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 […]
EEPROM (Electrically Erasable Programmable Read-Only Memory)
EEPROM (Electrically Erasable Programmable Read-Only Memory): A type of non-volatile memory used in computers and other electronic devices to store small amounts of data that must be retained without power. It can be electrically erased and reprogrammed, offering flexibility in data management, while requiring careful handling to avoid unauthorized alterations.
Entrapment
Entrapment: In a security context, entrapment refers to the strategy of tempting an attacker to commit a crime in order to catch them in the act. Unlike enticement, which involves luring an already-intent attacker, entrapment can involve creating conditions that provoke an attack that might not otherwise have occurred. This strategy can be controversial and […]
EKMS (Electronic Key Management System)
EKMS (Electronic Key Management System): A system designed to handle the generation, distribution, accounting, and destruction of cryptographic keys. As part of a robust encryption strategy, the EKMS ensures that the necessary cryptographic keys are available when needed and are kept secure at all times to prevent unauthorized access to encrypted data.
Enumeration
Enumeration: A process used in the reconnaissance or pre-attack phase where a potential attacker interacts with a system to gather information that could be useful for exploiting it. This may involve determining a user’s valid email address, network resources, shared directories, IP addresses in use, or even detailed user account information in certain circumstances.
