A. Agent-based scanner Module 05/P561 CEH bookV12 *Network-Based Scanner: Network-based scanners are those that interact only with the real machine where they reside and give the report to the same machine after scanning. *Agent-Based Scanner: Agent-based scanners reside on a single machine but can scan several machines on the same network. *Proxy Scanner: Proxy scanners are the network-based scanners that can scan networks from any machine on the network. * Cluster scanner: Cluster scanners are similar to proxy scanners, but they can simultaneously perform two or more scans on different machines in the network.

B. Network-based scanner Explanation: In the given scenario, John employs a network-based scanner to identify vulnerabilities on the machines in the same network. A network-based scanner is a type of vulnerability assessment tool that scans the network for vulnerabilities and identifies security holes in the network devices and systems. It is a non-intrusive scanner that can detect vulnerabilities without accessing the system. It sends packets to the network and analyzes the response to identify vulnerabilities.

I think that it is answer A, because it says that the attacker installs the scanner on a single machine to scan other machines on the same network.

Listed below are some of the location and data examination tools: o Network-Based Scanner: Network-based scanners are those that interact only with the real machine where they reside and give the report to the same machine after scanning. o Agent-Based Scanner: Agent-based scanners reside on a single machine but can scan several machines on the same network. o Proxy Scanner: Proxy scanners are the network-based scanners that can scan networks from any machine on the network. o Cluster scanner: Cluster scanners are similar to proxy scanners, but they can simultaneously perform two or more scans on different machines in the network

The most appropriate choice is: B. Network-based scanner. Explanation: Agent-based scanner: This typically involves installing software agents on each target machine to perform vulnerability assessments. It doesn't fit the scenario where a scanner is installed on one machine and used to scan others. Network-based scanner: This is a scanner that examines network traffic or directly probes other machines on the network to identify vulnerabilities. It matches the scenario where a scanner was installed on a machine and used to scan other machines on the same network. Cluster scanner: This is less commonly referred to in the context of vulnerability assessment tools and usually pertains to managing and scanning clusters of machines, but not in the specific way described. Proxy scanner: This typically involves using a proxy to scan web traffic, and is not relevant to the scenario described.

I Believe the answer is B as I understand how you are using the key word install, to run an agent-based scan all the machines involved need have the agent installed on them to do the scan, while network scan requires connectivity, and this scenario I do not think the attacker has access to any other device to install the agents.

Though the scanner software was installed on a victims machine... Actually a network based scanner is being performed to identify vulnerabilities on the network and on the other machines. Agent based scanner would be installed a on machine BUT will send information about THAT machine to a central repo. This is not happening in this scenario.

My answer is network-base scanner. Reason 1: although an "agent" is installed on a victim machine, there is no mention of using this scanner to scan for vulnerability on this victim machine. Reason 2: The "agent" was used to scan on machines within the network, this fits the signature of a "network-based scanner"

A. Agent based. "installed a scanner on a machine" keyword is on a machine.

GPT4: B. Network-based scanner In the scenario described, the professional hacker is using a network-based scanner. This type of scanner is deployed on a network and scans multiple machines on that network to identify potential vulnerabilities without being installed on each individual machine. Network-based scanners are commonly used to assess security posture and identify vulnerabilities that could be exploited.

In the scenario described, where the hacker installed a scanner on a machine within the victim's network and scanned several machines on the same network, it aligns more closely with an Agent-Based Scanner. Agent-based scanners reside on a single machine but can scan several machines on the same network.

None-of-the-above would have been my answer. John didn't employ anything (himself).
