TCP/IP is a suite of communication protocols that enable data to be exchanged between interconnected devices over the internet and other computer networks.


Takedown is the act of removing a website or other online content from the internet, often due to a violation of laws or policies.


Tailgating is the practice of following closely behind another person to gain unauthorized access to a restricted area, often used as a method of social engineering to bypass physical security controls.

TACACS+ (Terminal Access Controller Access-Control System Plus)

TACACS+ is a security protocol that provides centralized authentication, authorization, and accounting services for remote access devices.

Threat Hunting

Threat hunting is a proactive approach to identifying and mitigating threats to an organization’s security infrastructure by actively searching for and analyzing suspicious activities or behavior.

Threat Intelligence

Threat intelligence is the process of collecting and analyzing information about potential or current cyber threats to identify risks and enhance an organization’s security posture.

Threat Model

A threat model is a systematic approach to identifying and assessing potential security threats to a system or application and developing measures to mitigate those risks.

Threat Vector

A threat vector is the means by which a cyberattack or other security threat can gain access to a system or network, such as through phishing emails, infected websites, or unsecured devices.

TLS (Transport Layer Security)

TLS is a cryptographic protocol that provides secure communication over the internet and other computer networks, commonly used to secure data transmission for online transactions and other sensitive information.


Tokenization is the process of replacing sensitive data with a non-sensitive equivalent, such as a randomly generated number, to reduce the risk of data breaches or unauthorized access.

Tor Network

The Tor network is a decentralized network of servers and nodes designed to provide anonymous internet access and protect the privacy and security of users.


Traceroute is a command-line tool used to trace the path that network packets take between a source and destination device, often used to troubleshoot network connectivity issues.

Trap and Trace

Trap and trace is a legal process that allows law enforcement agencies to monitor and record internet traffic to identify and investigate criminal activity.

Trojan Horse

A Trojan horse is a type of malware that appears to be legitimate software but is designed to harm a computer system or network by allowing unauthorized access or stealing sensitive data.

Trust Model

A trust model is a framework for establishing and managing trust relationships between entities in a system, often used in the design of secure computer systems and networks.

Trust Zone

A trust zone is a secure area of a computer system or network that is designated as a trusted environment for running critical or sensitive applications.

Two-Factor Authentication (2FA)

Two-factor authentication is a security process that requires users to provide two forms of identification, such as a password and a security token or biometric authentication, to access a system or application.

Temporal Key Integrity Protocol (TKIP)

Temporal Key Integrity Protocol is a wireless security protocol used to secure data transmission over Wi-Fi networks, providing stronger encryption and protection against key attacks.

Third-Party Access

Third-party access refers to the practice of granting access to a computer system or network to individuals or organizations that are not part of the organization that owns the system or network.


Tunneling is a technique used to encapsulate one network protocol within another, allowing data to be transmitted securely over a public network such as the internet.


A transcript is a written or typed copy of a spoken conversation or presentation, often used in legal and academic settings.

In cybersecurity, transcripts of communications may be reviewed as part of incident response or forensic investigations.

Transcripts of training sessions and simulations may be used to assess the knowledge and skills of (security) personnel.
