Phishingis a cyberattack where attackers impersonate legitimate entities (e.g., banks, companies) and send fraudulent emails or messages designed to trick recipients into revealing sensitive information, such as usernames, passwords, or financial details. The fake link in the email directs victims to a malicious site that captures their credentials.

IP address spoofingdisguises a system’s identity but does not involve email deception.

Session hijackingtakes over an active session but does not involve email scams.

Man-in-the-middle attackintercepts communication rather than tricking users via emails.

TheTransport layerin the TCP/IP model includes theUser Datagram Protocol (UDP)andTransmission Control Protocol (TCP). UDP is a connectionless protocol used for fast, lightweight data transmission where reliability is not the priority (e.g., video streaming, VoIP).

Application layerhandles end-user services but not transport mechanisms.

Network or internet layerdeals with IP addressing and routing, not UDP.

Physical or network access layerconcerns hardware transmission methods.

Server-side validationhelps preventSQL injection, command injection, and other input-based attacksby ensuring that user input is properly sanitized before being processed by the system.Parameterized queries and input validationshould also be implemented to further reduce risk.

Detecting code vulnerabilitiesis helpful but not a direct mitigation technique.

Decreasing wireless rangedoes not affect injection attacks.

Using WPA2secures wireless networks but does not prevent injection attacks.

Anaccess point (AP)is a network device that extends the coverage of a wireless network by acting as a bridge between wired and wireless devices. It allows users to connect to a network without needing a direct wired connection. APs are particularly useful in large office spaces where Wi-Fi signals may not reach all areas.

Routersprimarily manage network traffic but do not directly extend network range unless they include built-in AP functionality.

Serversare used for hosting applications and storing data but do not extend network connectivity.

Switchesconnect wired devices within a local network but do not extend wireless network range.

Awireless routeris designed to create an access point that allows wireless devices to connect to a network. It combines the functions of a traditional router with a wireless access point, enabling communication between wired and wireless devices. These routers use Wi-Fi standards (e.g., 802.11ac, 802.11ax) to transmit data wirelessly.

Broadband routersprimarily provide internet connectivity but do not necessarily include Wi-Fi functionality unless specified.

Core routershandle large-scale data routing in the backbone of networks but are not designed for access point creation.

Inter-provider border routersfunction at an ISP level for routing traffic between different networks, not for providing user access.
