Deep Dive: An Introduction to Cybersecurity—Part Three

Executive Summary

• In Part One of this Deep Dive report, we provided a summary of the current cybersecurity environment and discussed its components.
• In Part Two, we discussed the components and characteristics of an advanced attack, the different types of attacks and vulnerabilities, and the different types of hackers.
• Here in Part Three, we discuss new threats/threat vectors and provide an overview of cybersecurity markets and companies.
• Technological advances, such as steady increases in computing power driven by Moore’s law, represent new threats. In addition, the proliferation of mobile advices and the advent of the Internet of Things multiply the number of potential entry points for malware.
• Common technologies such as external USB drives and public Wi-Fi networks can also serve as delivery vehicles for malware. The move to cloud computing presents its own unique security issues.
• Global spending on cybersecurity is forecast to increase at an 8.3% CAGR between 2016 and 2020, growing from $73.6 billion to $101.6 billion. That CAGR is more than double the projected growth rate for IT spending over the period.
• Fortunately, a powerful cybersecurity industry has emerged, and many private and public companies now specialize in providing targeted hardware and software solutions to thwart and minimize the impact of cyberattacks. Venture capital investment in the space is also healthy, keeping the level of innovation high.
