the kernel processes the traffic for the selected protocols on the stream of data without storing the entire file. 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. Indicates that updates are only downloaded by the Security Management Server from the default Check Point signature distribution server and then redistributed all Filettpe gateways.
Enables you to define the update interval. Updates of virus signatures can be initiated at any time. For detailed explanations regarding the options described in the procedures in this section, see Understanding Traditional Anti-Virus Scanning Options. IPS reliably identifies binary file types by examining the file type signatures magic numbers.
Some file types for example, Adobe Acrobat PDF and Microsoft Power Point files can open on a client computer before the whole file has been downloaded. The limit protects the gateway resources and the destination client. Use the instructions in this section to configure Traditional Anti-Virus in your system.
With the slider, 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.

Understanding Proactive and Stream Mode Detection Traditional Anti-Virus scanning can be enabled in either the proactive or stream detection mode. By default, any file type that is not identified as non-archive is assumed to be an archive and the Traditional Anti-Virus engine tries to expand it. Note – It is important to configure a valid DNS server address on your management and gateway in order for the signature update to work.
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. Archive File Handling These file handling archiving options are available: If you want most or all files in a given direction to be scanned, select Scan by File Direction.
Determines whether to scan or block the file.
Internal Access to DMZ
Maximum archive nesting level: What is considered to be safe changes according to published threats and depends on how the administrator balances security versus performance considerations.
Scan Failure These scan failure options are available: GIFwhich can be spoofed. This mode is not available for Virtual System gateways.
This limit protects the gateway and destination client from attacks that employ deep nesting levels. Best Practice – use this method if you want to define exactly which traffic to scan. Clear the checkbox to enable stream filetyle detection.
Limits the file size that is allowed to pass through the gateway. You can specify the file types for which xmz do not want Continuous Download to occur. By proactively scanning the Internet, the Data Center identifies massive virus outbreaks as soon as they occur.
If Proactive Detection was configured, select Activate Continuous Download to prevent client time-outs when large files are scanned. File Handling The following file handling options are available: The security server forwards the data stream to the Traditional Anti-Virus engine.
Updates of the virus dma can be scheduled at a predefined interval. The following signature update methods are available the default update interval is minutes for all methods:. Stream detection mode – where traffic is scanned for viruses as giletype passes through the network on streams of data, without storing entire files and without causing an impact on performance. Configuring Traditional Anti-Virus For detailed explanations regarding the options described in the procedures in filefype section, see Understanding Traditional Anti-Virus Scanning Options.
Before performing Traditional Anti-Virus scanning, the gateway reassembles the entire file and then scans it.
Scanned data is either allowed or blocked based on the response of the state-of-the-art Traditional Anti-Virus engine.
