Critical infrastructure includes the cyber-physical systems that society relies on including the electricity grid, water purification, traffic lights and hospitals. The solution for organisations responsible for critical infrastructure is to perform due diligence to 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 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 using machine learning to flag abnormal traffic and alert to threats in real time.

Patch:

A patch, sometimes just called a fix, is a small piece of software that's used to correct a problem, usually called a bug, within an operating system or software program. No software program is perfect and so patches are common, even years after a program has been released. The more popular a program is, the more likely rare problems are found, and so some of the most popular programs in existence are some of the most patched.
A patch is a piece of software code that can be applied after the software program is installed to correct an issue with that program. Most software programs may have several patches after their initial release and usually update the version of the program when installed.

Tutorial:- In computer-based education, a tutorial is a computer program whose purpose is to assist users in learning how to use parts of a software product such as an office suite or any other application, operating system interface, programming tool, or video game.

Version:-Versioning is the creation and management of multiple product releases, all of which have the same general function, but are improved, upgraded or customized. While many developers and vendors use the term in different contexts, versioning most often applies to operating systems, software artifacts and web services.

FAQ:-It is frequently asked question a text file containing basic information on a particular subject.
