What is the purpose of a port scan in ethical hacking? To identify open network ports To exploit vulnerabilities in network services To gain unauthorized access to a system To perform a denial-of-service attack

In the context of network security, port scanning is a technique used by both security professionals and potential attackers to identify open ports on a networked device. Why is port scanning considered a critical preliminary step in the reconnaissance phase of a cyber-attack? Group of answer choicesIt directly provides the attacker with administrative access to network devices by exploiting default port configurations.It facilitates the encryption of traffic between the attacker and the target device, ensuring the attacker's activities remain undetectedIt enables the identification of active services and potential vulnerabilities associated with open ports on the target device.It allows the attacker to overload the network device by opening too many connections, causing a denial of service.
