Tape Management System (TMS): A software or hardware solution that manages the storage, organization, and retrieval of data on tape media. It is commonly used in large-scale data backup and recovery operations, where tapes are used as a long-term storage medium. Examples include tape libraries, tape robots, and tape cataloging systems.

Target: A specific entity or system that is the focus of an attack or a security measure. It is a common term in the field of cybersecurity, where targets can include individuals, organizations, networks, or devices. Examples include targeting a specific individual's email account for a phishing attack or targeting a company's network for a ransomware attack.

Tcpdump: An open-source command-line tool used primarily on Unix and Linux-based systems for network monitoring and data analysis. It allows the user to intercept and display TCP/IP and other packets transmitted or received over a network to which the computer is attached. In terms of security, tcpdump can be used for analyzing network activity, troubleshooting network issues, and detecting network intrusion attempts or other suspicious activity.

TCP/IP Hijacking: An attack where an intruder takes control of an existing TCP/IP session between two entities. The attacker exploits vulnerabilities to insert themselves into the data stream, enabling them to intercept or manipulate the communication. This form of hijacking poses significant risks to data integrity and confidentiality.

TCP/IP (Transmission Control Protocol/Internet Protocol): The suite of protocols that defines how devices communicate over networks, including the internet. TCP (Transmission Control Protocol) and IP (Internet Protocol) are the two primary protocols in the suite and are responsible for establishing connections, transmitting data, and routing packets across networks. Examples include using TCP/IP to send an email, to access a website, or to share files over a network.

TCP Sequence Number Prediction Attack: A cyberattack exploiting the sequential nature of TCP packets. Attackers predict the sequence numbers used in a TCP session to inject malicious data or take over the connection. This technique can compromise the session's integrity, potentially leading to data breaches or service disruptions. One defense to this is to randomize the sequence number, versus having them created in a basic chronological order.
