Log FTP upload traffic with a specific pattern

This configuration will log FTP upload traffic with the following patterns:

• keyword = demo

• regex = demo(regex){1,5}

• hex = e6b58be8af95

The dictionary entries have repeat match enabled. The DLP sensor is set so this is repeated five times.

To log FTP upload traffic that has specific keyword, regex, and hex patterns repeated for five times in the GUI:

1. Configure the DLP dictionary with three entries:

   1. Go to Security Profiles > Data Loss Prevention, select the Dictionaries tab, and click Create New.

   2. Enter a name (dic-case2).

   3. In the Dictionary Entries section, click Create New.

   4. Set the Type to keyword and the Pattern to demo.

   5. Enable Repeats and click OK.

      

   6. Repeat these steps to add dictionary entries for the following (with Repeats enabled):

      1. Set the Type to regex and the Pattern to demo(regex){1,5}.

      2. Set the Type to hex and the Pattern to e6b58be8af95.

         

   7. Click OK to save the dictionary.

2. Configure the DLP sensor:

   1. Go to Security Profiles > Data Loss Prevention, select the Sensors tab, and click Create New.

   2. Enter a name (sensor-case2).

   3. In the Sensor Entries section, click Create New.

   4. Set the Dictionary to dic-case2, set the Count to 5, and click OK.

      

   5. Click OK to save the sensor.

3. Configure the DLP profile:

   1. Go to Security Profiles > Data Loss Prevention, select the Profiles tab, and click Create New.

   2. Enter a name (profile-case2).

   3. In the Rules section, click Create New.

   4. Configure the following settings:

      Name	1
      Sensors	sensor-case2
      Severity	Medium
      Action	Block
      Type	File
      File type	builtin-patterns
      Protocol	FTP

      

   5. Click OK.

   6. Click OK to save the profile.

4. Add the DLP profile to a firewall policy:

   1. Go to Policy & Objects > Firewall Policy and click Create New.

   2. Set the Inspection Mode to Proxy-based.

   3. In the Security Profiles section, enable DLP Profile and select profile-case2.

   4. Configure the other settings as needed.

   5. Click OK.

5. Upload a Word document that contains "demo, demo, demo, demoregexregex," using FTP.

   A DLP log is generated after the FTP traffic passes.

To log FTP upload traffic that has specific keyword, regex, and hex patterns repeated for five times in the CLI:

1. Configure the DLP dictionary:

   config dlp dictionary
       edit "dic-case2"
           config entries
               edit 1
                   set type "keyword"
                   set pattern "demo"
                   set repeat enable
               next
               edit 2
                   set type "regex"
                   set pattern "demo(regex){1,5}"
                   set repeat enable
               next
               edit 3
                   set type "hex"
                   set pattern "e6b58be8af95"
                   set repeat enable
               next
           end
       next
   end

2. Configure the DLP sensor:

   config dlp sensor
       edit "sensor-case2"
           config entries
               edit 1
                   set dictionary "dic-case2"
                   set count 5
               next
           end
       next
   end

3. Configure the DLP profile:

   config dlp profile
       edit "profile-case2"
           set feature-set proxy
           config rule
               edit 1 
                   set proto ftp
                   set filter-by sensor
                   set file-type 1
                   set sensor "sensor-case2"
                   set action block
               next
           end
       next
   end

4. Add the DLP profile to a firewall policy:

   config firewall policy
       edit 1
           set srcintf "port2"
           set dstintf "port1"
           set action accept
           set srcaddr "all"
           set dstaddr "all"
           set srcaddr6 "all"
           set dstaddr6 "all"
           set schedule "always"
           set service "ALL"
           set utm-status enable
           set inspection-mode proxy
           set profile-protocol-options "protocol"
           set ssl-ssh-profile "protocols"
           set dlp-profile "profile-case2"
           set nat enable
       next
   end

5. Upload a Word document that contains "demo, demo, demo, demoregexregex," using FTP.

   A DLP log is generated after the FTP traffic passes.
