Discussion-based security drills where teams review response procedures for hypothetical incident scenarios. Tabletop exercises test plan effectiveness, identify gaps, and improve coordination without deploying technical resources or disrupting operations.

Cyberspace environments that dynamically adjust security controls based on user context, threat levels, and risk conditions. Adaptive security mechanisms automatically increase protection when suspicious activity is detected.

Any circumstance, event, or actor with potential to exploit vulnerabilities and cause harm to systems, data, operations, or individuals. Threats include natural disasters, human error, malicious attacks, and system failures.

Individuals, groups, organizations, or governments conducting or planning malicious activities against information systems. Threat actors range from script kiddies to sophisticated nation-state operations with varying motivations and capabilities.

Identifying and assessing adversary capabilities, tactics, and objectives to support security operations and investigations. Threat analysis combines intelligence gathering with behavioral assessment to predict and counter malicious activities.

The systematic evaluation of potential threats to determine their likelihood and impact on organizational operations. Assessment prioritizes threats based on risk severity, enabling appropriate resource allocation for mitigation.

All potential entry points and vulnerabilities attackers could exploit to compromise systems or data. Reducing threat surface involves eliminating unnecessary services, closing ports, removing unused applications, and limiting access.

An authentication credential combining identity verification data with temporary encryption keys to establish trusted sessions. Tickets enable single sign-on and secure service access without repeatedly entering credentials.

A color-coded system (RED, AMBER, GREEN, WHITE) designating information sharing restrictions to ensure sensitive data reaches only authorized audiences. Protocol colors indicate whether information can be shared publicly or remains confidential.

Malicious software disguised as legitimate applications that performs hidden harmful functions while appearing useful. Trojans bypass security by exploiting user trust, often delivering additional malware or creating backdoors.
