Spoofing
Spoofing: The act of impersonating another entity to gain unauthorized access to systems or trick users into revealing sensitive information. Common examples include email spoofing for phishing attacks and IP address spoofing to bypass network security measures.
Snooping
Snooping: An invasive activity where an unauthorized person observes or intercepts private communication in a network, often to gain access to confidential information. While similar to sniffing, snooping is more commonly used to refer to passive listening and is considered a security risk.
SPOOL (Simultaneous Peripheral Operations Online)
SPOOL (Simultaneous Peripheral Operations Online): A computing process where data is temporarily stored to be processed or output sequentially. Commonly associated with print spooling, it allows a computer to receive multiple print jobs at once, which are then queued and sent to the printer or another output device in the order they were received.
Shell
Shell: A command-line interface for accessing an operating system’s services. It is used to perform tasks and manage system resources through the use of commands and scripts. Examples include the Bash shell on Linux systems and the PowerShell on Windows systems.
Shimmer
Shimmer: A type of skimming device that is inserted into a card slot, such as those on ATMs or point-of-sale terminals, to read data from chip-based credit and debit cards. Unlike traditional skimmers, shimmers are thinner and target the chip instead of the magnetic stripe, making them harder to detect.
Side Channel Attacks
Side Channel Attacks: Security attacks that exploit indirect information gained from a system’s implementation, such as power consumption or electromagnetic emissions, to compromise the system. While side-channel attacks can occur in various environments, including virtualized systems, they are not exclusive to virtualization and can affect physical hardware as well.
