Note. Consider changing the cell in yellow, does not make sense, it could be 10100 instead of 1010
Hi, to design this sheet, I also used the and(...) function of MS excel, in which you declate that in order to select a certain answer, 2 or more conditions must be true, in our case, if a purchase is up to 1000, the price would be $1010 (consider changing this value, maybe to 10100), if the purchase is more than 1000 and less than 5000, the price is $9,509.50, and if is more than 5000 units, the price would be $5,5005.50.
Please check the formula for further clarifications.
Best of luck.
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.
