When testing firewall security, which type of tool stresses a system to discover if it will react improperly, fail, or reveal unknown vulnerabilities

Fuzzing

Explanation:

A firewall is a network security protocol that monitors and controls inbound and outbound traffic based on set aside security rules.

Generally, a firewall is used to control access to a computer or network, as it creates a barrier between a computer or a network and the internet in order to protect against unauthorized access. It is a security system pre-installed on most computers to essentially inspect data being transmitted to or from a computer.

Furthermore, firewalls are typically bidirectional, it checks all sent and received data and only allow authorized traffic through.

Fuzzing also referred to as fuzz testing can be defined as a software testing technique or method which typically involves inputting invalid, random or unexpected data into a computer system or software application so as to test, discover, and assess their security strength.

Hence, when testing a firewall security, fuzzing tool stresses a system to discover if it will react improperly, fail, or reveal unknown vulnerabilities (bugs) that could be exploited by unauthorized users such as a hacker.

solution:

this situation is called an ip conflict.

data from a server is sent in small bits called packets. in an ip conflict, some packets will end up in one computer while some other packets will end up in another computer.

so…overall none of the computers get the data as the original message or picture being sent by the server cannot be retrieved with only half the packets. so it will show up as an error.

thus the final answer is d.
