      DDoS, or distributed denial of service, attacks are used to disrupt service by overwhelming network devices with bogus traffic.
  2. Which tool can perform real-time traffic and port analysis, and can also detect port scans, fingerprinting and buffer overflow attacks?

    • Nmap
    • Netflow
    • SIEM
    • Snort
      Answers Explanation & Hints:

      Snort is an open source intrusion protection system (IPS) that is capable of performing real-time traffic and port analysis, packet logging, content searching and matching, as well as detecting probes, attacks, port scans, fingerprinting, and buffer overflow attacks.
  3. Which tool can identify malicious traffic by comparing packet contents to known attack signatures?

    • Zenmap
    • Netflow
    • IDS
    • Nmap
      Answers Explanation & Hints:

      An IDS, or intrusion detection system, is a device that can scan packets and compare them to a set of rules or attack signatures. If the packets match attack signatures, then the IDS can create an alert and log the detection.

    • remote control of the target device
    • malicious action
    • creation of malicious payload
    • gathering target information
      Answers Explanation & Hints:

      The Cyber Kill Chain describes the phases of a progressive cyberattack operation. The phases include the following:

      *Command and control
      *Actions on objectives

      In general, these phases are carried out in sequence. However, during an attack, several phases can be carried out simultaneously, especially if multiple attackers or groups are involved.

  5. Which protocol is used by the Cisco Cyberthreat Defense Solution to collect information about the traffic that is traversing the network?

    • NAT
    • Telnet
    • NetFlow
    • HTTPS
