Because UDP is a connectionless protocol, unlike TCP, which initiates a "three-handshake" to establish a connection, UDP scanning must rely on ICMP "port unreachable" messages to determine if a port is open. When the scanner sends out a UDP packet, if the target system is not listening to the corresponding UDP port, it will respond with an ICMP "port unreachable" message. 3.The Do phishing attack is specifically based on an attacker providing a user with a malicious link to a seemingly valid and trusted resource. Once the link is clicked, the user receives a prompt to reveal their confidential information, for example, a prompt to enter a username and password.4. C. A backdoor is an application or code that an attacker can use to gain greater access or to gather information needed to launch further attacks.5. bo amplification attack is a form of reflection attack that generates far more response traffic (sent by a host unknowingly participating in the attack) than the traffic initially sent by the attacker (who tricks the victim).6. do A cache overflow occurs when a program or software places an excessive amount of data into the cache, or when a program attempts to place data in more memory locations than are cached. An attacker creates a cache overflow to allow data outside the boundaries of an allocated block of memory to corrupt other data thatA.1 Mapping quiz answers 517or crash the program/operating system. In the worst case scenario, this could lead to the execution of malicious code.7. ao XSS is a Web application vulnerability through which an attacker can inject malicious scripts into a legitimate, trusted Web site. An attacker could use a Web application to launch an attack against an XSS vulnerability, sending malicious code, typically in the form of browser-side scripts, to a large number of end users. 8.
