A broadband router is a type of network router that connects multiple computers within a local network while also providing internet access. It functions as a gateway between the local network and the internet by handling data packet transmission and routing. Broadband routers are widely used in small offices and homes because they offer essential networking services, including DHCP, NAT, and sometimes wireless connectivity.

Inter-provider border routers are used by ISPs to route data between different providers and do not serve as an internet gateway for end users.

Subscriber edge routers are typically deployed at the edge of an ISP's network to connect subscriber networks but do not provide full internet routing functionalities.

Core routers operate at the backbone level of a network, facilitating high-speed data transfer but not connecting end-user devices directly.

Server-side validation helps prevent SQL injection, command injection, and other input-based attacks by ensuring that user input is properly sanitized before being processed by the system. Parameterized queries and input validation should also be implemented to further reduce risk.

Detecting code vulnerabilities is helpful but not a direct mitigation technique.

Decreasing wireless range does not affect injection attacks.

Using WPA2 secures wireless networks but does not prevent injection attacks.

Multifactor authentication (MFA) requires users to verify their identity using multiple factors, such as something they know (password), something they have (a token or phone), or somewhere they are (geolocation-based access control). Requiring both location verification and password authentication demonstrates MFA.

Certificate verification checks digital certificates for security but does not use multiple authentication factors.

User-based accounting logs user activities but does not verify identity.

Single sign-on (SSO) allows access to multiple systems with one login but is not necessarily MFA.

Phishing is 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 spoofing disguises a system's identity but does not involve email deception.

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

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

The netstat command in Linux displays active network connections, listening ports, and network statistics. It is useful for diagnosing network issues and identifying open connections.

nslookup is for DNS queries.

dig provides DNS information, not network connection status.

ifconfig shows network interface details but does not list active connections.
