An example of an IDN homograph attack; the Latin letters "e" and "a" are replaced with the Cyrillic letters "е" and "а".The internationalized domain name (IDN) homograph attack (sometimes written as homoglyph attack) is a method used by malicious parties to deceive computer users about what remote system they are communicating with, by exploiting the fact that many different characters look ...
A cyberattack is any type of offensive maneuver employed by individuals or whole organizations that targets computer information systems, infrastructures, computer networks, and/or personal computer devices by various means of malicious acts usually originating from an anonymous source that either steals, alters, or destroys a specified target by hacking into a susceptible system.
The resulting representation was called "attack trees." In 1998 Bruce Schneier published his analysis of cyber risks utilizing attack trees in his paper entitled "Toward a Secure System Engineering Methodology". [5] The paper proved to be a seminal contribution in the evolution of threat modeling for IT-systems.
Tactics are the “why” of an attack technique. The framework consists of 14 tactics categories consisting of "technical objectives" of an adversary. [2] Examples include privilege escalation and command and control. [3] These categories are then broken down further into specific techniques and sub-techniques. [3]
Attack trees have also been used to understand threats to physical systems. Some of the earliest descriptions of attack trees are found in papers and articles by Bruce Schneier, [4] when he was CTO of Counterpane Internet Security. Schneier was clearly involved in the development of attack tree concepts and was instrumental in publicizing them.
There are a large variety of different adversarial attacks that can be used against machine learning systems. Many of these work on both deep learning systems as well as traditional machine learning models such as SVMs [8] and linear regression. [76] A high level sample of these attack types include: Adversarial Examples [77]
Provides indicators of actions taken during each stage of the attack. [16] Communicates threat surfaces, attack vectors and malicious activities directed to both information technology and operational technology platforms. Serve as fact-based repository for evidence of both successful and unsuccessful cyber attacks.
An Inference Attack is a data mining technique performed by analyzing data in order to illegitimately gain knowledge about a subject or database. [1] A subject's sensitive information can be considered as leaked if an adversary can infer its real value with a high confidence. [2] This is an example of breached information security.
