Threat modeling is being applied not only to IT but also to other areas such as vehicle, [26] [27] building and home automation. [28] In this context, threats to security and privacy like information about the inhabitant's movement profiles, working times, and health situations are modeled as well as physical or network-based attacks.
In the first six months of 2017, two billion data records were stolen or impacted by cyber attacks, and ransomware payments reached US$2 billion, double that in 2016. [7] In 2020, with the increase of remote work as an effect of the COVID-19 global pandemic, cybersecurity statistics reveal a huge increase in hacked and breached data. [ 8 ]
As computing crosses the cyber-physical barrier, there is significant effort spent on 'smart' systems, for instance smart cities, smart homes, smart manufacturing and smart vehicles. In the context of cybersecurity, new threats are emerging that target these smart systems. The timeline of cyber-kinetic attacks attests incidents from as early as ...

Remediation (occurs before an event) - The Remediation phase involves precautionary measures and actions taken before an event occurs to fix the known cyber and physical vulnerabilities that could cause an outage or compromise a National Defense Infrastructure, or NDI, or critical asset. For example, remediation actions may include education ...
The lock may be unlocked by picking or by obtaining the key. The key may be obtained by threatening a key holder, bribing a keyholder, or taking it from where it is stored (e.g. under a mousemat). Thus a four level attack tree can be drawn, of which one path is (Bribe Keyholder, Obtain Key, Unlock Lock, Steal Computer).
A vulnerability assessment is the process of identifying, quantifying, and prioritizing (or ranking) the vulnerabilities in a system. Examples of systems for which vulnerability assessments are performed include, but are not limited to, information technology systems, energy supply systems, water supply systems, transportation systems, and communication systems.
The Common Vulnerability Scoring System (CVSS) is a technical standard for assessing the severity of vulnerabilities in computing systems. Scores are calculated based on a formula with several metrics that approximate ease and impact of an exploit.
