MALWARE AND CONTENT SCANNING

Regex

the course is saying that its recommended to use "Malware and content scanning" instead of "Filtering common web ports" So ive done some testing to check if malware will be blocked if i'll set only "malware and content scanning" unfortunately, files sended with no  problem. Ive attached screens from policy of FW rule and ssl/tls rule. Also ive added via Console non-standard port for https and ftp <- but ftp is a different story. 

 

 

BUT if im setting options below(screenshot) it does working. Tested malware are blocked and i can see it in the LOGS.

    Well, i dont really understand what are you asking for. If im undertstanding you correctly then - My service is working on non-standard HTTPS port(8443) Im not using unencrypted traffic to my server. How i did my testing ? From my PHONE(WAN - PublicIP_LTE) ive lunched an up (QFILE) and uploading a tested malware file, THATS ALL ;) all the rest as metnioned above ^^

    The Proxy is only used for Internal to external communication.

    You cannot rely on the Proxy for external to internal communication.

    For such services, you need a reverse proxy (WAF).

    So you need to configure the WAF.

    Really a WAF ? 8443 is used for various services in this case im using for a file transfer. Im using DDNS service example: "somename.ddns.myqnapcloud.com" or "somename.ddns.net" all is on port 8443. this port is also used for managment,  server is a QNAP DEVICE. ;) If should using WAF can you point for some "hot to" ? ;)

    Roman, Luca is correct. Traffic from lan to wan is filtered by proxy. From wan to lan by reverse proxy. This is not a Sophos limitation but how the protocol works.

    You can filter and apply Ips filter from lan to wan and viceversa but ips can stop only certain malware.

    Really. So you are tring to say im not able to bloc or scan a traffic from WAN to LAN on a specific port ?? I dont wanna to advertised other solution but on FORTIGATE devices it works excelent so "limitations is not cuzed by a protocol" beside that. So why malware is blocked when im not using DPI but only Webproxy and im uploading  a file from WAN. ? Cant it be done by WAF ? Sophos XG which im using is for HOME USAGE. So im ok if ssl traffic from will inspected via cert from sophos appliance_CA

    If it is SFTP, you will need to decrypt the traffic first with XG in order to scan it.

    Also if you want FTP traffic to be scanned by XG, you will need to run the FTP server over the default port (21). XG is only port agnostic for HTTP traffic, if you run FTP over a non-standard port, It will not detect it as FTP, hence it will not scan it.

     

    Thanks!

    No one is able to scan encrypted traffic, if your running FTPS you will need to decrypt it first with SSL/TLS Inspection rules.

     

    Just tested myself with FTPS, XG with the new TLS engine has able to decrypt it and scan over it's default port (990).

    NO, I has wrong, XG doesn't scan decrypted FTPS, on v18 your able to decrypt it but not scan it, incredible.
