Event Type: The categorization of security events based on their nature or characteristics. Event types might include login events, file change events, network traffic events, and more. These categories assist in the analysis of events, helping security professionals to identify trends, spot anomalies, and understand the broader context of security events within a system or network.

Evidence: Information presented to support the truth or existence of an assertion. In legal contexts, evidence includes testimony, documents, and objects admissible in court to prove or disprove allegations. In science, evidence consists of collected data and observations that support or refute hypotheses. In cybersecurity, it comprises digital records and activities that indicate the security posture of systems or that a security incident has occurred.

Evil Twin: A rogue Wi-Fi access point that appears legitimate to users but is actually set up by an attacker to intercept wireless communications. The evil twin may mimic the name and settings of a legitimate access point to trick users into connecting to it, allowing the attacker to eavesdrop or manipulate their network traffic.

Exception reports: Documents generated when a process or operation deviates from its predefined norm or standard. In the security realm, these are vital in identifying anomalies such as unauthorized access attempts, failed login attempts, or other forms of unusual system activities that could indicate a security threat.

Executable Code: This refers to a set of instructions in a computer program that is currently being executed or is ready to be run by a computer's processor. Executable code can come in various forms, such as binary executable files, scripts, or sequences of instructions interpreted by an interpreter. It typically resides within an executable file, which can be a standalone program or part of a larger application, and is responsible for performing specific tasks or operating various functions within a software environment.

Executive state: The operating status of a system when it is executing its primary, user-oriented functions, rather than administrative or maintenance tasks. Ensuring security while the system processes and manages data in this state is critical.
