Threat model. Threat modeling is a process by which potential threats, such as structural vulnerabilities or the absence of appropriate safeguards, can be identified and enumerated, and countermeasures prioritized. [1] The purpose of threat modeling is to provide defenders with a systematic analysis of what controls or defenses need to be ...
Computer hacking. Vulnerabilities are flaws in a computer system that weaken the overall security of the system. Despite intentions to achieve complete correctness, virtually all hardware and software contains bugs where the system does not behave as expected. If the bug could enable an attacker to compromise the confidentiality, integrity, or ...
Common Vulnerabilities and Exposures (CVE) is a dictionary of common names (i.e., CVE Identifiers) for publicly known information security vulnerabilities. CVE's common identifiers make it easier to share data across separate network security databases and tools, and provide a baseline for evaluating the coverage of an organization's security ...
An example of a physical security measure: a metal lock on the back of a personal computer to prevent hardware tampering. Computer security (also cybersecurity, digital security, or information technology (IT) security) is the protection of computer software, systems and networks from threats that may result in unauthorized information disclosure, theft of (or damage to) hardware, software, or ...
Zero-day vulnerability. A zero-day (also known as a 0-day) is a vulnerability in software or hardware that is typically unknown to the vendor and for which no patch or other fix is available. The vendor has zero days to prepare a patch as the vulnerability has already been described or exploited. Despite developers' goal of delivering a product ...
In computer security, a threat is a potential negative action or event enabled by a vulnerability that results in an unwanted impact to a computer system or application.. A threat can be either a negative "intentional" event (i.e. hacking: an individual cracker or a criminal organization) or an "accidental" negative event (e.g. the possibility of a computer malfunctioning, or the possibility ...
Data breach. A data breach, also known as data leakage, is "the unauthorized exposure, disclosure, or loss of personal information ". [ 1 ] Attackers have a variety of motives, from financial gain to political activism, political repression, and espionage. There are several technical root causes of data breaches, including accidental or ...
Penetration test. A penetration test, colloquially known as a pentest, is an authorized simulated cyberattack on a computer system, performed to evaluate the security of the system; [1] this is not to be confused with a vulnerability assessment. [2] The test is performed to identify weaknesses (or vulnerabilities), including the potential for ...
