Which of the following BEST explains why a penetration tester cannot scan a server that was previously scanned successfully?
Which of the following BEST explains why a penetration tester cannot scan a server that was previously scanned successfully?
The most likely reason a penetration tester cannot scan a server that was previously scanned successfully is that the IP address is on the blocklist. Blocklists are used to prevent access from IP addresses that are considered suspicious or have been identified as sources of unwanted activity. If the penetration tester's IP address has been added to a blocklist, it would prevent any further scanning attempts from that address.
The BEST explanation for why a penetration tester cannot scan a server that was previously scanned successfully is that the IP address is on the blocklist. Blocklists are used by firewalls and other security measures to restrict access to certain IP addresses or ranges of IP addresses. If an IP address is on the blocklist, it will not be able to be scanned by a penetration tester.
ccccccccccccccccc
Chicken-Egg here: If the IP is on a blocklist, then by default isn't it unreachable? So C can cause B, so B could still be a "correct" answer. Hmmmm....
Agreed. I'm thinking why in the world would anyone block a Server IP? I understand any security system might block the attacker machine IP.
But which IP are we talking about here. If the server is isolated from network then the correct term should not be blocking but segmentation, isn't it?
Option C, "The IP address is on the blocklist," is the most relevant explanation in this context. Blocklists are commonly used to restrict access from specific IP addresses that might be considered suspicious or have been identified as sources of malicious activity. If the server has detected scanning activity from the penetration tester's IP address and considered it hostile, it could have added the IP address to a blocklist, subsequently preventing further scans from that address.
C is correct The most likely explanation for why a penetration tester cannot scan a server that was previously scanned successfully is that the IP address is on the blocklist. Blocklists are used to prevent malicious actors from scanning servers, and if the IP address of the server is on the blocklist, the scanning process will be blocked.
C is the correct answer after search
I think B is correct
Please comments your on other new questions its very help full to all your idea is very importent
Please only comment if you actaully have a clue what you're on about
I think option C is best, unlikely a server is unreachable.
Another horribly written question. It is not specifying which IP is on the blocklist. The attacker machine or the server. Why in the world would any WAF block your server's IP due to an attacker scanning it. That is dumb. If anything, the attacker machine's IP would end up on the blocklist. But again, who's blocklist? The server's? a router? a firewall? I honestly don't know how to answer this question.
Option C, "The IP address is on the blaocklist"
the best is C
There could be several reasons why a penetration tester cannot scan a server that was previously scanned successfully. One possible reason could be that the IP address of the server is on the blocklist, which means that the organization's security measures have blocked access from the penetration tester's scanning tool. Another possible reason could be that the server's IP address has changed since the last scan, making it unreachable or belonging to a different device. Therefore, option C is the BEST explanation for this scenario.
