Honey Account
Detection Engineering
A honey account is a decoy user account placed inside a real identity store, such as Active Directory, and monitored so that any use of it raises an alert.
Honeypot
Threat IntelligenceDetection EngineeringThreat Hunting
A honeypot is a deliberately deployed decoy system, server, or network resource designed to lure attackers away from real production assets, expose their tactics, and generate actionable threat intelligence. Unlike perimeter controls that block threats at the gate, a honeypot lets an attacker inside a controlled, isolated trap and then watches everything they do.
Honeypots
Detection EngineeringThreat Hunting
A honeypot is a cybersecurity mechanism that uses a manufactured, decoy attack target to lure attackers away from legitimate systems and record how they operate.
Honeytokens
Detection EngineeringThreat Hunting
A honeytoken is a fake credential, file, record, or token planted among real assets, with no legitimate use, that fires an alert the moment anyone accesses it.
How Does Ransomware Spread
Threat IntelligenceDetection Engineering
Ransomware spreads in two phases: it gains a foothold through vectors like phishing or exposed RDP, then propagates across the network with stolen credentials and lateral movement.

Identity and Access Management (IAM) is the framework of policies, processes, and technology that governs digital identities and controls their access to systems, applications, and data.
Identity-Based Attacks
Threat IntelligenceDetection Engineering
An identity-based attack is a cyberattack that targets credentials and authentication (passwords, hashes, Kerberos tickets, and session tokens) to gain access to systems and data as a legitimate user.
Identity Governance and Administration (IGA)
Detection EngineeringEndpoint Forensics
Identity governance and administration (IGA) is the framework for managing digital identities and their access across the full lifecycle, and governing that access so it stays appropriate, least-privilege, and auditable.

Detection EngineeringThreat Hunting
Identity monitoring is the continuous analysis of authentication activity, access behavior, and privilege change to detect identity-based threats.
Identity Provider (IdP) Security
Detection EngineeringThreat Hunting
Identity provider (IdP) security is the practice of protecting the service that authenticates users and issues the signed tokens every connected application trusts.
Identity Security
Detection EngineeringThreat Hunting
Identity security, also called identity protection, is the practice of protecting accounts, credentials, and entitlements from being stolen, abused, or escalated, and detecting when they are.
Identity Security Posture Management (ISPM)
Detection EngineeringThreat Hunting
Identity Security Posture Management (ISPM) is a continuous practice of assessing and hardening an organization's identity infrastructure (accounts, access rights, and authentication) to prevent identity-based breaches.
Identity Segmentation
Detection EngineeringThreat Hunting
Identity segmentation restricts access to applications and resources based on the identity making the request and how it behaves, rather than the network it sits on.
Identity Theft Prevention Strategies
Threat IntelligenceDetection Engineering
Identity theft prevention is the set of strategies that make stolen personal information hard to use, from phishing-resistant authentication to monitoring and credit freezes.
Identity Threat Detection and Response (ITDR)
Detection EngineeringThreat Hunting
Identity threat detection and response (ITDR) is the discipline that detects, investigates, and stops attacks abusing identities, credentials, and directories.
IIS Logs
Detection EngineeringEndpoint Forensics
An IIS log is the access record Internet Information Services writes for a Windows web server, one line per HTTP request, capturing who connected, what they requested, and how the server answered.
Incident Responder
Detection EngineeringThreat Hunting
An incident responder is a security professional who investigates, contains, and remediates security incidents, taking a confirmed or suspected breach and driving it to closure while preserving evidence.
Incident Response
Malware AnalysisThreat IntelligenceNetwork ForensicsCloud ForensicsEndpoint Forensics
Incident response is the organized process a team uses to detect, contain, and recover from a cyberattack, combining a written plan, a trained team, and a repeatable set of steps to limit the damage.
Incident Response Plan
Detection EngineeringThreat Hunting
Incident response steps are the ordered phases a team runs to take a security incident from first alert to closure: preparation, identification, containment, eradication, recovery, and lessons learned.
Indicators of Attack (IOAs)
Threat Intelligence
An indicator of attack (IOA) is evidence of the intent and behavior behind an attack, the sequence of actions an adversary must take to reach their goal, observed in real time while the attack is happening.
Indicators of Compromise (IOC)
Threat Intelligence
An indicator of compromise (IOC) is a piece of forensic evidence, such as a file hash, malicious IP, callback domain, or registry change, that suggests an endpoint or network has been breached.
Indicators of Compromise (IOCs)
Threat IntelligenceDetection EngineeringThreat Hunting
An Indicator of Compromise (IOC) is a piece of forensic evidence that signals a network, endpoint, or system has likely been breached. Unlike a warning that an attack *might* occur, an IOC is evidence that one *already has*Â whether through malware installation, unauthorized access, credential theft, or data exfiltration.
