TCP ACK Firewall Scanner



Map out firewall rulesets with a raw ACK scan. Any unfiltered ports found means a stateful firewall is not in place for them.

Module Options

To display the available options, load the module within the Metasploit console and run the commands 'show options' or 'show advanced':

msf > use auxiliary/scanner/portscan/ack
msf auxiliary(ack) > show actions
msf auxiliary(ack) > set ACTION < action-name >
msf auxiliary(ack) > show options
    ...show and set options...
msf auxiliary(ack) > run 

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
