Study Notes

The Size of Cyberspace

The global cybersecurity market was valued at $75 billion in 2015 and is estimated to reach $170 billion by 2020.
The cyberspace ecosystem is defined by users, points of online interaction (e.g. websites), and activity volume.
The number of smartphones sold reflects the growing number of devices connected to the internet.
Domains, especially those registered with the Domain Name System (DNS), provide insight into the online ecosystem's scale.
The number of websites online reflects the number of points of interaction and provides a measurement of the internet ecosystem's size.
The volume of data transferred across the internet, including mobile traffic, indicates online activity levels, reflecting the potential risk of cybercrime.

The Security of Cyberspace: Vectors, Occurrence, and Damage

A secure cyberspace allows users to interact online without an unreasonable risk of reputational, financial, or rights-related losses.
Insecure cyberspace refers to an environment where internet use exposes users to significant risks.
The level of security in cyberspace can be evaluated based on attack vectors, cyberattack occurrences, and the costs of successful attacks.
