Thedigcommand in Linux is used for DNS troubleshooting. It queries DNS records and provides detailed information about domain name resolutions.

traceroutetracks the path packets take to a destination but does not diagnose DNS.

netstatlists active connections, not DNS records.

ifconfigis used for managing network interfaces.

Availabilityensures that systems, applications, and data remain accessible and operational for authorized users when needed. Organizations implement redundancy, failover mechanisms, and backup systems to maintain availability.

Integrityensures that data remains accurate and unchanged.

Confidentialityprotects sensitive data from unauthorized access.

Innovationis not a component of the CIA triad.

Alaunch point attackoccurs when an attacker compromises a system and uses it as a foothold to spread malware, conduct reconnaissance, or launch further attacks against other systems. Botnets and command-and-control (C2) servers operate this way.

Denial of availabilitydisrupts service, but does not spread attacks.

Data exportsteals data instead of launching further attacks.

Data modificationchanges existing information but does not involve propagating threats.

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.

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.
