Attackers frequently use ACK scans to circumvent a firewall or other filtering tools. During a NULL scan, all packet flags are enabled. The most recent versions of Nessus Server and Client are compatible with Windows, Mac OS X, FreeBSD, and the vast majority of Linux variants.

<h3>What is ack scan ?</h3>
  • ACK scans are used to identify hosts or ports that have been blocked or are resistant to other types of scanning. An attacker uses TCP ACK segments to learn about firewall or ACL configuration.
  • Attackers probe our router or send unsolicited SYN, ACK, and FIN requests to specific UDP/TCP ports.
  • TCP ACK Scan sends an ACK message to the target port to determine whether or not it is filtered.
  • On unfiltered ports, a RST reply packet will be sent for both open and closed ports. Filtered ports will either generate no response or generate an ICMP reply packet with an unreachable destination.
  • The TCP ACK scanning technique attempts to determine whether a port is filtered by using packets with the ACK flag set.

Suppose you want your firewall to block all incoming Telnet connections but to allow outbound Telnet connections. One approach w
Vera_Pavlovna [14]

Answer:

Another way to block all inbound packets is to use the firewall layer of the circuit.

Explanation:

The firewall circuit layer is a firewall containing a table with four fields, mainly such as source port, destination port, source IP address, and destination IP address.

They are containing mainly the addresses or the ports that need to be blocked.   So we want to block all inbound packets, and also set the source port to 23 while the rest is set to zero, meaning that all inbound packets are blocked.

  7. wordBlue = "Blue"     = FALSE
  8. numberRed <= numberGreen  = TRUE
  9. numberBlue >= 200    = TRUE
  10. numberGreen >= numberRed + numberBlue = TRUE
  11. numberRed > numberBlue AND numberBlue < numberGreen = FALSE
  12. numberRed = 100 OR numberRed > numberBlue   = TRUE
  13. numberGreen < 10 OR numberBlue > 10     = FALSE
  14. numberBlue = 30 AND numberGreen = 300 OR numberRed = 200 = FALSE

input_month = input()

input_day = int(input())

months= ('January', 'February','March', 'April' , 'May' , 'June' , 'July' , 'August' , 'September' , "October" , "November" , "December")

if not(input_month in months):

  print("Invalid")

elif input_month == 'March':

   if not(1<=input_day<=31):

       print ("Invalid")

   elif input_day<=19:

       print("Winter")

   else:

      print ("Spring")

elif input_month == 'April' :

   if not(1<=input_day<=30):

       print("Invalid")

   else:
