URI checking is a way of analyzing URI content in HTTP traffic against Which is similar to antispam realtime null route list (RBL) lookups. Sophos Uniform Resource Identifier checking-Sophos provides Uniform Resource Identifier (URI) checking, You can set the following actions: block, log-and-permit, and permit.įail mode handling of supported options with Sophos is much the same The following fail mode options are supported: content-size,ĭefault, engine-not-ready, out-of-resource, timeout, and too-many-requests. When a virus is found and the data content is dropped. Sophos antivirus scan result handling-With Sophos antivirus, the TCP, traffic is closed gracefully SSL forward proxy and Sophos antivirus bypass the traffic. If HTTPS traffic hits the allowlist of SSL forward proxy, Handle the new connection and Sophos antivirus bypasses the traffic. If the system resource is low, SSL forward proxy cannot Is incomplete because of compatibility issues, connection drops. If the SSL proxy handshake with the client and server If SSL proxy does not parse the first handshake packetįrom the client, SSL forward proxy bypasses the traffic. UTM bypasses the HTTPS traffic under the following conditions: IfĬlient authentication is required by the server, UTM bypasses the SSL forward proxy does not support client authentication. The Sophos antivirus scanner determines whether UTM extracts the URL and the file checksum information fromĬleartext traffic. SSL forward proxy actsĪs the terminal for both channels and forwards the cleartext traffic The SRX Series device and the HTTPS server. The client and the SRX Series device and another SSL channel between The securityĬhannel from the SRX Series device is divided as one SSL channel between HTTPS traffic passing through the SRX Series device. Sophos antivirus over SSL forward proxy does so by intercepting Over SSL forward proxy supports HTTPS traffic. Junos OS Release 12.3X48-D25 and Junos OS Release 17.3R1, Sophos antivirus Sophos antivirus supports HTTPS traffic-Starting with MIME decoding support includes the following for each supportedīase64 decoding, printed quote decoding, and encoded word Sophos antivirus expanded MIME decoding support-Sophos antivirus offers decoding support for HTTP, POP3, SMTP,Īnd IMAP. Sophos antivirus has the following main features: For the HTTPS connection, you mustĬreate an SSL initiation profile and add the profile to the default configuration of the The new version of Sophos antivirus uses an HTTPSĬonnection for the device-to-server communication. Starting in Junos OS Release 23.1R1, content security supports the new antivirus Sophos Implicit mode-Connect to SSL/TLS encrypted port using secure channel.Įxplicit mode-First connect to unsecured channel, then secure the communication by Starting from Junos OS Release 19.4R1, the antivirus feature supports implicit andĮxplicit SMTPS, IMAPS, and POP3S protocol, and supports only explicit passive mode Starting with Junos OS Release 12.3X48-D35 and Junos OS Release 17.3R1, the UTM SophosĪntivirus (SAV) single session throughput is increased for optimizing tcp-proxy Starting with Junos OS Release 15.1X49-D100, IPv6 pass-through traffic for HTTP, HTTPS,įTP, SMTP, POP3, IMAP protocols is supported for Sophos antivirus, Web filtering andĬontent filtering security features of UTM. Manner however, it has a smaller memory footprint and is compatible with lower end Sophos supports the same protocols as full antivirus and functions in much the same Offered as a less CPU-intensive alternative to the full file-based antivirus feature. For previous releases, sophos antivirus scanning is The full file-based antivirus feature is not supported from Junos OS Release 15.1X49-D10Īnd Junos OS Release 17.3R1 onwards. The following application layer protocols are supported: HTTP, FTP, The followingĬhecks are performed for HTTP traffic: URI lookup, true file type detection, and fileĬhecksum lookup. Prevent malicious content from reaching the endpoint client or server. (UTM) is HTTP based, Uniform Resource Identifier (URI) checking is used to effectively Internal cache to maintain query responses from the external list server to improveīecause a significant amount of traffic processed by Juniper Unified Threat Management Release 23.1R1, the Sophos antivirus scanner also used a local Servers, thus there is no need to download and maintain large pattern databases on the The virus pattern and malwareĭatabase is located on external servers maintained by Sophos (Sophos Extensible List) Sophos antivirus is as an in-the-cloud antivirus solution.
