What type of attack disrupts services by overwhelming network devices with bogus traffic?Question 3Select one:port scansDDoSbrute forcezero-day

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 facilitates the encryption of traffic between the attacker and the target device, ensuring the attacker's activities remain undetectedIt directly provides the attacker with administrative access to network devices by exploiting default port configurations.It allows the attacker to overload the network device by opening too many connections, causing a denial of service.It enables the identification of active services and potential vulnerabilities associated with open ports on the target device.
