    • nmap -sX 192.168.1.254
    • nmap -sV 192.168.1.254
  4. As an Ethical Hacker you are capturing traffic from your customer network with Wireshark and you need to find and verify just SMTP traffic. What command in Wireshark will help you to find this kind of traffic?

  6. In IPv6 what is the major difference concerning application layer vulnerabilities compared to IPv4?

    • Vulnerabilities in the application layer are independent of the network layer. Attacks and mitigation techniques are almost identical.
    • Due to the extensive security measures built in IPv6, application layer vulnerabilities need not be addresses.
    • Vulnerabilities in the application layer are greatly different from IPv4.
  7. In which phase of the ethical hacking process can Google hacking be employed? This is a technique that involves manipulating a search string with specific operators to search for vulnerabilities.

  9. ……..is an attack type for a rogue Wi-Fi access point that appears to be a legitimate one offered on the premises, but actually has been set up to eavesdrop on wireless communications. It is the wireless version of the phishing scam. An attacker fools wireless users into connecting a laptop or mobile phone to a tainted hotspot by posing as a legitimate provider. This type of attack may be used to steal the passwords of unsuspecting users by either snooping the communication link or by phishing, which involves setting up a fraudulent web site and luring people there.
