Ethernet
Ethernet: A networking technology used for local, metropolitan, and wide area networks, initially developed by Xerox in the 1970s and standardized by IEEE as IEEE 802.3. Ethernet allows devices to communicate over wired data networks using physical cables and switches, facilitating data packet exchange between computers, printers, and other devices. It has evolved to support […]
Evil Twin
Evil Twin: A rogue Wi-Fi access point that appears legitimate to users but is actually set up by an attacker to intercept wireless communications. The evil twin may mimic the name and settings of a legitimate access point to trick users into connecting to it, allowing the attacker to eavesdrop or manipulate their network traffic.
Executable Code
Executable Code: This refers to a set of instructions in a computer program that is currently being executed or is ready to be run by a computer’s processor. Executable code can come in various forms, such as binary executable files, scripts, or sequences of instructions interpreted by an interpreter. It typically resides within an executable […]
Executive state
Executive state: The operating status of a system when it is executing its primary, user-oriented functions, rather than administrative or maintenance tasks. Ensuring security while the system processes and manages data in this state is critical.
Exercise Key
Exercise Key: An exercise key is a temporary cryptographic key used in communications systems during exercises or system testing. This key is employed to protect sensitive data but is not intended for operational use. The purpose is to validate the operational readiness of a system without impacting real-world operations or revealing actual operational keys.
Exfiltration
Exfiltration: The unauthorized transfer of data from a computer or other device to an external location or party. In cybersecurity, it often refers to data being illicitly copied or transmitted out of a network by an attacker or malware. Exfiltration can result in significant privacy breaches, intellectual property theft, and security incidents. Preventing exfiltration is […]
