CIFS support

File filtering and antivirus scanning for proxy-based inspection on Common Internet File System (CIFS) traffic is supported.

File filtering for CIFS is performed by inspecting the first 4kB of the file to identify the file's magic number. If a match occurs, CIFS file filtering prevents the CIFS command that contains that file from running.

The CIFS security profile handles the configuration of file filtering on CIFS. The antivirus profile handles the antivirus configuration for CIFS scanning.

For a CIFS profile to be available for assignment in a policy, the policy must use proxy inspection mode. See Proxy mode inspection for details.

The following are not supported by CIFS scanning in proxy inspection mode:

  • File types and infections within archive files cannot be detected.
  • Oversized files cannot be detected.
  • Special condition archive files (encrypted, corrupted, mailbomb, etc.) marked by the antivirus engine are blocked automatically.
  • IPv6 CIFS traffic is not supported.

Configure file-type filtering and antivirus scanning on CIFS traffic

To configure file-type filtering and antivirus scanning on CIFS traffic:
  1. Configure a CIFS domain controller
  2. Configure a CIFS profile
  3. Configure an antivirus profile

Configure a CIFS domain controller

The domain controller must be configured when CIFS traffic is encrypted, like SMB 3.0 traffic. The configuration tells the FortiGate the network location of the domain controller and the superuser credentials.

To Configure the CIFS domain controller:
config cifs domain-controller
    edit "DOMAIN"
        set domain-name "EXAMPLE.COM"
        set username "admin-super"
        set password ENC 1mKKNo0z95t/+9B9IisyLsSfevTNRePp6mFk+dtDdZ7r2V8CYUrXp7kcxVauWpdHYlQsrY8g2Ypo+UYDsBUxELDpfLYC7C31rCm6WD0jYiRcQ/kZhWpwB5Dl3W7Z9865r/ntVu1YCsWex/+MnnMYyzFXaNJriXuPLYKEv2fe79NpmSuvouEMvc6zgPPBbXE+28SHzA==
        set ip 172.16.201.40
    next
end

Configure a CIFS profile

To create a CIFS profile, configure the server credential type and add file filter entries.

Set the CIFS server credential type

The CIFS server credential type can be none, credential-replication, or credential-keytab.

none

The CIFS profile assumes the CIFS traffic is unencrypted (used with SMB 2.0). This is the default value.

config cifs profile
    edit "cifs"
        set server-credential-type none
    next
end
credential-replication

To decrypt CIFS traffic, FortiOS obtains the session key from the domain controller by logging in to the superuser account. The domain controller must be configured.

config cifs profile
    edit "cifs"
        set server-credential-type credential-replication
        set domain-controller "DOMAIN"
    next
end

Variable

Description

domain-controller <string>

The previously configured domain to decrypt CIFS traffic for.

credential-keytab

To decrypt CIFS traffic, FortiOS uses a series of keytab values. This method is used when the SMB connection is authenticated by Kerberos. Keytab entries must be configured, and are stored in FortiOS in plaintext.

config cifs profile
    edit "cifs"
        set server-credential-type credential-keytab
        config server-keytab
            edit "keytab1"
                set keytab "BQIAAABFAAEAC0VYQU1QTEUuQ09NAAdleGFtcGxlAAAAAVUmAlwBABIAILdV5P6NXT8RrTvapcMJQxDYCjRQiD0BzxhwS9h0VgyM"
            next
        end
    next
end

Variable

Description

keytab <keytab>

Base64 encoded keytab file containing the credentials of the server.

Configure CIFS profile file filtering

Multiple file filter entries can be added to a profile.

To configure file filter entried in a CIFS profile:
config cifs profile
    edit "cifs"
        config file-filter 
            set status {enable | disable}
            set log {enable | disable}
            config entries 
                edit <filter>
                    set comment <string>
                    set action {log | block}
                    set direction {incoming | outgoing | any}
                    set file-type <file_type>
                next
            end
        end
    next
end

Variable

Description

status {enable | disable}

Enable/disable file filter (default = enable).

log {enable | disable}

Enable/disable file filter logging (default = enable).

comment <string>

A brief comment describing the entry.

action {log | block}

The action to take for matched files:

  • log: Allow the content and write a log message (default).
  • block: Block the content and write a log message.

direction {incoming | outgoing | any}

Match files transmitted in the session's originating (incoming) and/or reply (outgoing) direction (default = any).

file-type <file_type>

The file types to be matched (default = none). See Supported file types for details.

Configure an antivirus profile

The antivirus profile handles the antivirus configuration for CIFS scanning.

To configure an antivirus profile:
config antivirus profile
    edit "av"
        ...
        config cifs
            set options {scan avmonitor quarantine}
            set archive-block {encrypted corrupted partiallycorrupted multipart nested mailbomb fileslimit timeout unhandled}
            set archive-log {encrypted corrupted partiallycorrupted multipart nested mailbomb fileslimit timeout unhandled}
            set emulator {enable | disable}
            set outbreak-prevention {disabled | files | full-archive}
        end
    next
end

Variable

Description

options {scan avmonitor quarantine}

Enable/disable CIFS antivirus scanning, monitoring, and quarantine.
