5.1 Scanning Overview

You want a list of all open UDP and TCP ports on your computer. You also want to know which process opened the port, which user created the process, and what time is was created. Which of the following scanning tools should you use? -Angry IP scanner -IP tools -Currports -Hping3

Currports

Which of the following packet crafting software programs can be used to modify flags and adjust other packet content? -ping -IP Tools -Colasoft -Currports

Colasoft

Randy is an ethical hacker student. He has learned how nmap flag manipulation can help find open ports. Although the name of the operating system did not jump right out at him, he might be able to figure it out by reviewing packet information. In a packet, Randy can see a TTL of 255 and a window size of 4128. What type of scanning process is Randy using? -Wardialing -Ping sweep -Beyond Trust -Fingerprinting

Fingerprinting

Alex, a security specialist, is using an Xmas tree scan. Which of the following TCP flags will be sent back if the port is closed? -FIN -RST -URG -ACK

RST

A technician is using a modem to dial a large block of phone numbers in an attempt to locate other systems connected to a modem. Which type of network scan is being used? -Stealth -Fingerprinting -Ping sweep -Wardialing

Wardialing

Which of the following flags is used by a TCP scan to direct the sending system to send buffered data? -SYN -PSH -FIN -URG

PSH

TCP is a connection-oriented protocol that uses a three-way handshake to establish a connection to a system port. Computer 1 sends a SYN packet to Computer 2. Which packet does Computer 2 send back? -SYN/RST -RST -ACK -SYN/ACK

SYN/ACK

Which of the following best describes the scan with ACK evasion method? -Sends packets and breaks them apart so intrusion detection systems don't know what they are. -Returns feedback to the fake IP address and ensures there is no record of the IP address sending the requests. -Helps determine whether the firewall is stateful or stateless and whether or not the ports are open. -Filters incoming and outgoing traffic, provides you with anonymity, and shields you from possible detection.

Helps determine whether the firewall is stateful or stateless and whether or not the ports are open.

Which of the following scans is used to actively engage a target in an attempt to gather information about it? -Port scan -Vulnerability scan -TCP scan -Network scan

Port scan

A hacker finds a target machine but wants to avoid getting caught, so the hacker finds another system to take the blame. This system is frequently called a zombie machine because it's disposable and creates a good distraction. Which of the following port scans is being used? -Xmas tree scan -NULL scan -Full open scan -Idle scan

Idle scan

A ping sweep is used to scan a range of IP addresses to look for live systems. A ping sweep can also alert a security system, which could result in an alarm being triggered or an attempt being blocked. Which type of scan is being used? -Port scan -Decoy scan -Network scan -Vulnerability scan

Network scan

You are using an iOS device. You want to scan networks, websites, and ports to find open network devices. Which of the following network mapping tools should you use? -NetAuditor -Colasoft -Network Topology Manager -Scany

Scany

What type of scan is used to find system weaknesses such as open ports, access points, and other potential threats? -Vulnerability scan -Port scan -Decoy scan -Network scan

Vulnerability scan

Which of the following is a benefit of using a proxy when you find that your scanning attempts are being blocked? -As long as you are not bombarding the system, the packet segments float by without concern. -The scan is sent to the recipient, the feedback is returned to the fake IP address, and then there is no record of your IP address sending the requests. -This scan will help you to determine whether the firewall is stateful or stateless and whether or not the ports are open. -It filters incoming and outgoing traffic, provides you with anonymity, and shields you from detection.
