Types of cyber security
[/b][/i][/u]

The scope of cyber security is broad. The core areas are described below, and any good cyber security strategy should take them all into account.

Critical infrastructure
Critical infrastructure includes the cyber-physical systems that society relies on, including the electricity grid, water purification, traffic lights and hospitals. Plugging a power plant into the internet, for example, makes it vulnerable to cyber attacks. The solution for organizations responsible for critical infrastructure is to perform due diligence to protect understand the vulnerabilities and protect against them. Everyone else should evaluate how an attack on critical infrastructure they depend on might affect them and then develop a contingency plan.

Network security
Network security guards against unauthorized intrusion as well as malicious insiders. Ensuring network security often requires trade-offs. For example, access controls such as extra logins might be necessary, but slow down productivity.

Tools used to monitor network security generate a lot of data — so much that valid alerts are often missed. To help better manage network security monitoring, security teams are increasingly using machine learning to flag abnormal traffic and alert to threats in real time.

Cloud security
The enterprise’s move into the cloud creates new security challenges. For example, 2017 has seen almost weekly data breaches from poorly configured cloud instances. Cloud providers are creating new security tools to help enterprise users better secure their data, but the bottom line remains: Moving to the cloud is not a panacea for performing due diligence when it comes to cyber security.

Application security
Application security (AppSec), especially web application security, has become the weakest technical point of attack, but few organizations adequately mitigate all the OWASP Top Ten web vulnerabilities. AppSec begins with secure coding practices, and should be augmented by fuzzing and penetration testing.

Rapid application development and deployment to the cloud has seen the advent of DevOps as a new discipline. DevOps teams typically prioritize business needs over security, a focus that will likely change given the proliferation of threats.

Internet of things (IoT) security
IoT refers to a wide variety of critical and non-critical cyber physical systems, like appliances, sensors, printers and security cameras. IoT devices frequently ship in an insecure state and offer little to no security patching, posing threats to not only their users, but also to others on the internet, as these devices often find themselves part of a botnet. This poses unique security challenges for both home users and society.
